Newton's Third Law





This week in science, we learnt that if there is an arrow on a force diagram that is facing down, the object is accelerating or decelerating. It is not showing an object going in a direction.
Newton's third law claims that the amount of force exerted by an object gets exerted back on the object that exerted that the force. This is cenerio a i am using as an example: (to the left)
The young girl pushes the old lady and soon they both will go in opposite directions the same distance from the origon that the girl had first applied the pushing force.
Newton second Law explains that force is equal to mass multiplied by acceleration. F=(m/a)
And that concluded our week in science.

Force part two

this week in science, we learned more on the unit force. We discovered that there is gravity,"Force of the Earth puling on us": is weight.
We also discussed the idea of the mass or massiveness. Mass is the amount of matter that is consisted in a substance.

Mass is what gives us weight. It is because the mass of a substance is pulling down on us, that of force that is pulling down on us gives us our weight!

In space, there is no gravity until we come close to a huge mass like the moon or another planet. So, if we launch a rocket into space, the rocket will stay in the course that we put it in. Then the rocket will start accelerating toward a mass because of the mass' gravity is bulling down on the rocket toward the mass. So eventually, with the gaining acceleration of our rocket, the rocket will crash into the mass.

Since the moon has a lesser gravity than the Earth, the moon will have a less pull on the objects near it. Or less gravity in the objects near it.

Force


This week in science, we learnt that there is something that makes things and us move. and that is force. Force is a push or a pull on a object.
So, we learnt how to make force diagrams. a force diagram is a diagram that shows all the different forces exhibited on the object of interest.
If the object of interest is staying in the air, either held up or stagnant in the air, that means there is a positive force and is contradicted by a negative force and so, that means there is 0 newtons being exited on the object of interest which means the object is staying in the air or is being held up.

This is how i know how many newtons are being applied to the object to make it stay in the air:(to the left)

Science this week

Well this week in science we did not do many things. We just went according to the packet that we have all the Kinematics questions in. We did learn something new about velocity arrows. This is the same thing as the dot diagram or the motion diagram except this has arrows to show which direction that the object of measure is traveling in. Mark, Chris and i did a lab on how to measure the distance traveled when we hit a basketball with a hammer. We found we created a graph ob it and we were able to conclude that the basket ball starts off at a fast speed, then slows down constantly over a long period of time. Then on Friday, we had a partner quiz on all the things that we had learnt. We were supposed to make a graph on how fast somethings was going. And, that concluded our week in science
This is important for us to learn so we know how to calculate speeds pf things later in life if we are talking a physics career.

Science in school this week

this week in science, We only did tings about lab report on how we could find the normal speed that our object was moving at.
Our objective was to locate where in six meters would a fast car and a slow car, we took the speed of the fast car by measuring how long it took the car to travel six meters, then we divided the six meters by the seconds the time that it took the car to accomplish the six meters. The equation that we used was: Change in Position
Change in time

So, the fast car's speed came out to be 14.56 seconds over the distance of 6 meters.

The slow car's speed came out to be 27.6 seconds over 6 meters.

The fast car's speed came out to be 0.411 meters/seconds

The slow car's speed was 0.22 meters/seconds

Thats almost half the speed of the the fast car's speed.
So, we predicted that the the crash between the two cars shall take place somewhere in the six meters closer to the slow car.

Before we did this in class, we learnt what a slope was. It is the same thing as the speed. You calculate the slope by taking one point of the position and subtract the second point from the first point. Then divide that by the first point's time and subtract the second points time.

cow eyes!!!

i didn't blog when we did the cow eyes because i had the flu and was out on the Wednesday. The cow eye dissection was very important because that showed us how the eye works and how it lets the light pass through the eye causing us to see This is very important because we should know how our eyes use refraction to let us see and how the principals of light are applied to how we see.
We got to see some of the following parts in the cow's eye:
  1. Retina
  2. Optic nerve
  3. lens
  4. Iris
  5. pupil
  6. Cornea
  7. Optic disk


It was pretty cool.
what i learnt was that the light would enter the eye and refract in the Aqueos Humerous and go through the pupil and refract in the lens and goes to the retina and casts the picture of what the light bounced off of and thats how we see.

A three day week in science

This week, we only had three days to learn things in science. On Monday, we took a partner quiz reviewing a lot of things of that happened in science to make sure that we remembered those things.
Trend lines
According to my understanding, A trend line doesn't have to exactly fit the dots that were placed on the graph because it shows how much uncertainty is in the results on the graph.


The black trend line shows that the results could have been according to the path of the line and no the results displayed on the graph.

On Wednesday, we discussed or homework which is about functions or equations to help create an index. this is an example function like we got in our home work.

Bob starts at t1 hours and reaches her destination at t2 hours at a position h1 and reached a position of h2, our function would be... t2-t1*h2-h1.
This is important to us because functions help us calculate complex things that we will need for jobs like rocket science and professions in math.

science on the week of halloween

this week in science, i was sick from the flu until thursday:
On thursday, i had no clue what was going on.

we talked about how an index works. this is the most simplified ratio when making a ratio on a quantitative observation.

We use index making when there is something moving per a time measure.
suppose a pop corn machine makes 10 corns in the period of 7 seconds. This is a ration of how it looks before simplification

10/7=?/1

so, we divide the ten by seven and get 1.428.
that was the rate of how many kernels were popped in one second. this is a simplified index.


This is important to us because we should be able to know how to calculate simplified ratios for different rates.

this week in science

this week in science, we discussed the last things that we would need for the test on Monday the 19th.
we discussed that the waves in a pool spread out and bounce off objects just like they do from a light source bouncing off objects.

When there is an object blocking a wave from passing, the part of the wave that is blocked will be stopped and will not pass, but the part of the wave that is not blocked, will pass around the object blocking the other half of the wave.
The other thing we learnt was that the different surfaces that light hits off, has a different texture, so therefore, it reflects the light in a different manner.
We also learnt that when light hits glass, the light would refract because when light goes from a less dense medium to a higher dense medium, the light slows down and changes direction and this is called refraction.
When drawing this refraction, the light always goes through the denser medium and bends down towards the normal line. There is a specific formula but Mr. Finley and Mr. Segen said that doesn't matter.

This is important to us because when water is on our wind shield, the water refracts and makes every thing seem bent because of refraction that takes place when the light passes through the water on the wind shield.

Sunday, October 11, 2009

this week in science

this week in science, we were discussing what other forms that light could travel in other than straight lines like we have expressed in previous discussions and experiment drawings that we have drawn.
We have read that in the 1600's, Isaac Newton thought of a ray diagram that consists of light rays traveling in the form of waves or particles. The wave model is better to use when we are talking about shadows. We explain shadows as when the waves gets topped by a solid and still bend around the object making the dark part very crisp. But as the waves hit the edge of the solid substance, they bend around the substance and travel while spreading out and when they hit the ground, then they have light around this darkness which is caused by the light blocked off by the solid substance.
The particle model explains how we see. the balls or particles bounce off objects and go into my eye causing me to see what ever they bounced off.
We were led into this discussion on how else does light travel. So we compared i to when we bounced basketballs and dripped water droplets into a small collection of water and saw how the waves\ripples traveled through the water and would not go behind a solid substance which was in the water.-the ripples would not go through the solid substance, but they go around the solid mass and spread all over the water quickly.

Back to the particle models
The particle model claims that the particles bounce off the masses that they hit bouncing particles everywhere. and then, those particles go into our eyes letting us see what the y bounced off of.
The wave particle model claims that the waves are just like the light rays and they travel like the light rays and they bend around a mass and and light casts on the ground. and the parts that the light could not reach due to the mass, is called the shadow.
Thats what we learnt in science,(i think) jkjk

this scientific ideas that we should know about shadows are: when we want ot make a shadow, all we have to do is stand and we know how to focus our shadow when we want to and make our shadow fuzzy and blurry if we want.
We would be able to keep something cool if we want by blocking off light that could fall onto the object we want to keep cool.

scince in October

This week in science,
this week in science, i learnt that when the laser i pointed at a mirror, the same angle that it is shot at, in the same angle, the laser will leave the mirror.
as you see, the ray comes and hits the mirror at a at a 45 degree angle. Then when leaving the mirror, the light ray leaves at the exact same angle that it came and hit the mirror.

I was able to test this in class because in my experiment, we glued a protractor and pointed a laser pointer at a certain angle. Then we put some flour and poured it on the laser beams. and the laser beams bounced off the particles of dust showing us the direction of the beam of laser. Then, we were able to see that the angle that we pointed the laser at, on the opposite side, the laser left at the exact same angle.

I learnt this by thinking
"how will we be able to measure the angle that the ray of light comes and leaves at?"
Then when we are measuring angles, we need a protractor. So, we have to include a protractor. and we need to see the ray to be able to measure it. so, we but some dust in the beam for the beam to bounce off the dust and we were able to see the rays, and we measured the angles they came and left. At 80 degrees, the rays of the laser came and left at the same angle.

We should Know this because in case we want to light some place up for a laser show, we should be able to reflect the light in directions we want to move the light where we want to.

this week in science

this week in science, class, some of the science ideas that i learnt were that when the laser pointer points the laser at something and it bounces off the solid object that it was pointed, and reflects to many different places sending light rays all over the place. And so, the light from the laser pointer comes into your eye after reflecting off the wall and thats how you are able to see the laser point on the wall on teh other side of the room.

I learnt this by thinking
"how are we all (everyone in the class) able to see the little dot from the laser on the wall from the angles we were looking from. so, we decided on the conclusion that the light reflects off the wall and
the rays go in many directions going into our eyes. then we are able to see the dot there."

It is important to know this because in life, if we do go into the field of medicine for the eye, we should know how the eye works in order to diagnose a problem in the eye.

9/14/09

this week in science, we started our light chapter. We had to conduct experiments in which we tested how a beam of light gets from the laser pointer to the wall or any solid object. likewise a bulb to all around us.

Then we had to figure out how we are able to see this happen. I found this really helpful website that helped me a lot understanding how the eye works.
This is the link to it


this week i learnt that we always have to use our scientific knowledge to help us a round in life.
this week, we had to create an experiment on how we could test how a laser could reach a wall and how it gets to our eye for us to see. i had to devise an experiment to test how this works. in another case, last week we had to think of ways to find out the truth whether mr. finley watches kids on close captioning tv, we had to create an experiment to find out if he really does this and why he does this.
So, we have to create experiments all the time and think of possible outcomes that could affect us.
i learnt these ideas by
1 researching(how the eye works)
2 thinking about when in life i use my creating experiments skills and testing them.
3 by thinking of all the possible ways some thing could happen to effect us.(laser pointer)

so, it is always good to have these ideas in mind because in life, we will always need them.

Saturday, June 6, 2009

this week in science, we started meterology. this is the study of the weather. We learnt how to create clouds and how evaporation works. We also had to read a lot of online text books.
When we created clouds, we gave the water droptets a different molecule to attach onto when mr. finley added the smoke on the bottle. This let the watter particles surround the smoke molecule and form a cloud and create condensation.
We also learnt that when things get hot, the particles move away from eachother and the object becomes bigger. SO, if a ball is not fitting in a hole,(dont think badly) then heat the hole. The whole's particles will go away from eachother and therefore, the hole will be bigger ot fit teh ball in. When we run something in cold water, the particles contract and the object becomes smaller.

Science

This week in science, we had a day off so, we had a shorter week.
On tuesday, we started looking at teh documertries.  I learnt that one of the things that make us is bipetilism. Thi sis when we could walk upright on both legs.
Then we also discussed the way we are classified. This is how we classify things/species
categories: Kingdom, Phylum, Class, Order, Family, Genus, Species.

There is a simple pneumonic that can help students remember the organization of nature:Kangaroos Play CellosOrangutans FiddleGorillas Sing.

If we take a Ring-tailed Lemur, we can trace it through the hierarchy of nature, taxonomy as follows, it belongs to:

The Animal …Kingdom 
sharing with all other members of this group the need to feed on organic matter (unlike plants which can create energy using light and minerals)

The Chordate (or vertebrate) … Phylum 
sharing with all other members of this group of animals, a back bone with a hollow nerve chord

The Mammal … Class
sharing with all other members of this group of vertebrates, the ability to feed their offspring on milk and having a body covering which includes fur

The Primate … Order
Sharing with all other members of this group of mammals, a thumb that can be opposed to the other digits, binocular vision and various more broadly defined characteristics (including high intelligence, relatively long maturation period for the young, dental similarities, tendency for complex social organization, and generally bearing one or two young)

The Lemuridae … Family
Sharing with other members of this group of primates, a slightly longer nose, smaller brain, long slender limbs, a tail, more specific dental features including the grooming comb formed by the lower incisor and canine teeth

The Lemur … Genus 
Sharing with other members of this group of lemurs, scent marking methods, vocalizations, aspects of social structure and overall body shape

The Ring-tailed Lemur … Species

I have to cite this: http://www.tigerhomes.org/animal/curriculums/lemurs-4.cfm

Just like that, we are classified live this:

 Kingdom: Animalia  

Phylum: Chordata Class: Mammalia Order: Primates Family: Hominidae Genus: Homo Species: sapiens So, we are classified as Homo Sapins. Thi s is the most dynamic way of saying what we are.

This week in science

during this week in science, we did not do too much due to other things. We first discussed the Lamarkian evolution. This was a theory which if one species uses a trait that it wants, over a long period of time, the trait will become to them and their children will also have that trait. This is partially true. When we want to change ourselves, we must do so to suit our enviornment. We also learnt how we slowly evolved. We started as apes. then went to then centuries from thhen, we have evolved into the walking humans we are today.
The extra credit for this week is what primate do we fall into?
answer: We fall into the higher primates category. this is so becasue we have a more complex brain structure and are therefore smarter. Apes fall into this category too.
 The other category is the lower primates group. this conists of animales like leamurs.

Sunday, May 17, 2009

This week in science, we learnt about evolution and matural selection in iguanas. The iguana originated in the color green and was a land mammal. Then,somehow the iguana's decendents got to the galapognos Islands. then they started sto evollve. The iguana was unable to live very much. Therefore, they evolved very slowly. The iguana feirst survived on some vegetaion that was left there on the island. Then they reproduced. Then the iguanas died from natural process and the children feasted on the parent's bodies. Then like that, the children reproduced and the th eparents died to let the chi;ldren eat their bodies. Like that, the iguana populaiton increased on the galapogonose islands. Then the iguanas had a genetic mutation. This gave them more possiblities of survining at that location. exp...(camoflagueing into rocks,gills to survive underwater.) And so, the iguanas survived the galapognose. Then on Friday, we had a quiz on this.

Sunday, May 10, 2009

This week in science

This week in science, we did not accomplish much but, it was a handful. On Monday, we finished presenting our cockroaches experiment data. Then on Tuesday, we debriefed on the experiments. We learnt that the traits that are in the roach will help it survive in the wilderness and face the enviorment that it lives in. 
Then for the rest of the week, we went on to simulations that teach us about one main idea: The traits that we have are to help us live in the area that we live in. When we first came to humans, we did not loose our fur from monkeys, all of a sudden, we evolved and changed in to humans with skin and no fur after many generations of changing. SO, slowly, our DNA changes to make our offspring bodies in to  more suitable to the enviorment that we live in.
That is what i hypothesize the reason for us having us do this unit.

Cockroaches!

This week in science, we conducted experiments on cockroaches to see whether they would hiss or not. This week, we had to design an experiment and test it out. Well, you could guess, ours was about whether the roach would hiss or not. We figured that it hisses if i is scared or agitated and maybe because it wants to scare off it's enemy. We had three categories of tests; Physical, psycological and enviormental tests.
The Physical tests were when we, the testers touched the roach and pushed it a little, and maybe assulted it a little.
 The Enviornmental tests were tests in which we replayed the conditions that the roach had to face in its everyday lifestyle.
  The psycological tests were tests that we used to effect the roaches' mind. We called the roach bad and mean names to make them feel bad.(things htat should not be heard.)
The results really fit the data. We had the roach hiss when ever we touched it or physically assulted it.
When we did the enviornmental tests, the roach never hissed.
When we did dthe psycological tests, we called the roach bad names, but it never responded.


Based on the results, we can conclude that the cockroach knows about its enciornment and does not hiss because it is scared because it just knows its home enviornment. We were not sure that the roached Knew about the mean things that we said to it.












Friday, April 10, 2009

This week, we went on a field trip. This is five scientific things i learnt on the trip;
1)the mud in a bog is full of tanning acides that when a man was thrown into the bog, then picked up 1000 years later, th ebody was fully preserved but the body was tanned like leather.
2)When you are out in th ewilderness, and it is cold. You do not have any thing but sticks to build a shelter, build a shelter low to the ground. this will thake your body heat and warm the small area that you are in.
3)Salamanders breathe from their skin!
4)Cratures that live in a stream have a stronger body/aerodyminicle body to fight the current of the water.
5)When a stromg wind is coming,and you have a high structure, the wind could snap the structure in half. Tha tis why you should put holes in the building so the air passes through the building

this week in science

this week in science, we did many things. on Monday, we worked on my project and i had to do the smart technologies assignment. on tuesday, i handed everything in and my stress wasover. On wednesday, i had to study for the test. Then we got to play with cockroaches. They were really cute. They had little cute legs with fuzz on them. they had a hard shell and and when you tried to pick them up, they hissed like a snake at you. They are awesome!
On thursday,we had ht great science test! It was not so hard but you had to write a lot.
On friday, we finished our tests and we played with the cockroaches again.l

Genetic Variety in Reebops







When making the lady bugs in this project, genetic variety is very important. First of all, without genetic variety everything looks the same. For example, in the reebops, if the first generation or the parent bug was a red eyes which was recessive, and the bug breeded with a black eyed dominent bug, the black eyes will be dominent. Then if the other bug which the origional parent bug breeded with was hetrozygous, the children of the bugs have a 25%chance of being red eyed. I had an ugly bug born in my fourth generation The bug had no wings, yellow mutation and no dots with short legs. This did not look very good compared to the previous bugs of mine. Sooo, if you think you are ugly, blame your parents for having you the way you are.



Genetic diseases are heredity. So, for example, if both the parents of a bug had familial Dysautonomia, the bug will probably get the disease depending wether if the parent is homozygous or hetrozygous.



If you think you are special, and maybe you are, without genetic variety, every one would be special with your talent. You will not be very special then.



During the mating, we sometimes had the same color for our chromosomes, so we had to use some type of symbol to repersent our own chromosome. Therefore, we are a little different. Without variety, we are all the same. These are pictures of bugs that look alike but are tottaly different to prove my point.(top)



Monday, March 9, 2009

This week in science;

on Monday, we talked about incomplete dominence, or which the child is a mix of both the parents.


(Exp.---white flower*Red flower=Pink flower.


This is a really cool site that told me a lot about incomplete dominence:::


http://www.hobart.k12.in.us/jkousen/Biology/inccodom.htm



The next day, i got a migrane and had to miss the first 4 periods of school, so this is what i learnt from that day:when you have 2 dominance for a trait, it becomes a co-dominant. This happens in blood when there is two DOMINANT blood types mixed like A and B (AB).Then on top of that, there is the proteins that attach on to the blood types.(positive and negative.) The positive always is the dominant one.
I don't know what happened the rest of hte week in science.

Sunday, March 8, 2009

This week in science, we did many things, First on Monday, we had a snow day, on tuesday, we learnt on how the Class' results did almost support the whole school's results.
On Wednesday, we went over some of the things about Genetics. Then Finley told us some things about the Lab that we will be doing th enext day. We created "egg and sperm cells for the experiment."
On thursday, we learnt that the Genetic Mutation always results in the strand mutated becoming the Dominant Gene.
On Friday, we did the experimen of mixing uop sperm and egg cells and looking at what the outcomes would look like. Then we had a quiz that we had to do at home whch I just hot to see.
This is what tje quiz was

Spiderman and Spidergirl got married and soon found out that
Spidergirl was expecting a son. Spiderman couldn't wait to
welcome his new son into the world and was looking forward
to fighting crime with him. However, when he was born
Spiderman realized that his son does not have his parents'
"spider" quality. Spiderman believes that the baby might
actually be Batman's! (Remember, Batman has ZERO special powers)

What do you know about the "spider" trait?

What could spiderman and spidergirl's genotypes be?

Did spidergirl have batman's baby? Support your answer with an explanation

Hard Quiz.

Science

This week in science, we learnt how to make a punnet square and what a Homozygous or a Hetrozygues is.
A homozygues is a species that has the same trate from the mom's side and the Dad's side.
A hetrozggues is a species that has two different trates. One from the Dad's side and one on the mom's side.
The recessive trait is always the trait that does not take over unless there are two rrecessive traits, which makes it a homozygues.
If hter is a dominent gene and a recessive gene, the dominent gene always takes over.
This is a great video that i found that helped me understand Genetics.

M-E-I-O-S-I-S

This week in sceinnce, we finished learning on how Meiosis works and started Genetics. On Monday, we learnt that Meiosis is really related to Mitosis. We also learnt that when a sperm cell and an egg cell meet and come together, It is called a Zygote. Then, we went on this website and saw how the DNA gets into the sperm cells. That website was very helpful in learning how the DNA gets spread out. Next, we wraped up our celluar reproduction with a quiz on the Meiosis and Mitosis. And on Friday, we went on this website and learnt about Gregor Mendel and how he breeded peas and how he found ou thow we lok like our parens.

Sunday, February 8, 2009

Meiosis

This week in science, we learnt about the process of meosis and how it relates to mitosis.
The first stage of meiosis is:
Interphase I: Whe the cell goes through its normal life.
Prophase I: The centrioles pull apart the one
Metaphase I: the chromosomes or homolagues pairs line up on the metaphase plane and are ready to be seperated by the centrioles.
Anaphase I: During anaphase I, the cell's spindle fibers pull the chromosome pairs and start to go to opposite poles.
Telephase I: During telephase I, the cell's nucleas starts to reform and th edaughter cell's nucleas also starts to reform and finishes to reform.
Cytokinesis I: During cytokinesis, The cell's membrane reforms and there are two indevidual cells now.

Meiosos II
Interphase IIDuring Interphase two, the cell's centrioles come and surround the nucleas and start producing spindle fibers.
Prophase II: (Interphase II)
Metaphase II: During Metaphase II, the cell's chromosomes line up ready to be seperated.
Anaphase II: During Anaphase II, the cell'schromosomes are pulled apart just like meiosis.
Telophase: During Telophase II the cell's membrane starts to close off creating 4 new cells. Then the nuclear membrane reforms.
Cytokinesis II: During cytokinesis II, the cell's break off from each other creating 4 sperm cells.

Mitosis(Cell reproduction)

Over the week at science, we did a lot of theings. Here is what we did:
On monday, we talked about the things that happen mitosis and the stages/phases that occur during Mitosis.
Interphase-the phase that the cell stays in and when the cell copies the DNA/chromosomes for reproducton.
Prophase- Is when the nuclear envelope wears away exposing the sister chromotids.
Metaphase- When the cell's centrioles use the spindle fibers to pull apart the sister chromotids.
Anaphase- Is when the cell's centrioles seperate the sister chromotids and go to the other ends of the dividing cell.
Telophase- Is when the cell's nucleas starts to reform in the prexisting cell and the daughter cell just created.
Cytokinisis-Is when the cell's membrane reforms around both the parent cell and the daughter cell and the cells are now no longer dependent on eachother and Mitosis ends.
Then we had a Quiz on that stuff

Science

This week in science we did a lot of things. We had a unit test on how celluar respiration and on the things before that.
On Tuesday, we reviewed for the teas on Tuesday by watching a video on how our skin and body is crawling with living organisms. On Wednesday, we had the test on The things we learnt on cells before.
On Thursday we looked at cells under the microscope to learn about mitosis, which is when cells reproduce.
On Friday, we went to a website that shows the different stager of mitosis and did a workshhet on it. Here is the website: http://www.cellsalive.com/mitosis.htm.

Science This Week

This week in science, we studied how a cell reproduces a cell. The process is called mitosis. The cell first starts as a cell with a nucleas, (a regular cell), Then it gets a fuzzy circle around the nucleas.Next there is a giant nucleas. And finally, the cell divides into another cell and another cell gets created. The exact DNA of the prexisting cell was copied and then put into the new cell.

This is a website that shows an animation of this:http://www.cellsalive.com/mitosis.htm.
We also learnt how mRNA gets translated by the ribosome. This is a good show to go to that will explain how transcription and translation takes place:http://www.youtube.com/watch?v=nl8pSlonmA0

Thursday, January 8, 2009




During the week in science, we did a lot of things.Here is what we did;




We learnt how to decifer DNA and RNA reading. this is an image of RNA being translated by a ribosome.











Below is a website that explains mRNA translation.
http://www.biology.iupui.edu/biocourses/N100/2k3ch13dogma.html



When a cell needs to make new proteins, it sends out a part of its DNA called RNA. That Messenger RNA goes to the ribosome that is on the outside of the nucleas and gets read by it. The ribosome then creates the proteins that the mRNA told it to make. Those proteins then go to the golgi apparatus to get sent to the part of the cell that needs
it.

We also learnt why a fish cannot survive out of water.This is how: When a fish is in the water, the fish's gills filter out the water and other chemicals in the water. Then it only allows the oxygen to get into the fish so the fish could breathe.
If the fish was out of the water, the fish would not be able to breathe because the gills of the fish cannot filter the other gasses in the air and only let the oxygen in. Therefore the wish will suffocate to death.
