Please help i need to finish this today before bed and i need a passing grade to start my next assignment. Proteins have a variety of functions within a living cell. Describe at least three of the possible functions of proteins, and explain how proteins can be so diverse when there are only a limited number of different amino acids.

Answers

Answer 1

Answer: an answer might be - Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.

Where does photosynthesis occur??

Answers

photosynthesis occurs in the chloroplast.

Photosynthesis occurs in the chloroplast of a plant cell. To get into even more detail, the light-dependent reaction occurs on the thylakoid membrane and the light-independent in the stroma.

Hannah is comparing a rock from a riverbed and a rock from deep underground. One is very smooth, and the other has very rough edges. Explain why each rock was probably found in that location.

Answers

The rock found in the riverbed that is smooth is from the result of weathering of water in the river and erosion. The rock deep underground was most likely a product of erosion. The dirt and ground above it were eroded and displaced there to cover the rock.

Explanation:

A rock dropped on the moon will increase its speed from 0 m/s ( its starting speed when first dropped) to 4.9 m/s in about 3 seconds. What value do you calculate for the magnitude of the acceleration of gravity on the moon?

Answers

Answer:

Acceleration, a = 1.64 m/s²

Explanation:

It is given that,

A rock is dropped on the moon, its initial velocity u = 0 m/s

Its speed increases from 0 to 4.9 m/s, v = 4.9 m/s

Time taken, t = 3 seconds

We have to find the magnitude of the acceleration due to gravity on the moon. The magnitude of acceleration is given by :

Acceleration, a = rate of change of velocity

$a=(v-u)/(t)$

$a=(4.9\ m/s-0)/(3\ s)$

a = 1.64 m/s²

So, the value of acceleration of gravity on the moon is 1.64 m/s². Hence, this is the required solution.

Acceleration = (change in speed) divided by (time for the change).

From the figures given in the question, the acceleration is ( 49/3 ) =

16.33 m/sec2

There's no way that this is happening on the moon. That acceleration is about 67%

greater

than the acceleration of gravity on the earth's surface. It should be about 83%

less,

or about

1.63 m/sec

I see the problem now. The '49' in the question should be '

4.9

apex- 1.63 m/s2
