Answer: rocks

Explanation:

Most of the phosphorus on earth comes from the rocks typically from the phosphate rocks. It takes millions of years to form these rocks under the surface of the earth crust. The rocks are typically formed by the geological processes in the geosphere. The largest sources of the phosphorus comes from the sedimentary rocks. This can be found in the sediments found over the oceanic floors. The phosphorus can also be found in the animals, humans, soil and in plants.

9. Which structure helps animal cells maintain their shape?
ludmilkaskok [199]

Answer:

<em><u>D. Cytoskeleton</u></em>

Explanation:

It is really none of these answers. The correct answer would be a microtubule which is a component of the cytoskeleton which is in the cytoplasm.

The Cell Walls are only in plant cells so that won't work.  So, A wouldn't work.

Chromosomes are the things that both your parents give you as genes. They have nothing to do with keeping the structure of the cell alright.

Cytoplasm cannot be a answer choice because, the thing is in it but, it doesn't do anything with it. So C wouldn't work either

The correct answer is microtubule however, it is a component of cytoskeleton so therefore, that is your answer.
