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.

Which is more active in cellular respiration: a germinating or a non germinating pea?
Morgarella [4.7K]

A germinating seed. This is due to the fact that the cells of a germinating seed are actively dividing as the plumule and radicle grow. This growth requires energy and this is derived from cellular respiration of the stored food in the cotyledons.
