Minchanka [31]

C. ferns.

Explanation:

The ferns are ancient plants that have managed to survive until the present. They are not closely related to the dominant plants nowadays, the flowering plants, but instead they are closely related with plants that have gone extinct tens and hundreds of millions years ago. Even though the ferns are not the dominant plants, they have managed to find a niche and firmly hold onto it, so they remained widespread, normally occupying the lower layers of the forests.

Unlike the flowering plants that produce flowers and then seeds in order to reproduce, that is not the case with the ferns. The ferns actually reproduce through spores, being widely dispersed by the wind and managing to spread out and reproduce over relatively large territory very quickly.

iVinArrow [24]

The question has incorrect option, however the question can be answered by the general explanation. On the basis of the general explanation the answer is as follows:

Answer:

The correct answer is - Serine has a small side chain that can fit in any relatively polar environment.

Explanation:

Serine is an amino acid that have a small side chain in comparison of other amino acid and can be replaced by another amino acid with very least effect on the structure and function of a particular protein as they can fit in any relatively polar environment.

Serine have hydroxyl group in their side chain. It is polar amino acid that can easily establish itself in any polar condition and cause least changes in protein structure and function.

Thus, the correct answer is - Serine has a small side chain that can fit in any relatively polar environment.
