Protists represent an important evolutionary step between and A. fungi, plants B. bacteria, animals O C. single celled organisms, multicelled organisms D. plants, animals Peser Selection​

Protists are eukaryotic, mostly unicellular, and mostly aquatic. 'Eukaryotic' means that they have cells with a nucleus and membrane-bound organelles and are similar to the cells that make up our bodies. Because they are eukaryotic, protists fall within the domain Eukarya. Most protists are unicellular, meaning they are only made of one cell. However, some protists are multicellular and are made of more than one cell. Most are aquatic, meaning that they live in the water.

Explanation:

I got this right hope it helps

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

the fossil record provides evidence of a common ancestor to many species.
