question 2 (2.5 points)
the colonial theory of animal origins states that animals
migrated on land from sponge colonies in the ocean
originated in the colonial geologic period
evolved from autotrophic green alga colonies
evolved from a heterotrophic protist that formed colonies
colonized land before they colonized the seas

Explanation:

The colonial theory of animal origins posits that animals evolved from a heterotrophic protist that formed colonies. Sponges are among the earliest animals, and the colonial protist ancestor would have had similarities in cell - cell interactions and differentiation potential. Autotrophic green algae are plants (or plant - like organisms) and not the ancestors of animals. There is no "colonial geologic period." Animals originated in the sea, not on land, so the idea of migrating from sponge colonies on land is incorrect. Also, animals colonized the seas first.

Answer:

evolved from a heterotrophic protist that formed colonies
