Magine that some members of an aquatic species of motile, photosynthetic protists evolve to become parasitic to fish. They gain the ability to live in the fish gut, absorbing nutrients as the fish digests food. Over time, which of the following phenotypic changes would you expect to observe in this population of protists

OPTIONS:

a.) gain of meiosis

b.) loss of mobility

c.) loss of chloroplasts

d.) no changes would be expected

e.) gain a rigid cell wall

c.) loss of chloroplasts

Explanation:

Some protists such as some members of an aquatic species of motile possess an organelle called chlorophyll which helps in capturing the energy from sunlight to produce food for the organism in the presence of water and carbon dioxide. Since this aquatic species of motile now evolved to become parasitic to fish and now obtains nutrition from fish gut without relying on photosynthesis, the most likely phenotypic changes to expect to observe in this population of protists is the loss of chloroplasts.
