Assume 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?

A) no changes would be expected
B) loss of motility
C) gain of a rigid cell wall
D) gain of meiosis
E) loss of chloroplasts

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
