The following information applies to the questions below.
Several organisms, primarily protists, have what are called intermediate mitotic organization.
-What is the most probable hypothesis about these intermediate forms of cell division?
A) They represent a form of cell reproduction which must have evolved completely separately from those of other organisms.
B) They demonstrate that these species are not closely related to any of the other protists and may well be a different kingdom.
C) They rely on totally different proteins for the processes they undergo.
D) They may be more closely related to plant forms that also have unusual mitosis.
E) They show some but not all of the evolutionary steps toward complete mitosis.

Question

Quizplus · Accepted Answer

The presence of intermediate forms of cell division in protists suggests that they have undergone some but not all of the evolutionary steps toward complete mitosis. This is the most probable hypothesis as it is unlikely that these forms of cell division evolved separately from those of other organisms or rely on totally different proteins. It also does not necessarily indicate that these species are not closely related to other protists. It is possible that they are more closely related to plant forms with unusual mitosis, but this is not the most probable hypothesis based on the information provided.
