5) With the exception of identical twins, siblings who have the same two biological parents are likely to look similar, but not identical, to each other because they have A) identical chromosomes, but different genes. B) the same combination of traits, but different genes. C) a similar but not identical combination of genes.

B) Prokaryotic chromosomes are more complex than those of eukaryotes. C) Most prokaryotes reproduce by binary fission. D) In prokaryotes, daughter chromosomes are separated by an active movement away from each other and the growth of a new plasma membrane between them. 8) Eukaryotic chromosomes differ from prokaryotic chromosomes in that they A) are simpler.

15) The process by which the cytoplasm of a eukaryotic cell divides to produce two cells is called A) binary fission. B) mitosis. C) cytokinesis. D) telophase. 16) Looking into your microscope, you spot an unusual cell. Instead of the typical rounded cell shape, the cell has a very narrow middle separating two bulging ends. It sort of looks like the number 8! Then you realize that this cell is A) about to undergo mitosis. B) in the G1 phase of interphase. C) in the S phase of interphase. D) undergoing cytokinesis....
