a) Mitosis, gamete formation, and fertilization.
b) Mitosis, meiosis, gamete formation, and fertilization.
c) Mitosis, meiosis, and gamete formation.
d) Mitosis, fertilization, and meiosis.
e) Mitosis, meiosis, apoptosis.

Humans have 46 chromosomes. This number of chromosomes will be found in __________.

Add labels to the figure that follows, which illustrates a portion of the human life cycle.

A species of rotifer, a small freshwater invertebrate, lost the ability to reproduce sexually millions of years ago. A remarkable feature of its life cycle is the ability to withstand dry conditions. When the rotifer's environment dries out, so does the rotifer, and it can be blown to a new area. Rotifers that land in water will rehydrate and resume an active life. A major pathogen of these rotifers is a species of fungus that cannot survive drying. Some scientists hypothesize that drying rids the rotifers of this pathogen. (a) Design an experimental study to test this hypothesis.
