Accepted Answer

Oogenesis results in the production of one haploid ootid (which matures into an ovum) and polar bodies that typically degenerate.

Question 10

Which of the following statements about blocks to polyspermy in sea urchins is false?

Accepted Answer

The fast block does not cause release of acrosomal enzymes, but rather results from a change in electric-charge difference across the plasma membrane of the egg.

Question 15

Reproductive systems involving external fertilization are most common in

Accepted Answer

External fertilization is a process in which eggs are fertilized outside of the female's body, usually in an aquatic environment, where the sperm and eggs are released into the water. Therefore, external fertilization is most common in animals that are aquatic.

Question 16

The term "dioecious" refers to

Accepted Answer

The term "dioecious" refers to the presence of separate male and female reproductive systems in different individuals of a species. It is not related to patterns of inheritance, circulatory physiology, patterns of cleavage in developing embryos, or the evolutionary origin of species.

Question 17

Use the following to answer questions:
Match the cell states listed below with the description of a cell in each question that follows. Each item may be used once, more than once, or not at all.

Question 18

In male gametogenesis, the second meiotic division produces four haploid

Accepted Answer

The second meiotic division in male gametogenesis produces four haploid spermatids.

Question 19

Parthenogenesis, or the development of offspring from unfertilized eggs,

Accepted Answer

Parthenogenesis has been confirmed in some species of whiptail lizards, and the offspring produced through parthenogenesis are always female. This is because parthenogenesis relies on cyclical hormonal states and the lizards have mechanisms to stimulate development of unfertilized eggs. Therefore, the correct choice is E, as both options C and D are correct. Option A is incorrect as parthenogenesis has been confirmed in several species, and option B is incorrect as parthenogenesis occurs in a variety of animals.
