Fertilization
A) allows several sperm to enter before the egg sets up blocks against entry by additional sperm.
B) prevents ion fluxes across the egg cell membrane.
C) initiates a rapid series of cell divisions.
D) decreases the egg's metabolism.
E) changes protein synthesis without changing the pH of the egg cytoplasm.

Question

Quizplus · Accepted Answer

Fertilization initiates a rapid series of cell divisions that will ultimately lead to the formation of a multicellular organism.

Choice A is incorrect because after the fusion of a sperm and an egg, the egg sets up blocks against entry by additional sperm to prevent polyspermy.

Choice B is incorrect because fertilization actually causes ion fluxes across the egg cell membrane.

Choice D is incorrect because fertilization typically increases the egg's metabolism as it prepares for cell division.

Choice E is incorrect because fertilization can change the pH of the egg cytoplasm as well as protein synthesis.
