D

Question 2

________ Contains enzymes that digest a path for the sperm
A) Polar body
B) Capacitation
C) Acrosome
D) Zona pellucida
E) Pronuclei

Accepted Answer

The acrosome is a cap-like structure on the head of the sperm that contains enzymes which digest a path through the zona pellucida, allowing the sperm to penetrate and fertilize the oocyte. Polar bodies are small cells produced during oogenesis that contain discarded genetic material. Capacitation is a process sperm undergo in the female reproductive tract to become capable of fertilization. The zona pellucida is a protective layer surrounding the oocyte. Pronuclei are the nuclei of the gametes that come together after fertilization.

Question 12

________ Haploid nuclei that fuse to form a zygote
A) Polar body
B) Capacitation
C) Acrosome
D) Zona pellucida
E) Pronuclei

Accepted Answer

Haploid nuclei that fuse to form a zygote are the pronuclei. They are formed by the fusion of the sperm and egg nuclei during fertilization. The other choices (Polar body, Capacitation, Acrosome, Zona pellucida) are not related to the fusion of nuclei during fertilization.
