Correct! Each gamete has a total of 46 chromosomes. 6 / 6 pts Ques ! on 16 Your Answer: Label the regions of reproduc " ve system below: (A-E). To receive full credit you must name specific regions. A: _________________ B: _________________ C: (in blue) _______________ D: _________________ E: _________________ A. Vas Deferens B. Seminal Vesicle C. Ejaculatory Duct D. Prostate Gland E. Bulbourethral Glands A: Vas Deferens B: Seminal Vesicles C: Ejaculatory Duct D: Prostate gland E: Bulbourethral gland 5 / 5 pts Ques ! on 17 Your Answer: Name and discuss the purpose of the region of sperm indicated by the arrow in the figure below. The region indicated would be the head of the sperm. It is en " rely nucleus which has a cell called acrosome that contains enzymes that breaksdown the membrane of the egg to help the sperm penetrate. The head is almost en ! rely nucleus containing the cell DNA with a crown called the acrosome which contains enzymes that breakdown the membrane of the egg to allow the sperm to penetrate. 3 / 5 pts Ques ! on 18 Your Answer: Discuss in detail the ac " on of sperm needed to fer " lize an egg. Sperm cell releases the enzyme to destroy the corona radiata and accomplishes release of acrosomal to make a hole in the membrane of the egg allowing the sperm to combine to the egg. The egg releases chemicals that a " ract the sperm. Sperm cells release enzymes that break apart the corona radiata, follicle cells surrounding the egg. Once this is accomplished, more sperm release acrosomal enzymes that make a hole in the membrane of the egg, allowing one sperm cell to combine with the egg. When the union of egg and one sperm occurs, the membrane of the egg instantly chemically changes, preven ! ng other sperm from penetra ! ng the egg. 4 / 4 pts Ques ! on 19 Which of the following is true concerning human cells?
