Correct!Each gamete has a total of 46 chromosomes. 6 / 6 ptsQues!on 16Your Answer:Label the regions of reproduc"ve system below: (A-E). To receive full credit you mustname specific regions.A: _________________B: _________________C: (in blue) _______________D: _________________E: _________________A. Vas DeferensB. Seminal VesicleC. Ejaculatory DuctD. Prostate GlandE. Bulbourethral GlandsA: Vas DeferensB: Seminal VesiclesC: Ejaculatory DuctD: Prostate glandE: Bulbourethral gland5 / 5 ptsQues!on 17Your Answer:Name anddiscuss the purpose of the region of sperm indicated by the arrow in thefigure below.The region indicated would be the head of the sperm. It is en"rely nucleus whichhas a cell called acrosome that contains enzymes that breaksdown the membrane ofthe egg to help the sperm penetrate.The head is almost en!rely nucleus containing the cell DNA with a crowncalled the acrosome which contains enzymes that breakdown the membraneof the egg to allow the sperm to penetrate.3 / 5 ptsQues!on 18Your 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 accomplishesrelease of acrosomal to make a hole in the membrane of the egg allowing the spermto combine to the egg.The egg releases chemicals that a"ract the sperm. Sperm cells releaseenzymes that break apart the corona radiata, follicle cells surrounding theegg. Once this is accomplished, more sperm release acrosomal enzymes thatmake a hole in the membrane of the egg, allowing one sperm cell to combinewith the egg. When the union of egg and one sperm occurs, the membraneof the egg instantly chemically changes, preven!ng other sperm frompenetra!ng the egg.4 / 4 ptsQues!on 19Which of the following is trueconcerning human cells?A. Haploid cells contain the full number of chromosomes (46). B. Diploid cells contain half the number of chromosomes (23). C. Gamete cells are haploid cells. Correct!Correct!D. A zygote has 23 chromosomes. E. A&B are true 0 / 6 ptsQues!on 20Your Answer:Discuss in detail the layers of cells (of the blastocyst) which form the embryo.The cells of the blastocyst form amnion, placenta, and the umbilical cord. The amnionis a sac filled with cluid to protect the fetus. The placenta the temporary organ thatprovides nutrients, respiratory, excretory, endocrine func"ons. And the Umbilicalcord a!aches from the embryo to the placenta.
