Please I need help with these Questions. Iam not sure about my answer and please I need some explaining. chance to shine-get that 100%!! True/False section Please correctly identy6 each o the following statements as true or false. Mark "a" true and "b"for false. Impotence means that a male cannot produce "normal or physiologically active" spermatozoa Maternal blood mixes directly with fetal blood within the placenta during nutrient actually 2. exchange. Both males & females can achieve multiple orgasms if sexual stimulation is maintained or continued beyond the initial orgasm. ovulated oocytes secrete allurin which functions as a a chemotaxie attractant for spermatozoa. Females, like males, continue to produce new gametes throughout life just far less numbers of them. In Prophase I of Meiosis, chromosome pairs line up and can exchange large pieces of DNA in a process called "crossing-over" increases the variability of Humans are the only species that use sexual intercourse for more than the production of offspring 8. of the oocyte by a sperm results immediately in a "wave of depolarization" the cell around the oocyte knocking off any other spermato is called a "Fast Block" to polys spreads A developing female fetus retains mesonephric tubules (wolffian ducts) for her reproductive ducts. 10. Pregnancy is maintained initially by bcG uman chorionic gonadotropin) keeping the Corpus luteum viable and actively secreting progesterone until the placenta can take over. 11. L The largest component of semen is the nutrient secretion (fructose, etc.) from the seminal vesicles. 12. ovulation results from a mid-cycle surge of FSH (Follicle Stimulating Hormone). 13 PSNS mediated release of nitric oxide causes an increase in blood flow into corpus cavernosa bodies within the shaft of the penis creating pressure that essentially closes off venous drainage and makes the penis rigid or erect. Tui, T 14 E Afemale oocyte remains in a state of "suspended animation" (stuck in Metaphase m and will not finish the process of Meiosis unless fertilized by a sperm. Is e In order to survive, a developing embryo must digest its way into the endometrial lining of the uterus in a process called Implantation. T 16. The external genitalia of both genders is identical for almost the first trimester of development. 17. The processes of Capacitation that beg in the epididymis "teaches" sperm sperm. to behave like 18. r circumcision is simply the surgical removal of the foreskin (prepuce) from glans penis the 19. T The process of Meiosis produces 4 haploid daughter cells that are exactly genetically identical. l 20 spermatic cords & Dartos muscle in the wall of the scrotum play a TT critical role in maintaining a cooler temperature in the testes for appropriate spermatogenesis.Explanation / Answer
1. False. Impotence is not related to sperm production, but it is the inability in male to maintain erection.
3. True. Both can attain multiple orgasm by clenching of PC muscles.
14. True.Secondary oocyte remains in a state of metaphase II throughout the ovulation process and till the fertilization occurs.
16. True. For the first few weeks of development, the genital organs remains same in both sexes.
19. True. Four haploid daughter cells have identical genetic information.
20. True. Cremaster and Dartos muscles controls the temperature regulation of testes.
