Question
Chapter 49, Problem 3ITD
Summary Introduction
To review:
Whether the given data support the hypothesis that living near farmlands can affect male reproductive function adversely. The data is as follows:
Introduction:
The male reproductive system functions under optimum conditions. Any imbalances in hormones, ions, and other essential chemicals that contribute to the system would adversely affect it. A common example is an exposure to pesticides and other chemicals involved in agriculture that affect the fertility of males.

Which of the following statements correctly identifies the differences between spermicidal jelly and a condom?
Select one:
a. Condoms are semipermeable membranes whereas spermicidal jelly does not form any barrier.
b. Condoms contain an antibacterial coating while spermicidal jelly only kills sperm cells.
c. Condoms form a barrier to protect against sperm movement as well as viruses. Spermicidal jelly breaks down cell membranes of bacteria.
d. Condoms prevent the physical transfer of most sexual secretions. Spermicidal jelly kills sperm, but allows fluid transfer.

3. Several factors are listed below. Determine which of the factors will increase the variation in a population.
A.Several factors are listed below. Determine which of the factors will increase the variation in a population.
B.During mitosis, the parent cell divides and that increases the genetic variation in a population.
C.During m, chromosomes are copied, which creates variation.
D.During mitosis, mutations can change the DNA and that creates variation within species.

- Researchers are learning how to transfer sperm-making cells from fertile male mice into infertile male mice in the hopes of learning more about reproductive abnormalities. These donor spermatogonia cells have developed into mature spermatozoa in 70% of cases, and some recipients have gone on to father pups (as baby mice are called). This new advance opens the way for a host of experimental genetic manipulations. It also offers enormous potential for correcting human genetic disease. One potentially useful human application of this procedure is treating infertile males who wish to be fathers. a. Do you foresee any ethical or legal problems with the implementation of this technique? If so, elaborate on the concerns. b. Could this procedure have the potential for misuse? If so, explain how.arrow_forwardHow can PID (pelvic inflammatory disease) lead to infertility in women? Select one: a. PID can lead to scar tissue developing on the Fallopian tube. This prevents the egg and the sperm from meeting, causing infertility. b. PID prevents the endometrium from forming. There is not enough material for the fertilized egg to implant itself. c. PID leads to scar tissue on the corpus luteum. This disrupts ovulation. d. PID affects the cervix. This causes the cervix to swell, decreasing the chance a sperm could pass into the uterus.arrow_forwardA variety of fertility tests are available for women to purchase overthe counter—for example, at drugstores. Because more women nowdelay their first pregnancy until they are older, these tests arebecoming more popular. Many of these tests incorporate antibodiesthat specifically react with hormones found in a woman’s urine.What specific hormones could be measured in these tests, and howmight these tests actually work?arrow_forward
- Binary fission is a form of asexual reproduction. What is an advantage of asexual reproduction when compared to sexual reproduction? a Asexual organisms are less likely to have mutations in their DNA than sexual organisms are. b An organism that reproduces asexually can reproduce much more quickly than an organism that reproduces sexually. c An asexual organism lives longer than an organism that reproduces sexually. d An organism that reproduces asexually is better equipped to respond to environmental changes than an organism that reproduces sexually.arrow_forwardWhich description below explains how the hormones released in birth control pills causes natural ovulation to cease? Select one: a. Birth control pills release estrogen. Estrogen controls the secondary sex characteristics of the female body. b. Birth control pills release progesterone. Progesterone feeds back to the pituitary gland, thereby inhibiting FSH and LH and in effect, stopping the ovarian and menstrual cycle. c. Birth control pills release progesterone. Progesterone causes an increase in FSH, thereby increasing the production of follicles. d. Birth control pills release estrogen. Estrogen feeds back to the posterior pituitary, causing an increase of LH and thereby ceasing the ovarian cycle.arrow_forwardBesides the Warrior gene, the only other genetic mutation directly correlated with “super-maleness” and violence is an extra Y chromosome at birth.

Group of answer choices -True -Falsearrow_forwardWhich of the following is a advantage of asexual reproduction? a.)Same DNA being passed down-NO GENETIC VARIATION IN THE OFFSPRING b.)If parent has genetic disease offspring will have it too c.)Only one parent involved. No searching for mates d.)Requires more cellular energyarrow_forward
- Please answer the attached questionarrow_forwardWhich of the following is a disadvantage of sexual reproduction? a.)Offspring can be reproduced more quickly than by sexual means b.)Two parents are required for making sex cells c.)Offspring are genetically different d.)Genetic diversity makes organism respond uniformly to environment changesarrow_forwardBirth Defects and Multiple Births A woman who carries multiple offspring at the same time increases the risk of some birth defects. FIGURE 42.18 shows the results of Yiwei Tang's study of birth defects reported in Florida from 1W6 to 2000. Tang compared the incidence of various defects among single and multiple births. She calculated the relative risk for each type of defect based on type of birth, and corrected for other differences that might increase risk such as maternal age, income, race, and medical care during pregnancy. A relative risk of less than 1 means that multiple births pose less risk of that defect occurring. A relative risk greater than 1 means multiples are more likely to have a defect. FIGURE 42.18 Prevalence, per 10,000 live births, of various types of birth defects among multiple aria single births. Relative risk for each defect is given after researches adjusted for the motor's age, race, previous adverse pregnancy experience, education, Medicaid participation during pregnancy, as well as the infant's sex and number of siblings. 4. Does a multiple pregnancy increase the relative risk of chromosomal defects in offspring?arrow_forward
