Chapter 53, Problem 4A
Summary Introduction
Introduction:
The pregnancy results after the fertilization of male and female gametes. During pregnancy, the female experiences the change of hormonal level. The sudden increase of progesterone and estrogen helps in maintaining the pregnancy and also helps in the development of the fetus inside the mother’s womb. During pregnancy, the other hormones like prostaglandin and oxytocin level also increases, which helps with the delivery of the fetus.

- What selective forces might limit the stage of development at which humans are born?arrow_forwardIn an experiment described in lecture, a portion of tissue containing ZPA was transported to the anterior side of a limb bud. Limb development was compared in this limb bud compared to a limb bud in a chick with a single ZPA on the posterior side of the limb bud. What is the independent variable in this study? Group of answer choices A. the structure of the resulting limb buds B. the number of ZPA C. the number of limb buds D. the movement of the ZPA E. the size of the resulting limb budsarrow_forwardWhich statement about menopause is most correct? A. Menopause has to be adaptive because life-history theory predicts that women should not outlive their reproductive capacity, so menopause must have some function. B. Menopause has to be adaptive because humans, not chimpanzees, experience menopause, and humans are evolutionarily more advanced than chimps. C. Several hypotheses for menopause as an adaptation have been proposed, but more evidence is necessary to support any one of them. D. Several hypotheses for menopause as an adaptation have been proposed, but they have not been tested.arrow_forward
- Some uninformed people might argue that studying the development of an obscure little fish like the threespine stickleback is a waste of time and money. Why would biologists study the genes that control development in stickleback fish? Give some reasonsarrow_forwardHow does the production of sperm differ from the production of eggs? a. Sperm production involves meiosis, whereas egg production involves only mitosis. b. Meiosis during sperm production produces four sperm cells, whereas meiosis during egg production produces only one functional egg cell. c. Sperm are haploid, whereas eggs are diploid. d. Sperm production begins during fetal development, whereas the meiotic process that begins egg production doesn’t begin until pubertyarrow_forwardIs this true or false? a. Fertilization is followed by a cleavage, a period of rapid cell division without growth. b. From the process above, this results in the production of a large number of cells called blastomeres. c. In sexual reproduction, the offspring have the same combinations of genes as their parents. d. Sequential hermaphroditism occurs when an animal is one sex during one phase of its lifecycle and the opposite sex during another phasearrow_forward
