In endocrinology, the permissive effect can be defined as where one hormone can work in the presence of another hormone. Permissiveness is a type of biochemical phenomenon, in which the presence of one hormone is necessary to activate another hormone for its full effects on a target cell.

Expert Solution & Answer

Answer to Problem 1E

Correct answer :

Correct answer is option (d) Both a and c.

Explanation of Solution

Explanation/justification for the correct answer :

Option (a) effect of thyroid hormone on growth. The thyroid is a steroid hormone and it can bring out changes in the expression of certain genes. The thyroid hormone can promote the transcription of the gene involved in the production of the growth hormone. So, the secretion of the growth hormone cannot be done in the absence of the thyroid hormone. In this case, the thyroid hormone poses permissiveness for the growth hormone.

Option (c) effect of sex hormone on the secretion of growth hormone. The sex hormone helps in modifying and the growth-promoting effects of the growth hormone. Hence, the sex hormone has a permissive effect on the functioning of the growth hormone.

Option (d) given as both a and c. As the thyroid hormone and the sex hormones both have a permissive effect on the growth hormone, the option (a) and (c) are true. Hence, option (d) is the correct answer.

Explanation for incorrect answer:

Option (b) is given as the effect of insulin on glucose uptake by cells. It is not able to stimulate the formation of receptors for the hormone, like a permissive hormone. Hence, it is the wrong answer.

Option (e) is given as all of the above. As the insulin is not a permissive hormone, option (b) is incorrect. Hence, it is the wrong answer.

Conclusion

Thus, effect of thyroid hormones on growth and the effect of sex hormones on secretion of growth hormone, is an example of permissive hormones.

Use the following information to answer the question(s) below. Martin Wikelski and L. Michael Romero (Body size, performance and fitness in Galápagos marine iguanas, Integrative and Comparative Biology 43 [2003]:376-86) measured the snout-to-vent (anus) length of Galápagos marine iguanas and observed the percent survival of different-sized animals, all of the same age. The graph shows the log snout-vent length (SVL, a measure of overall body size) plotted against the percent survival of these different size classes for males and females. Survival (%) 100- 80- 60- 40- 20- 0+ 1.9 T 2 2.1 2.2 2.3 2.4 2.5 2.6 2.7 Log SVL (mm) 19) Examine the figure above. What type of selection for body size appears to be occurring in these marine iguanas? A) directional selection B) stabilizing selection C) disruptive selection D) You cannot determine the type of selection from the above information. 3

24) Use the following information to answer the question below. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (see table) and used to determine the actual allele frequencies in the population. TT 0.49 Tt 0.42 tt 0.09 Refer to the table above. Is this population in Hardy-Weinberg equilibrium? A) Yes. C) No; there are more homozygotes than expected. B) No; there are more heterozygotes than expected. D) It is impossible to tell.
