About comparison and differences between response and adaptation using daily activities of humans or organisms around humans.
Introduction:
The response is defined as a mechanism in which different reactions occur in the body of an organism whenever it receives any kind of trigger or stimuli from the external or internal environment.
Adaptation is the process in which some traits or features are permanently acquired by an organism and are passed down from one to the next generation.
Explanation of Solution
Response and adaptations are the two different phenomena that help an organism to survive or adjust to the environment it lives in. In humans, different examples that compare these two phenomena are as follows:
Goosebumps: It is the state when there occur bumps on the skin or straightening of body surface hairs in conditions of fear or sexual arousal. Goosebumps occur involuntarily in uneasy or pleasurable conditions. During earlier times, humans used to have long body surface hairs, and the straightening of these hairs in fearful conditions would scare away the enemy. Nowadays, humans have very small or no body hair as now humans live in a well-organized society and have other means to get rid of the enemy. Shortening of hair is an adaptation in humans as long hairs are not required.
Melanin production: Melanin is a pigment that is produced in the body of humans to protect the skin from sun damage. Early ancestors of humans used to have large amounts of melanin in response to the climate they live in. With time, humans have adapted to different environmental conditions or climate they live in, and thus the amount of melanin also varies among humans.
A response is something that an organism performs instantly to any stimuli and examples of this include Goosebumps and melanin secretion. Adaptation is something that an organism has acquired and is not an instantaneous effect. It occurs slowly over a span of years.

- Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…arrow_forwardQuestion #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:arrow_forwarda. What percentage of a drug is eliminated after 4 half-lives?

- If you wanted to reduce the difference between peak and trough levels that occur with repeated administration of a drug, how would you adjust the dose and dose interval without changing the plateau concentration (plateau is the average of peak and trough levels)? Select your answers for both dose and interval. Hint: It may be helpful to think about this problem using an example such as food. How would you eat if you wanted to maintain very steady hunger/satiety levels without changing your total caloric intake? Options: A. Dose; Increase dose B. Dose; Decrease dose C. Dose; Do not change dose D. Interval; Increase the interval between doses (give the drug less frequently) E. Interval; Decrease the interval between doses (give the drug more frequently) F.
