QUESTION 7 According to the instructor, human acclamatory (physical) adjustments are physiological responses to new conditions (which are reversible when those conditions change) alterations in the growth patterns of children aspects of technology which permit and promote survival genetic changes in population (inherited and non-reversible) all of the above QUESTION 8 According to the instructor, genetic adaptations (not "adjustments") in humans are another way in which human population change; such biological adaptations: are temporary and disappear when there is no longer a need for them are variations (due to mutations) on the basic body plan (they are not totally new structures) are actually caused by a change in a particular environment, and usually create a narrow biological adaptation all of the above none of the above

Explanation / Answer

#7 Ans: 1

Option one is best suited as the question is hinting towards physical acclimatization. Other available options such as alteration in growth patterns belongs to developmental acclimatization and genetic changes refers to genetic adaptations.

#8 Ans: 3

Genetic adaptations are mostly environmental specific. A particular type of genetic adaptation may be beneficial in one environment and might be the opposite in other environmental conditions.

#9 Ans: 4

An organism responds to varied changes in the environment by adjusting their behavioral, physical or biochemical traits. Thus, a decision taken to move out in sun is behavioral change and change in the skin color due to scorching heat is seasonal acclimatization.

#10 Ans: 3

Skin colour is a well-known adaptive trait.

#11 Ans: 1

Vasoconstriction, vasodilation and sweating are form of acclimatization as they are temporary adaptation to an environmental stressor and the responses becomes normal on removal of the stressor.

#12 Ans: 2 or 5

Expansion in thoracic cavity and increased lung capacity after long stays in higher altitude could be any of the two options available depending on the fact that if the changes are irreversible, the second option, acclimatization adjustments fits best and if the anatomical changes are more (or less) permanent it fits the developmental adjustments i.e., the fifth option given.
