According to the evolutionary perspective of mate selection, why do men and women exhibit different preferences in mate selection?
a.

b.
each gender has differing societal expectations and restrictions.
c.
each gender has differing attraction cues and priorities.
d.
each gender has differing innate social capabilities.

The correct answer is option B, Each gender has differing societal expectations and restrictions.

Explanation:

Unlike animals who choose their mates on the basis of natural selection (attraction due to some physical feature etc.) , humans adopt more social approach towards their mate selection. Since humans are social animals , their choices of mate get affected by social factors such as money, health, power , family background etc. In some countries, a female prefer a financially well settled man over the others.

explanation:

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
