In times of stress the sympathetic nervous system stimulates the adrenal medulla which then secretes catecholamines. The catecholamines includes; Dopamine, epinephrine and norepinephrine. Catecholamines are made by nerve tissue, the brain, and the adrenal glands. They help the body respond to stress or fright and prepare the body for "fight or flight" reactions.
In homo sapiens(humans), males are the heterogametic sex meaning their sex chromosomes are not the same(=XY) while females are homogametic(=XX).
Sex linked traits or x linked traits are traits whose genes are present on the X chromosome. So if there is a recessive mutation in those genes, males will express that recessive trait. Basically males express everything that’s on their X chromosome because they only have 1, but females have 2 which helps “hide” the mutation and to not express the particular recessive trait.
That is why sex linked traits are more evident in males in the population and an example of that would be colorblindness.

A. A farmer crosses two kinds of corn. He produces a new, better tasting type of corn.
Answer:
B. 0 m
Explanation:
From the position - time graph, the object would have traveled a distance of 0m after 6s.
The graph shows a decrease in distance traveled with increasing time.
- the y - axis is the position of the body
- the x - axis is the the time taken
If we trace up the time taken to the curve, the position will be 0m.
Therefore, the position of the body after 6s is at 0m.
