Answer:
The activity of cyclic AMP phosphodiesterase is prevented by caffeine. The caffeine prevents further dissociation of cAMP, which eventually increases the response within the body. The activity of neurotransmitters, that is, of noradrenaline or epinephrine, gets increased due to enhancement in response.
This further enhances the activity of the heart, the rate of muscle contractions, blood pressure that further helps in delivering more oxygen to the brain, and other parts of the body. Thus, the inhibition of the enzyme cyclic AMP phosphodiesterase helps the athletes to prevent the wall.
Answer:
B. Directional selection
Explanation:
When natural selection starts to choose one phenotypes that is an extreme (as in, a really small neck or a really long neck), this is an example of <u>directional selection.</u> It makes sense for giraffes to have evolved this way, because the longer the neck, the more ably they can eat food from high branches. The more food they could get, the more chance of reproduction, the more "evolutionarily fit" they are.
Stabilizing selection is when national selection picks average phenotypes (like a medium-sized neck). Disruptive selection is when the extremes are both picked (like all the medium-sized neck giraffes die, and two different species start to emerge). Sexual selection is picking a mate based on traits. Clearly, those answers don't work here.

Answer:
"Location 4" indicates a low-pressure area
Explanation:
A low-pressure area is defined as the region in which the pressure in the atmosphere is comparatively lesser than nearby surrounding areas. This region is a depression that is comprised of more winds, warmer air, and lifting of air mass takes place.
In a low-pressure zone, the warm air becomes less dense, due to higher temperature, as a result of which it rises up into the atmosphere. As it rises up into the atmosphere, it eventually cools and condensation starts taking place. After a definite period of time, rainfall occurs.
Thus, in the given image, location 4 shows the low pressure area.
