Answer:

B) cAMP

Explanation:

Phosphodiesterase is an enzyme that breaks a phosphodiester bond, for example in molecules such as cAMP and cGMP. So, phosphodiestarases are  are regulators of signal transduction: regulate the duration of signaling pathway.

Caffeine is  central-nervous-system stimulant and the mechanisms of its action usually are: mobilization of intracellular calcium or inhibition of specific phosphodiesterases.

Write a paragraph explaining how genetic variation, reproductive strategies and environmental pressures have impacted the surviv
Andreas93 [3]

Answer: Genetics and Pressures

Explanation:

For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.

Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.

Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.

Which of the following statements is false? The inflammatory response can occur on the surface of the body and internally. Phagocytes are responsible for much of the healing that occurs with inflammation. Platelets release a growth factor that stimulates endothelial cells to divide, and the wound heals. Pus is produced during an inflammatory response that is inappropriately strong. Mast cells release propagandist, which are partly responsible for the pain of inflammation.
