olya-2409 [2.1K]

Answer:

cAMP, IP3, cGMP, DAG and cAMP are the second messengers.

Explanation:

The extracellular factors act as the first messengers. These are usually hormones and neurotransmitters. The neurotransmitters like serotonin, growth hormone and epinephrine. The second messenger depends on the signals received by cell surface receptors. The cAMP, IP3, cGMP, DAG and cAMP are the second messengers. The secondary messenger target molecules present in nucleus and cytoplasm.

The signal information is transduced into cellular responses in the cytoplasm and nucleus with the change in receptor. This leads to the activation of signaling cascade.

Explain how seasonal changes in carrying capacity can account for the annual cycles in population size observed for this populat
murzikaleks [220]
<span>Carrying capacity is how many animals a given location can hold. This means that if the number of rabbits, n, exceeds the carrying capacity, C, then the difference between the number of rabbits minus the carrying capacity (n - C) will likely die to starvation. Seasons in Ohio can directly affect carrying capacity because colder weather usually means less food. Rabbits can eat plants as well, and in winter, plants do not do well to survive. Thus, the carrying capacity will decrease. In contrast, in summer, plants flourish so the carrying capacity will increase.</span>
