Peptide hormones are usually produced in the body ahead of the time when they will be required. They are usually synthesized in the inactive form and store in the secretory vesicles just under the plasma membrane. Stimulation of the signalling causes immediate release of these hormones into the surrounding medium or the blood. Thus, cellular response to a peptide hormone is always rapid compared to that of the steroid hormone.
Answer:
The answer is C
Explanation:
Habitat destruction is the most cause of extinctions. As deforestation continues in tropical forests, it causes mass extinctions among organisms.
All species have specific food and habitat needs. The more specific these needs and the more localized the habitat, the greater the vulnerability of species to loss of habitat to agricultural land, livestock, roads and cities. This is because the organisms are already adapted to the environment and any changes can prove disastrous for them.
In the future, the only species that survive are likely to be those whose habitats are highly protected, or whose habitat corresponds to the degraded state associated with human activity.

Though birth rates remain almost the same, but young population continues to grow because of the low death rate.
