What structure allows the hypothalamus to have direct communication with the anterior pituitary?
ANEK [815]

Hypophyseal portal system allows the hypothalamus to have direct communication with the anterior pituitary.

The hypophyseal portal system is a network of blood vessels that connects the anterior portion of the gland and hypothalamus at the base of the brain. Two capillary beds, one in the median eminence and the other in the anterior pituitary, make up the portal system. Its principal job is to swiftly transfer and exchange hormones between the anterior pituitary gland and the hypothalamic arcuate nucleus.

The cortisol, androgens, and aldosterone hormones interact with anterior pituitary gland cells via travelling through the hypophyseal portal system. Hormonal signaling through the hypophyseal portal system enables connection between these two structures.

What results when there is very heavy competition between two species??
BlackZzzverrR [31]
When there is heavy competition between two species these results may surface. First, even if there is just a little advantage of one species, the tendency is the best competitors will dominate the other. This may lead to the extinction of the weaker species. Another result is, competition may cause the traits of the competing species to evolve. This result is called character displacement. This is what happens when for instance the species live in the same area and have the same and common niche; the characteristics of the species evolve in order for them to minimize niche overlap. This is also for them not to have competitive exclusion. To add to that, when there is heavy competition, the finite resources will not be enough for all competitors who have all access to the resources. This may lead to very low survival rates.

Whale calves have a high survival rate, with most calves reaching adulthood. However, their aquatic ecosystem contains a limited
Masja [62]

Answer:

The second graph attached in the answer shows the survivorship of whales.

<span>
</span>

The whales follow the K-strategy of reproduction. Therefore, they will typically have a high survivorship. <span>K-strategy reproduction is the production of few offspring, but heavy investment in those offspring to ensure a better chance of survival. Humans for example, usually have one baby at a time, with a long gestation, and a long period of nursing babies and caring for children.</span>
