During the _____ phase of selye's theory of stress, considerable energy is expended to adapt to the stressor.

1 answer:

8 0

According to Selye's theory of stress, during the condition of the stress, the body undergoes the general adaptation syndrome, which occurs in three stages. These three stages are fight or flight, resistance reaction, and exhaustion.

The flight or fight reaction is stimulated by the hypothalamus. It results in the excitement of the sympathetic division of the autonomic nervous system. The resistance reaction is caused by the hormones released by the hypothalamus; this is long lasting and provides ATP (adenosine triphosphate) molecules for the counter reaction to the stress.

As the result of use of ATP and other energy resource from body during the resistance reaction, the body becomes deprived of energy. This causes the exhaustion in the body.

So, the resistance phase of the stress expands a considerable amount of energy, which causes exhaustion.

Heterozygous is another word for what?

tatyana61 [14]

Answer:

Heterojunction or having two identical alleles of the same gene.

Explanation:

A heterojunction is an interface that occurs between two layers or regions of dissimilar semiconductors. These semiconducting materials have unequal band gaps as opposed to a homojunction. It is often advantageous to engineer the electronic energy bands in many solid-state device applications, including semiconductor lasers, solar cells and transistors. The combination of multiple heterojunctions together in a device is called a heterostructure, although the two terms are commonly used interchangeably. The requirement that each material be a semiconductor with unequal band gaps is somewhat loose, especially on small length scales, where electronic properties depend on spatial properties. A more modern definition of heterojunction is the interface between any two solid-state materials, including crystalline and amorphous structures of metallic, insulating, fast ion conductor and semiconducting materials.

Lucia was a longtime smoker, despite the pressure put on her by friends and relatives to stop. when she was recently diagnosed w

alisha [4.7K]

The answer would be illegitimate

In the illegitimate sick role, there are stigmas that can be interpreted that the patient causes the disease to their self. In Lucia case, smoking is known to cause cancer and she was already warned by her friends and relatives to stop.
Her friends and relatives would think that she got the disease because of her choice, so she doesn't deserve the support or sympathy.

Is the concentration and the size of boxes the same at all locations on the map

skelet666 [1.2K]

According to a source yes.

This is because the determination of the size of the boxes in the same locations in the map have identical and intertwining figures that makes its visibility the same. Direction, legend, title and diagram have these influences of the shaping of the map.
