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.

ANSWER: MITRAL VALVE STENOSIS

EXPLANATION:

The child have the risk of having MITRAL VALVE STENOSIS. It is also referred to as mitral stenosis.

Mitral valve stenosis occurs as results of the mitral valve opening narrowing. Which effect to less blood flowing through it.

The mitral valve is located between two chambers (the atrium and the ventricle) on the left side of your heart.

However, Mitral valve stenosis can lead to different health issues, including blood clots, difficulty breathing, fatigue, and heart failure.

Mitral valve stenosis is specifically caused by rheumatic fever (a childhood disease). This rheumatic fever occurs has a result of the body's immune response to an infection associated with the streptococcal bacteria.

Acute rheumatic fever affects the joints and the heart greatly. It causes joints inflammation temporarily and in severe case causes chronic disability.

Nevertheless, this cardiac complication have treatment and it is based on whether the affected individuals shows symptoms. Medications like blood thinners or anticoagulants (to reduce the risk of blood clots), diuretics, antiarrhythmics (to cure abnormal heart rhythms), beta-blockers (to slow your heart) etc, are being administered based on the level of the complication.

BaLLatris [955]

<h2>Vascular and Nonvascular Plants </h2>

Explanation:

Kingdom Plantae on the basis of vasculature is divided into two groups-vascular and non-vascular plants .

<u>Vascular plants </u>or tracheophytes have a proper tissue-level organization and true shoot and root structures like leaves, stem, flowers, root etc
The tissue system or vasculature of vascular plants compromises of vascular tissues like tubular vessels – xylem and phloem

The xylem transports nutrients to various parts of the body from the leaves.
Phloem conducts water and other nutrients from the roots to various parts of the plant .

These are flowering plants that include the phanerogams – angiosperms and gymnosperms and bears flowers and fruits like the cedars, pine, clubmosses, lilies, sunflower etc.
Dicots are with tubular vasculature.

Non-vascular plants or bryophytes with an absence of proper tissue-level organization and true shoot or root systems
<u>Nonvascular plants</u> are small. Their transport mechanism is poor due to lack of vascular tissues
These plants are lack proper shoot or root system.
It includes mosses, hornworts etc.
Monocots are plants with scattered tube-like vessels .
