Answer:

The effect that alcohol has on the brain.

Explanation:

Alcohol is one of the few substances that can get into contact with brain cells and affect them directly which results in behavioral change when exposed to too much alcohol.

The example given in the question is a result of that. Reynaldo acting very different than his normal self and becoming verbally abusive and showing agressive behavior is a sign that the alcohol is affecting his Frontal Lobe.

This is the part of the brain that is assigned with the control of very important functions such as emotional behavior, making decisions, language abilities etc. and when it is affected by alcohol, it can lead to unexpected emotional expressions such as fighting, crying etc.

I hope this answer helps.

Dmitry_Shevchenko [17]

Answer:

α = 0 if β= 0

Explanation:

If both species want to persist in the same environment and their niches are also over lapping then both of the co-efficient values should be equal. There are two possibilities on these values for persistence. One is that one should compromise to the change produced by the invasive specie and two is that the new specie should compromise if he wants to stay (<em><u>Assuming that there is no competition</u></em>). In this way their niches won't overlap to a greater extent and therefore better chances of survival for both.

The proper function of the cardiovascular system relies on blood following the correct pathway through the heart. Valves within
Nadya [2.5K]

Answer:

The Mitral/Bicuspid Valve

Explanation:

The heart is composed of 4 chambers: left and right atria, and left and right ventricles. The “right heart” (right atrium and ventricle) receives deoxygenated blood from the systemic circulation through the Vena Cava, and impels this blood towards the lungs through the Pulmonary Arteries where it will be oxygenated. The “left heart” (left atrium and left ventricle) receives oxygenated blood from the pulmonary circulation through the Pulmonary veins and impels this blood towards the systemic circulation through the Aorta artery.

The systemic and pulmonary circuits work in series, and maintaining the unidirectional course of the blood flow is very important. This can be done by the presence of fibrous valves that are present between the atrium and the ventricles, and in between the ventricles and the Pulmonary/Aorta artery.

The location of these structures are as follows:

Systemic circulation ⇒ Right Atrium → [Tricuspid Valve] → Right Ventricle → [Pulmonary Valve] → Pulmonary Artery ⇒ Pulmonary circulation

Pulmonary circulation ⇒ Left Atrium → [Mitral/Bicuspid Valve] → Left Ventricle → [Aortic Valve] → Aorta ⇒ Systemic circulation
