The correct answer is a. increased pCO2, decreased pH, decreased pO2.
<span>
Respiration is stimulated by high levels of pCO2 in the blood which are registered by chemoreceptors in the medulla of the brain. Because of the excessive CO2 in the blood, the pH is falling and when this occurs, the respiratory rate is stimulated to increase. In the condition of hypoxia, the chemoreceptors are more sensitive to O2 than to CO2. As the O2 levels in the body drop, the respiratory drive is stimulated.</span>

VARVARA [1.3K]

The answer is amygdala. This is the region of the brain that is responsible for emotional responses such as fear and anxiety. It is part of the limbic system and hence important in decision-making. It processes information and sends signals to the hypothalamus and other regions such as the locus coeruleus (that processes fear and panic as in this case).

Nuetrik [128]

Answer:

Angiotensin II and ADH (in high doses) ___Increases_________ peripheral resistance and blood pressure; and angiotensin II, aldosterone, and ADH ___Decreases_________ urine output to help maintain blood volume and blood pressure. ANP stimulates__volume receptors_____ , which decreases _peripheral resistance__________ and increases _in porasium serum_______ , which decreases blood ____volume________ . The net effect is a decrease in blood ____Pressure________

Explanation:

Angiotensin II is a powerful vasoconstrictor, greatly increasing blood pressure. It also stimulates the release of ADH and aldosterone, a hormone produced by the adrenal cortex. Aldosterone increases the reabsorption of sodium into the blood by the kidneys.

Atrial natriuretic peptide (ANP) is released in response to increased stretch in atria as a consequence of high blood volume and high blood pressure. The effect of ANP is to decrease both peripheral resistance and blood volume with a resultant decrease in blood pressure to within normal homeostatic limits.

Harrizon [31]
The answer is: contribute to ozone depletion.
CFC (chlorofluorocarbon), including freon, is used as the aerosol propellant. <span>An aerosol is a suspension in the gaseous form of solid or liquid particles. when these compounds reach the stratosphere, UV light affects them and they release chlorine atoms. Chlorine atoms are capable of breaking down ozone molecules. With fewer ozone molecules, the ozone layer becomes thinner and harmful UV light passes through it. </span>
