Answer:
Gas exchange is crucial to sustain life because it rids the body of carbon dioxide and provides oxygen to the body.
Explanation:
Gas exchange in living beings is a mechanism that involves the incorporation of oxygen (O₂) into the organism and the elimination of carbon dioxide (CO₂). This exchange takes place in the pulmonary alveolus and in cells and tissues.
- <em><u>During respiration, the inspired air - loaded with O₂ - is exchanged with the CO₂ contained in the blood, taking advantage of the former and eliminating the latter during expiration</u></em><em>.
</em>
- <em>When the oxygenated blood is taken to the tissues, O₂ is passed to the cells, which are deprived of the CO₂ produced by metabolism.
</em>
The reason why gas exchange is crucial for the sustain of life is because it is the mechanism that allows the entry of O₂ necessary for cellular functions, as well as providing a means of CO₂ elimination.

Answer:
True.
Explanation:
The insulin and the glucagon are the two hormones that maintain the blood glucose level in the body. The insulin decreases the blood glucose level whereas glucagon increases the blood glucose level.
The lipolysis increases the blood glucose level level that works as the antagonistic to the insulin functioning. The levels of lipids start increases in the blood. To counteract this effect, the uptake of fat in body can cause disease like chronic liver disease due to the abnormal level of the lipids in the blood as well as in the liver.
Thus, the answer is true.
