Answer:
To produce ATP.
Explanation:
Our cells do cellular respiration in order to produce energy molecules in the form of ATP after break down of glucose molecules. This energy is used ifor different activities. in cellular respiration, more number of ATP are produced in aerobic respiration as compared to anaerobic respiration which produces less number of ATP molecules. Our cells are not on fire because of the production of very low amount of ethanol which is 3g.
Answer: B. pressure changes in the thorax
Explanation:
The veins are the blood vessels which returns the deoxygenated blood from all the tissues and cells of the body back to the heart. The ventricular systole, venous valves, activity of the skeletal muscles and neural control over venoconstriction all influence the movement of the blood in the venous.
The pressure changes in the thorax occurs due to inspiration and expiration. During the process of inspiration, the diaphragm below the lungs contracts and moves downward while the muscles of the ribs pulls downward. When the size of the thoracic cavity increase the air pressure inside the cavity decreases and vice-versa. The pressure inside the thoracic cavity is not related with the movement of the venous blood as it regulates the exchange of the gases not the blood.

You can find biodiversity anywhere that there is a variation of life, whether it be genetic, species, or ecosystem variation. Coral reefs are a great example of ecosystem biodiversity. Rainforests are a great example of species biodiversity.
