We breathe more quickly and deeply when we exercise. Why does this make sense? Select all that apply. a) Because when we exercis
storchak [24]

Answer:

a) Because when we exercise, we hydrolyze more ATP to ADP and Pi, and O2 is necessary for the hydrolysis, so we increase our intake of oxygen.

c) Because when we exercise, we produce more CO2 and increased ventilation is necessary to rid ourselves of CO2.

d) Because when we exercise, we use more ATP, and additional O2 is necessary to generate sufficient ATP.

Explanation:

During exercise , our body needs more energy in the form of ATP. This ATP comes from break down of food materials in the mitochondria of the cell during cellular respiration. With the addition of oxygen, more ATP is produced during respiration and this ATP is used by the body. With ATP, carbon dioxide is produced as a waste material which can be removed by exhaled out during breathing.

Explain why an increase in CO, in Earth's atmosphere, might cause the temperature of the atmosphere to increase and lead to clim
ICE Princess25 [194]

Answer:

When the carbon dioxide concentrations rise, the air temperature will rise as well due to the greenhouse gases heating up and multiplying.  

Explanation:

Carbon dioxide causes about 20 percent of Earth's greenhouse effect; water vapour accounts for about 50 percent; and clouds account for 25 percent. ... Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapour evaporates into the atmosphere—which then amplifies greenhouse heating.
