Answer:

The rate of gaseous exchange in alveoli and blood depends on the difference in pressure of gases in both the alveoli and blood capillaries.

Explanation:

The air in alveoli has high pressure of oxygen and low pressure of carbon-dioxide.

The air in blood vessels has high pressure of carbon-dioxide and low pressure of oxygen

Due to the diffusion, the oxygen from alveoli moves towards to blood capillaries and carbon-dioxide diffuses from blood to alveoli.

xz_007 [3.2K]

Answer:

frontal

Explanation:

In a mammalian brain, there are four major lobes that are present and one of them is the frontal lobe.
The frontal lobe is mainly rich in dopaminergic neurons and thus, it is mainly concerned with functions such as memory, reward, motivation, planning, attention, etc.
The process of break down of tissues and cell death in the tissues is referred to as atrophy and since the frontal lobe is associated with the functions as mentioned above its atrophy would lead to a slow decline in these functions.
Since Mr. Klondlike behavior is changing his blunt comments are most likely a result of atrophy of the frontal lobe.
