The lungs deliver a regular supply of oxygen to the blood, which is in turn circulated to most all the cells of the body. At the same time oxygen is consumed during aerobic cellular respiration within these cells. This implies that .

The correct answer would be - oxygen will passively diffuse into the cells.

Explanation:

As the oxygen molecules are very small and has no polarity or no charge they show the passive diffusion through the plasma membrane from the higher concentration to lower concentration inside the cell.

In the lungs the oxygen diffuses out the air sacs into the blood as the air sacs of lungs have higher concentration of oxygen than the blood stream and as the various cells perform the aerobic cellular respiration the concentration of the oxygen inside of the cell become low to the blood so oxygen diffuses into cells.

Thus, the correct answer is - oxygen will passively diffuse into the cells.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
