When an athlete completes a physical activity and sweats a lot, the kidney reacts to the loss of water by sweat by adjusting urine output causing the body to produce lower and more concentrated urine.
Answer: a. Increasing the surface area for diffusion
Explanation:
When the air is inhaled through the nostrils, the air containing the oxygen the air diffuses inside the alveoli. The alveoli are the tiny sacs where air enters and exchange of gases takes place. From the alveoli the oxygen enters into the blood stream. The oxygen is utilized by the cells for respiration. The increase in network and number of the alveoli will increase the surface area for the diffusion of oxygen and hence, will speed up the respiration process.
If your findings disproves your hypothesis then your hypothesis is probably wrong.
