a. Uric acid is a much simpler molecule.
b. It takes less energy to make uric acid.
c. Less water is required to excrete uric acid.
d. More solutes are removed excreting uric acid.

How would damage to the renal capillaries resulting in an increase in protein filtration and urinary excretion affect net filtration pressure in the systemic circulation?
a. Increase capillary reabsorption due to an increase in interstitial colloid osmotic pressure
b. Increase capillary filtration due to an increase in interstitial hydrostatic pressure
c. Increase capillary filtration due to a decrease in blood colloid osmotic pressure
d. Increase capillary reabsorption due to increased blood hydrostatic pressure
Why are humans not able to meet their water requirements by drinking seawater? Assume seawater has a concentration of 1400 mOsM. In your explanation, consider both the renal system and the digestive system. Additionally, describe the physiology of two symptoms of excessive seawater consumption that occur prior to death.
