A dietician asks a patient about the food that the patient eats and makes the table below to summarize the results. Macromolecule
Suggested percentage of diet
Actual percentage of diet
Carbohydrates 45–65% 70%
Lipids 20–35% 5%
Proteins 10–35% 25%

Based on the table, what advice do you think that the dietician will give the patient?
The patient should increase the amount of lean meats (proteins) and decrease the amount of oils in his or her diet.
The patient should decrease the amount of lean meats (proteins) and increase the amount of oils in his or her diet.
The patient should decrease the amount of rice and pasta and increase the amount of oils in his or her diet.
The patient should decrease the amount of rice and pasta and increase the amount of lean meats (proteins) in his or her diet.

Why do we perceive objects as retaining their brightness under different lighting levels?

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i.e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).
