Ammonium chloride absorbs thermal energy as it dissolves in water. Rodrigo designed an airtight, watertight pouch. He put a carefully measured amount of ammonium chloride in it. He added a measured amount of water to the ammonium chloride, sealed the pouch tightly, and then wrapped the pouch around a small bottle of water.

Rodrigo's device is intended to
bottled drinks. He can test how well his device works by measuring the total change in temperature of the
Next, Rodrigo should see if he can use the results of his test to improve the
of his design.

Which statement about the pancreas is not true? a. it is an endocrine organ in the abdomen. b. it release chemicals into the digestive system. c. it releases insulin to increase glucose levels. d. it release hormones into the bloodstream.

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).
