The mitochondrial DNA study indicated that there was no genetic input from Neanderthals in modern humans, but the whole-genome study suggests that in fact there was. Which of the following strategies could be employed to resolve this discrepancy?

A. Look at the Y chromosome because that
also does not undergo recombination.
B. Look at the X chromosome because that
also does not undergo recombination.
C. Look at genomic DNA only in modern
humans that are females.
D. Look at genomic DNA only in modern
humans that are male.

The human body's arterial blood pH is tightly maintained around 7.4 by buffering agents that bind hydrogen ions to stop any change in pH. If an acid-base imbalance overcomes the buffer system, the body changes the ventilation rate, or the rate at which gas enters or leaves the lungs. Changing the ventilation rate changes the concentration of CO2 in the blood, which alters the pH of the blood. In this case, pH 7.4 is the:

A. homeostatic challenge. B. sensor. C. effector. D. integrator. E. set point.
