How is the strength of a stimulus encoded by neurons?
A. by the size of action potentials B. by the frequency of action potentials C. by the duration of action potentials D. by whether the action potential peak is positive or negative
How does the renal countercurrent multiplier mechanism allow the creation of a concentrated urine?
A. It transports NaCl from the medullary interstitium into the collecting duct, which directly increases the osmolarity of the urine. B. It transports urea from the medullary interstitium into the collecting duct, which directly increases the osmolarity of the urine. C. By concentrating NaCl in the renal medullary interstitium, it allows water to be reabsorbed from the collecting ducts when vasopressin is present. D. By pumping NaCl and urea into the ascending limb of the loop of Henle, it raises the solute load, which turns into a concentrated urine once water is extracted from the collecting duct. E. When anti-diuretic hormone is present, it stimulates the pumping of NaCl from the medullary interstitium and water follows, concentrating the urine.
Which of the following is not true of the respiratory tract from the medium bronchi to the aveoli?

C) Proportionally, smooth muscle decreases uniformly. D) Lining of the tubes changes from ciliated columnar to simple squamous epithelium in the alveoli.
