B) vestibular ligaments
C) tracheal rings
D) vocal ligaments

Explanation:
A) The epiglottis is a flap of cartilage that covers the glottis during swallowing.

Because oxygen has a low solubility coefficient in water,
A. it is not easily dissolved in water and requires a steep partial pressure gradient to enter the water. B. it is impossible to dissolve oxygen into water unless the partial pressure gradient is very minor. C. it is easily dissolved in water and the partial pressure gradient is irrelevant to its solubility. D. it is easily dissolved in water and requires only a slight partial pressure gradient to enter the water.
Myasthenia gravis results from the destruction of acetylcholine receptors at the neuromuscular junction, but treatment involves medications that reduce acetylcholinesterase activity. Which statement best explains the effectiveness of these medications?
A. The antibodies destroy some but not all of the acetylcholine receptors, so reducing acetylcholinesterase activity increases the likelihood that acetylcholine will bind to the remaining receptors. B. The antibodies that destroy the acetylcholine receptors are less likely to work if acetylcholinesterase is present. C. Acetylcholinesterase is the substance that destroys the receptors as well, so reducing its activity increases the number of acetylcholine receptors. D. Acetylcholinesterase breaks down the acetylcholine to a substance that can bind to the damaged receptors.
