Question

1. someone might not feel well after riding a fast elevator in a tall building due to over - stimulation of

a. photorecptors
b. the semi - circular canals (rotational equilibrium)
c. chemoreceptors
d. the utricle and saccule (gravitational equilibrium)
hint: motion sickness is linked to over - stimulation of the semi - circular canals (midway rides, car rides on curved roads, car sickness, etc.).

Explanation:

Motion - sickness from elevator rides is due to over - stimulation of balance - sensing organs. The semi - circular canals deal with rotational equilibrium and can be over - stimulated during rapid elevator movement, causing discomfort. Photoreceptors detect light, chemoreceptors detect chemicals, and the utricle and saccule are more related to linear acceleration and gravitational equilibrium rather than the rotational aspect relevant here.

Answer:

B. the semi - circular canals (rotational equilibrium)
