Question

snakes flick their tongues because they
a are frightened.
b taste odors in the air.
c want to uncoil quickly.
d want to threaten intruders.
click the button or type the let

Explanation:

Snakes lack a well-developed sense of smell via nostrils alone. Flicking their tongues collects odor particles from the air, which are then transferred to the Jacobson's organ (a sensory structure in the mouth) to detect and analyze scents, helping them navigate, find prey, or avoid predators.

Answer:

B. taste odors in the air.
