A team of researchers hypothesizes that some snake species have a sense of smell sensitive enough to track individual prey animals based on minute differences between similar individuals.
Which finding, if true, would most strongly support the team's hypothesis?
- A
Some snakes are active at night.
- Bcheck_circle
Snakes presented with scent trails from two genetically similar prey individuals consistently followed the trail of the specific individual associated with a recent feeding.
- C
Snakes use their tongues to collect chemical cues from the air.
- D
Many snake species are predators of small mammals.
Explanation
A demonstrates discrimination between similar individuals based on scent and prior association, exactly the hypothesis. B, C, and D are general facts.
