Which is an example of a stimulus and the accompanying response of an organism?
question 2 options:

a hawk grabs a branch to gain a perch.

a rat scurries past, and a python strikes at it.

a wildebeest crosses a river during migration.

an earthworm burrows into new, rich soil.

The correct option is B) A rat scurries past, and a python strikes at it.

Explanation:

A stimulus can be described as any thing or event which is detected  as a signal and a response is generated by the body of the organism for that signal. In the scenario discussed in option B)The passing of the rat acts as a signal for the python. In response to the signal, the python generates a response by striking the rat. Hence, it is an example of a stimulus and the accompanying response of an organism.
