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.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
