Question

A mouse sees a hawk fly overhead. The mouse then runs into the nearest hole in the ground. What is the hawk flying overhead in this scenario?
a)a stimulus
b)a response
c)a developmental change
d)a unicellular organism

Answer 1

a) a stimulus

The hawk flying overhead is the stimulus. The mouse running to the nearest hole is the response to the stimulus.

It's obviously not a one-cell (unicellular) organism.

A developmental change is something changes because an organism is growing. Example: A tadpole going through developmental stages to change into a frog. So that answer is incorrect as well.
