Answer 1

Answer:

Most plants respond to mechanical stimuli and those with rapid and highly noticeable touch-stimulus response have received much attention, such as the Venus flytrap (Dionaea muscipula Ellis).

Answer 2

Answer:

The stimulus in the scenario where a venus flytrap captures and traps an insect is the insect touching the trigger hairs.

Explanation:

A stimulus - in physiology and biology is defined as any detectable change in the environment of an organism.

This means that a stimulus is a change that an organism can detect in its environment.

For instance the stimulus in the venus flytrap is the presence of an insect touching on its sensing triggger hairs.

The ability of an organism to detect a stimulus is called sensitivity. In this case, the venus flytrap is sensitive to touch of its trigger hairs - an action that causes it to close trapping anything inside.

When the insect touches on its trigger hairs, the venus flytrap closes and traps the insect inside.
