Answer:
The correct answer is - facilitated diffusion.
Explanation:
Facilitated diffusion is a form of facilitated transport of molecules such as amino acid, glucose, and others through the plasma membrane involving the passive or indirect movement of molecules along their concentration gradient, which is led by the presence of another molecule normally a pore or channel made up of integral protein.
Facilitated diffusion depends on several factors such as the size of molecules, type of molecules, similarity of molecules to extracellular matrix or fluid that slow or fast the diffusion process.
Thus, the correct answer is - facilitated diffusion.
Answer:
Usually, parasites are much smaller than the host is, whereas predators could be either small or larger than the prey. Parasites have a very high reproduction rate but the predators reproduce slowly.

The three examples of stimulus include;
1. Hit the skin with a needle or pin is a good example of stimulus. The sudden removing of the hand is the response.
2. When somebody bangs a door you jump if you were unaware because of the sound. The jumping is the response to a stimulus.
3. Holding a hot plate we fling hand away from it. The stimulus here is holding the plate while removal of the hand is the response.
