Answer:
<h2>Facilitated diffusion
.</h2>
Explanation:
1. Diffusion: it is the net passive movement of particles from higher concentration to lower concentration. Diffusion continues until the concentration of substances is equal through out.
2. Facilitated diffusion: is the process of passive transport of molecules or ions across a biological membrane and requires (via) a specific carrier protein.
3. Facilitated diffusion is passive type and require specific protein and it requires no energy from the cell.
4. It requires specific proteins through which molecules move from one side to another.

Negative feedback reverses a change in a variable that has moved outside of its normal range, whereas positive feedback strengthens it.
Feedback loops do not only apply to blood pressure. There are many examples from body temperature regulation to child birth to your AC unit at home.
Answer:
The derived unit of pressure is newton per metre square (Pa). It is a derived unit because it's obtained by adding two or base quantities.
The symbol is Pa and the expression in terms of SI base units is m-¹kgs-²
