B, reproduce. It is not a living organism if it cannot continue their kind.
Answer:
Major difference between active transport and facilitated difusion is:
Active transport moves substances against the concentration gradient.
Facilitated diffusion moves molecules through the plasma membrane.
Explanation:
- Active transport involves the transport of molecules against the concentration gradient.
- Since molecules move from lower concentration to higher concentration this mode of transport needs energy.
- Facilitated diffusion do not require energy but need some other molecule or carrier protein to transport the molecules across the membranes.
- In facilitated diffusion, the molecules move from their region of higher concentration to the region of lower concentration.
Answer:
b
Explanation:
Internal respiration is the process of diffusing oxygen from the blood, into the interstitial fluid and into the cells.
