Answer:
B is the right answer I think.
Answer:
A. depend on a concentration gradient
Explanation:
Simple and facilitated diffusion are the two methods of transport of substances down their concentration gradient. In both processes, substances are moved from the region of their higher concentration to that of their lower concentration. Since simple diffusion and facilitated diffusion are passive processes, there is no requirement of energy input to drive them. Both are driven by the concentration gradient of the substances only.
Viruses are considered non-living because they do not have a biological machinery to replicate, and they do not have a metabolism.
They replicate by using the host cell
Virus do not consume energy to survive or regulate its own temperature
