What factor is a characteristic of passive transport?

1 answer:

8 0

Answer:

In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.

It occurs without energy input. Passive transporters let something across a membrane "with the gradient" in other words, substances travel from high concentration to low concentration, which is energetically favorable.

Sonja [21]

Answer:

Phagocytosis in the inflammatory response

Explanation:

In the given question, the person is injured and is bleeding. This injury initiates the inflammatory response, a type of immune response to the injured site.

This inflammatory response recruits the defensive cells flowing in the blood called white blood cells to the injured site.

The white blood cells interact with these foreign bodies and may help eliminate foreign material.

One of the mechanism by this response is the phagocytosis which occurs when the monocyte WBC interact with the pathogen and engulf and degrade it.

Thus, Phagocytosis in the inflammatory response is correct.
