Answer:
The immune system works like what happens when a prisoner is breaking out of their cell. The Cell Mediated Response in the immune system is when killer t-cells attack any cell that has a pathogen on it. In this analogy, the cell-mediated response is the orders given by the police officer.
Explanation:
Answer:
D. They release waste into the bloodstream.
Explanation:
Kidneys are the primary organs of the excretory system. Their primary function is to remove the metabolic waste from the blood and release it out of the body in the form of urine. The nitrogenous waste, drugs, uric acid, and other metabolic waste products are removed from blood in kidneys.
Hence, kidneys do not release the waste into the bloodstream, rather release them out of the body and filter the blood.
The term is Facilitated diffusion.
Facilitated diffusion is a transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell's energy, and because it does not use the cell's energy, it is a passive transport.
The energy is provided by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell.
The carrier proteins of the GLUT family are responsible for transporting glucose. They bind to glucose , which causes them to change shape to fit in the membrane passage then they translocate the glucose molecule from one side of the membrane to the other.
Red blood cells use facilitated diffusion to absorb glucose.
