because if they didnt get replaced then you would lack the cells.
and you would die. i think.
Cells age, wear out and die. If they weren't replaced, we'd die, a lot sooner than we do today.
They wear out is the main reason. You shed millions of skin cells every day.
Fruit is the main defense against viruses because it gives you nutrients
The primary function of the cardiovascular system is transport. It can be thought of as the highway system of the body with the veins and arteries being the highways and main roads, the capillaries as the small streets and driveways. Then the cars, SUVs, and trucks are the red and white blood cells and platelets.
to get a better job
Oxygen is carried around our body by blood cells. These are little particles like sand which make up the blood we see. There are also white blood cells which helps us get rid of unhydenic things in our body.
the plant cell is round and the animal cell is squered

MACROPHAGES
release energy
The main function of meiosis is to produce gametes, which are the egg and sperm cells. These cells have half of the number of chromosomes that are in a normal body cells.
lollies
The main function of specialized cells serve different tasks which include moving oxygen throughout the body, killing bacteria, removing mucus from the body, etc. Examples of speciazlized cells are white blood cells, red blood cells and muscle cells.
It sounds like the main switch is malfunctioning and it should be replaced.
carrying oxygen to the body.
blood in the body carries oxygen to the cells...
No. The main reason is that viruses are not really alive, the way you and I think of it. Drugs like Interferon, which occur in the body's cells and as a manufactured drug, do not "kill" viruses, but rather block the virus's ability to grab hold of and infect your body's receptor cells.
its to give the body energy its the main source of energy in cells in humans and mainly animals
Red cells do not directly protect the body, as their main and only task is shipping oxygen and carbon dioxide to and from the body parts so they can function. White cells are the ones that do the job of fighting intrudes to the body.
