C. Osmosis
Explanation:
Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.
Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.
Osmosis is controlled to a large extent by concentration gradient.
Diffusion on the otherhand is the movement of molecules of a substance from one position to another.
Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.
Answer:
Cancer can develop anywhere in the body. It starts when cells grow out of control and crowd out normal cells. This makes it hard for your body to work the way it should.
For many people, cancer can be treated successfully. In fact, more people than ever before lead full lives after cancer treatment. The cells in our bodies all have certain jobs to do. Normal cells divide in an orderly way. They die when they are worn out or damaged, and new cells take their place. In cancer, the cells keep on growing and making new cells. They crowd out normal cells. This causes problems in the part of the body where the cancer started. They can also spread to other parts of the body.
