Chemotherapy is a drug treatment that uses powerful
chemicals to kill fast-growing cells in your body.
Chemotherapy is most often used to treat cancer,
since cancer cells grow and multiply much more
quickly than most cells in the body. It targets cells that

radiation or surgery, which target specific areas,
chemo can work throughout your body. But it can also
affect some fast-growing healthy cells, like those of
the skin, hair, intestines, and bone marrow.

many monomers linking together, forming a polymer.
Passive transport is a movement of ions and other
atomic or molecular substances across cell
membranes without need of energy input. Unlike
passive transport
active transport, it does not require an input of
cellular energy because it is instead driven by the
tendency of the system to grow in entropy.
active transport is the movement of molecules across
a membrane from a region of lower concentration to
active transport a region of higher concentration—against the
concentration gradient. Active transport requires
cellular energy to achieve this movement.
