Buprenorphine is a partial opioid agonist, which causes it to be less addictive than either heroin or methadone. The âhighâ produced by buprenorphine is less intense, and the side effects are less dangerous.

I. Cell Division . Life is based on the ability of cells to reproduce, or make copies of themselves. This is done by a process called cell division = one cell divides into two cells.

For multicellular organisms (like us) cell division allows an organism to grow and develop from a single cell to trillions of cells, and also to repair and replace cells.
