Answer:
Cell Division
Explanation:
Cells reproduce by the process of CELL DIVISION, which is the formation of an increased number of cells from a single parent cell. Mitosis is the type of cell division used for the multiplication of cells as it involves the synthesis of two identical number of daughter cells from a single parent cell.
However, certain drugs that may prevent the unregulated reproduction of cells is trying to directly affect the process of cellular division in that cell. This is because cell division is the way through which cells reproduce themselves.

Greenhouse gases(also known as GHGs) are gases in the earth's atmosphere that trap heat, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals.
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and some is absorbed and re-radiated by greenhouse gases.
