<span>An independent variable is variable that is not affected in the
experiment. It is what experimenter controls. On the other side, a dependent
variable is called dependent because it depends on the independent variables.
It is what is affected during the experiment.
In this case, the growth of pea plants depends on different types of
fertilizer. So, the growth of pea plants is the dependent variable and different
type of fertilizer is the independent variable.</span>

Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.
Genetic mutations can occur during the life of a cell due to outside factors such as:
- The <u>food </u>we eat
- The <u>environment </u>we expose the cell to
- The <u>substances </u>that touch the cell (e.g skin cells)
That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of <u>programmed cell death</u>.
<u>Programmed cell death </u>is what tells a cell when it should stop growing and dividing. This is a <u>regulatory function </u>designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The <u>accumulation </u>of these cells is referred to as cancer.
