As the zygote goes through mitosis and creates more cells. Each cell is called a stem cell. In order to become a certain type of
cell, these cells will become Or This means they will turn Genes for the type of cell they are becoming, and turn Genes for the type of cell they won't be.
As the zygote goes through mitosis and creates more cells. Each cell is called a stem cell. In order to become a certain type of cell, these cells will become <u>differentiated </u>Or This means they will turn Genes <u>on </u>for the type of cell they are becoming, and turn Genes <u>off</u> for the type of cell they won't be.
Stem cells become specialized cells through the process of differentiation. The stem cells all have identical DNA in them. They become specialized for a particular function (s) through the process of differentiation. During this process, some <u>specific genes are either turned on or off</u>. <em>Cells in which the same genes are expressed become specialized for similar functions and can then come together to form a tissue.</em>
Absorption is the transformation of radiant power to another type of energy, usually heat, by interaction with matter. The transmittance t of a medium is defined by the ratio of transmitted radiant power to incident radiant power.
