Vikentia [17]

Answer:

differentiated; on; off

Explanation:

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>

Why are producers important to energy transfer within an ecosystem?
slamgirl [31]
<span>Answer: There are only two real sources of energy on the earth. One comes from geothermal from the creation of the earth and the other comes from the sun. You can say wind and nuclear or water, but water's movement is related to the tectonic activity and shaping of the earth and its spin, wind comes from unequal heating of the earth by the sun and nuclear energy comes from isotopes that were formed by a star. So producers are able to harness one of those two energy sources, the sun. Trees and plants are so common because they are using free energy, they have discovered a way to get something for nothing essentially. Predators can use the nutrients they make to supply their own energy but in the end everything boils down to the producers ability to make energy from the sun.</span>
