Answer:
The correct answer will be option-D
Explanation:
Stem cells are the cells which have the ability to form different types of cells. They differentiate and specializes to perform different functions in the body and thus forms the different cells.
The differentiation and specialization are controlled at the gene level by different patterns of gene expression. The pattern of gene expression is not fully understood during development but research have shown that the gene expression is influenced by the different environmental signals and internal regulators.
Thus, option-D is the correct answer.
Answer: diffusion
Explanation:
Diffusion is the over all movement of molecules from one region where it is in high concentration to another another region where it is in lower concentration.
This movement continues until the concentration of both regions are equal. Smaller non polar molecules are able to diffuse through the lipid bilayer of the membrane .
Movement through the membrane is dependent on the concentration gradient, that is the difference in concentration between the two areas.
It is also dependent on the size of the molecule
