Researchers prefer to use embryonic stem cells instead of adult stem cells because embryonic stem cell can differentiate into more type of cells.Human embryonic stem (ES) cells capture the imagination because they are immortal and have an almost unlimited developmental potential. Embryonic stem cells are pluripotent cells not unipotent. After many months of growth in culture dishes, these remarkable cells maintain the ability to form cells ranging from muscle to nerve to blood—potentially any cell type that makes up the body.
Answer: OSMOSIS
Explanation:
OSMOSIS is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. It's very useful in biological systems and is dependent on the following factors:
- osmotic pressure and
- osmotic gradient.
Osmotic pressure: this is defined as the least pressure that needs to be applied in a solution to discontinue the transfer of solvent across a semipermeable membrane.
Osmotic gradient: this compares the concentration of solutions divided by a semipermeable membrane. The concentration of a specific particle dissolved in a solution is known through osmotic gradient.
Answer:
Explanation:3Natural selection is dependent upon the environment; different environments produce different adaptations in species
Answer:
The cell needs food in order to get energy.

Hope this helps!
If not, I am sorry.
It will have to go through the star cycle.
