Answer:
DISADVANTAGES
Embryonic stem cells can have high rejection rates
Adult stem cells have a determined cell type
Obtaining any form of stem cell is a difficult process
Stem cell treatments are an unproven commodity
Stem cell research is a costly process.
ADVANTAGES
can help enhance the growth of new healthy skin tissue, enhance collagen production, stimulate hair development after incisions or loss, and help substitute scar tissue with newly developed healthy tissue.
This answer would be all of the above
The cell membrane maintains homoeostasis in the body which is the process by which cell maintains a fairly constant environment.
<h3>What is the cell membrane?</h3>
The cell membrane is a lipid bilayer membrane which separates the contents of a cell from the external environment.
The correct graphical chart is as follows:
- cell membrane maintains homeostasis
- active transport requires energy
- passive transport does not require energy
- Diffusion occurs either through osmosis or facilitated diffusion
- facilitated diffusion occurs through protein channels
- Osmosis involves movement of water
- Endocytosis is the process the cell takes in substances into its inner compartment
- Exocytosis is the process the cell takes in substances into its inner compartment
- Pinocytosis is cell drinking
- Phagocytosis is cell eating
Therefore, the process by which cell maintains a fairly constant environment is called homoeostasis and is maintained by the cell membrane.

D - Allow pH to change drastically.
The reason that we have buffer in our system is to protect AGAINST sudden change of pH
