PLEASE HELLPPp Stem cells can become any type of cell in the human body, making them ideal for many types of therapies. One area of possible use is in brain cell transplants that could help people with spinal cord injuries and neurodegenerative diseases such as Parkinson’s disease. Even though there is great potential for helping people, what is one ethical issue that could arise from the use of stem cells?

A. The source of the stem cells
B. The cost of obtaining the stem cells
C. The method of storing the stem cells
D. The procedure for transplanting the stem cells

D

Explanation:

Stem cells transplanted into the facial tissue of two people with Parkinson’s disease led to sustained reductions in motor and non-motor symptoms, lower medication doses, and a better quality of life, a case study reported.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
