THE work is to research medical uses of stem cells. Where are stem cells found? How are they collected? And what are they used for? I’m looking for as much detail as possible. thanks

Explanation:

The largest concentration of blood stem cells is in your bone marrow. The bone marrow is the tissue inside the some of your bones. This is usually located in your hip and thigh bones. Stem cells can be usually becollected exactly from the bone marrow spaces, most often from the pelvic bones. Several puncture sites are made along the bone and the cells are removed using a needle. This procedure is known as a bone marrow harvest. In stem cell transplants, stem cells removed damaged cells damaged by chemotherapy or disease or serve as a way for the donor's immune system to fight some types of cancer and blood-related diseases, such as leukemia, lymphoma, neuroblastoma and multiple myeloma. These transplants use adult stem cells or umbilical cord blood.

Hope this helps!

Stem cell are an undifferentiated cell that can divide itself to produce some offspring cells that continue as stem cells. Some cells that are destined to differentiate (become specialized). Stem cells are also an ongoing source of the different cells that make up tissues and organs of animals and nature life aka plants. Stem cells are a great interest being because they have potential development in healing or replacing damage cells such as Parkinson disease, heart disease, and diabetes. There are only two types of stem cells thought, adult stem cells and embryonic stem cells. But Stem cells are pretty ubiquitous in the body appearing in many different places including the brain, blood, bone marrow, muscle, skin, heart, and liver tissues.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

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.
