Explanation:
Telomerase is an enzyme that is produced in the body. It prevents the shortening of the length of telomeres.
Telomerase is not usually activated in the cells of the body but you can find them in cells responsible for the production of sperm and egg in humans.
In others for cells to keep living , the length of the telomere must be maintained and this is one of the reasons why cancer cells thrives in the body and keeps dividing and spreading because telomeres are always present in cells that keep dividing.
Telomere are very essential to growth of cancerous cells. Shortening the length of telomeres is not enough to kill cancerous cells as we have cancer cells with short length ( bone, kidney, prostate cancer). We have to combine other methods of cancer treatment to be able to eradicate the cancerous cells from the body.
Bone marrow is a body tissue where the cells are always dividing because this is crucial and essential for the replacement of old cells. In the bone marrow we can find enzyme telomerase present hence, this makes the bone marrow an exception.
<span>Dora has been admitted to veterinary school and is excited to begin. She has an intense fear of dogs, probably stemming from when she was bitten by a dog many years ago. Dora knows that she must overcome this fear before she begins vet school. She finds a therapist who has her stand in a room with five dogs; the therapist remains in the room with her. After a few minutes of thinking that she would need to run out or start screaming, she realized that the dogs were actually not hurting her. After about an hour and a half, she noticed her anxiety level was substantially lower than it was before she entered the room. The technique seemed to be working. Dora's therapist was using the "COUNTERCONDiTIONING" technique known as "Stimulus Substitution".</span>
