Telomerase is an enzyme that is produced only in cells that are actively dividing. For this reason it is generally absent from b

ody tissues in adults. Bone marrow is an exception to this rule, however, since even in adults, bone marrow cells continually divide to replace old blood cells. Cancers are another exception, because their cells are rapidly dividing.
The information provided most strongly supports which of the following?
(A) Telomerase is the only enzyme that is present in cancerous cells but absent from cells that are not actively dividing.
(B) In children, the only body tissues from which telomerase is absent are those in which cells are not rapidly dividing.
(C) The presence of telomerase in bone marrow is no indication of bone marrow cancer.
(D) Cancer of the bone marrow develops more rapidly than cancer growing in any other kind of adult tissue.
(E) The level of telomerase production is always higher in cancerous tissue than in noncancerous tissue.

Answer:

Option (D).

Explanation:

Telomerase enzyme is necessary for the replication of telomeres. This enzymes are also known as terminal transferase and made of ribonucleoprotein.

The increased telomerase activity is the common characteristics of the cancer cell that distinguish them from the normal cells. The cancer cells divide continuously and require the telomerase activity for the end replication of the DNA.

Thus, the correct answer is option (D).

________is when the kidneys produce too much hydrogen or retain too much hydrogen which leads to an increase in carbonic acid pr
Setler [38]

Metabolic acidosis is when the kidneys produce too much hydrogen or retain too much hydrogen which leads to an increase in carbonic acid production. Or the kidneys excrete too much base.

<h3>What is metabolic acidosis?</h3>
  • The primary function of the kidney is to purge toxins from the blood and convert waste products into urine.
  • Around 160 grams of weight and one to one and a half litres of urine are excreted daily by each kidney.
  • When the kidneys do not properly eliminate acids from the blood into the urine, renal tubular acidosis (RTA) ensues.
  • The result is an excessively high blood acid level, or acidosis.
  • While having some blood acid is natural, having too much acid can cause numerous biological functions to become unbalanced.
  • When there is too much acid in the body's fluids, it is called acidosis.
  • When your kidneys and lungs are unable to maintain a healthy pH level in your body, acidosis results.
  • Acid is created by numerous bodily activities.

Explain why the growing of willow for biofuel is an example of sustainable development.
Anuta_ua [19.1K]
Growing willow for biofuel is sustainable development because it is a source of fuel which potentially will never run out. For every willow tree that is cut down, another can be planted in its place. This means that the source of fuel is potentially limitless and subsequently sustainable.

Function of a mitochondion
olya-2409 [2.1K]

Answer:

mitochondria are to produce the energy currency of the cell, through respiration, and to regulate cellular metabolism.

Explanation:

the role of mitochondrion is to generate the energy commodity of the cell, by respiration, and control of cell metabolism.Mitochondrial is the ATP synthesis site for the cell. The amount of mitochondria present in a cell is also a strong predictor of the cell 's rate of metabolic activity; cells that are very metabolically active, such as hepatocytes, may have more mitochondria.

hope this helped!
