The liver is responsible for regulating nutrient in the blood after absorption. Digested nutrient are absorbed into the bloodstream through capillaries in the villi that line the small intestine. Liver regulate nutrient in the blood example if body sugar levels increases the liver removed sugar from the blood.
The majority of the accessible drinking water on our planet comes from glaciers.
Germinal cells can most likely divide indefinitely due to the activity of an enzyme called Telomerase.
- The telomeric sequences are extra sequences which are reduced during several rounds of replication.
- However, these are restored by the enzyme telomerase which keeps the length of the telomere sequence enough to undergo several rounds of replication.
- Generation after generation, germ cells must precisely transmit genetic information.
- They have a lot of telomerase activity to stop the genetic material from being lost during meiosis. The parents' genetic material is kept intact thanks to the high level of telomerase.
- The primary region of the chromosome, which contains the genes necessary for life, would become shorter without telomeres with each cell division. Telomeres thereby permit cell division without gene loss.

<span> </span>A high metabolic
rate means that the cells in the tissue will needs a high rate of gas exchange
as the cells will be producing a high amount of CO2 during production of energy. The dense network of capillaries ensure that
the cells are adequately provided with oxygen.
