The kidneys is controlled by hormones and by the composition of the urine since the hormone released is called ADH which is produced by the pituitary gland.
Answer:
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.
Answer:
the base sequence would be GAA UAG GUA
Explanation:
Compared to DNA, RNA uses uracil instead of thymine, therefore every T changes to U.
Answer:
The answer is A) You would find 46 chromosomes in a Haploid cell and B.) You would find 23 chromosomes in a Diploid cell.
Explanation:
A human haploid cell, such as a skin cell, is a complete unit. It is capable of duplicating itself and the new cell has exactly the same number of chromosomes, which is 46.
A human diploid cell, such as a human egg cell, has half the number of chromosomes, which is 23.
Hope this helps!! Have an Awesome day!!! :-)
Answer:
Calcium
Explanation:
Parathyroid hormone (PTH) is a hormone that is secreted by the parathyroid gland. It is the major regulator of the plasma concentration of calcium ions. It regulates calcium ions in the kidney, intestine and bones.
In the kidney, is involved in the re-absorption of calcium in distal ducts and the renal collecting duct, it is also involved in activating the conversion of 25-hydroxy vitamin D into 1,25-dihydroxy vitamin D (calcitriol).
In the intestine, PTH is involved in the absorption of calcium, by increasing vitamin D production.
In the bone, it helps in regulating calcium levels; when serum calcium level is low, PTH stimulates the activity of the osteoclast, to produce more calcium.
