Answer: Option A) Parathyroid glands
Explanation:
The Parathyroid gland located in the neck region helps in the secretion of an hormone called Parathormone.
This hormone helps to raise the levels of calcium ions in the body, by preventing the loss of calcium ions through urine, and also preventing excess deposit of calcium ions in the bone, thus regulating bone density.
Cell division starts with one parent cell and finishes with two cells. Each daughter cell has the same DNA as the parent cell
As light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply. As the rate increases, eventually another factor will come into short supply.
The answer to this question would be: insulin
Insulin is a hormone that produced by the pancreas. Insulin makes sugar go inside cells. Sugar is the food for cells. Without insulin, the sugar can't enter the cell and the cell food is depleted. This will cause the body feel that the sugar is not enough and trying to increase the sugar concentration. This will result in the increases of blood sugar level.
