Explanation:
Answer: both parathyroid hormone and calcitrol.
Explanation:
In the body calcium homeostasis, which is generally defined as the maintenance of specific internal conditions, is mediated by the endocrine system through hormonal control; hormones are usually specialized signal molecules derived from lipids or amino acids. This regulates the calcium flux between the bloodstream and the bone; and the hormones responsible, change the ratio of osteoclast activity to osteoblast activity -osteoblasts build bone while osteoclasts breakdown or degrade bone.
Hormones responsible include calcitonin (from special parafollicular cells in the thyroid gland), cacitrol (activated vitamin D) and the parathyroid hormone (from the parathyroid glands). These affect the absorption of calcium from the gut, or kidney reabsorption; both parathyroid hormone and calcitrol act by causing the release of calcium ions into the bloodstream as the bone is degraded by osteoclasts.
Answer:
One.
Explanation:
The attached figure shows the diagram of the given question.
We need to find how many angles are alternate exterior angles with angle 5?
Exterior angle = Angle that is made outside of the shape
Alternate angle = an angle opposite of a transversal line of another angle.
From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.
Answer:
The net movement of water (osmosis) is in the direction of increased solute concentrations. An easy way to visualize this rule is simply that the net water movement is from an area of high water concentration (little dissolved solute) to an area of low water concentration (high levels of solute).
Explanation:
Answer:
In case of sunstroke the body is unable to sweat because the body is dehydrated.
The temperature of the body won't increase further because there can be no more evaporation in body as it cannot sweat more from the skin surface.
The skin dissipates the heat and cools the body preventing the overheating of the body.
The skin appears to be red in color because the blood is dilated and dissipiated into the whole body for cooling.
