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.

They should cultivate the world’s most significant old growth trees prior they are gone, Replant trees the Earth with the children of these trees to furnish the numerous of beneficial environment services which is essential to all life forms to succeed including outsourcing of oxygen, impounding carbon dioxide, providing beneficial vaporizers and medicines; basically a global warming result, and to document the genetics of ancient kinds of trees inside libraries around the globe for the near future.</span>

answer : space probe ( option 1 )
Explanation:
The unpiloted spacecraft designed to gather information while orbiting planets is Space probe
Space probe is a spacecraft that practically gathers ( scientific ) data from the planets which it sends back to scientists on earth for study. A space probe is unlike other spacecrafts because they do not require the presence of an astronaut.
