Answer:
DNA Polymerase
Explanation:
In E. coli, the DNA polymerase that handles most of the synthesis is DNA polymerase III. There are two molecules of DNA polymerase III at a replication fork, each of them hard at work on one of the two new DNA strands.
Explanation:
When calcium levels in the blood become too low, parathyroid hormone leads to an increase in calcium by degrading bone. In response, calcitonin from the thyroid is released when the levels are high again, to decrease calcium levels in the blood.
Further Explanation:
During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.
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. 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), calcitriol (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 calcitriol act by causing the increase of calcium ions into the bloodstream as the bone is degraded by osteoclasts.

I'm pretty sure that it's C- Water is a good solvent. hope this helps.
Answer:
I believe the correct answer from the choices listed above is option A. The possible explanation of the statement above would be because the groundwater has been exhausted. Because of such the pressure beneath needs to be in equilibrium with the one above causing the ground to sink.
I hope u get what ur looking for and I wish u give me brainlist But I know u won't cuz everyone say that . But thank you so much if u put for me and It would be a very appreciated from you and again thank you so much
Sincerely Caitlin,
! Thank youuuu
