Answer:
receptor binding
Explanation:
Hormones are able to act specifically on target cells through receptor binding. This process enables target cells to react to a specific hormone only. The cells have hormone receptors within or on their surface which permits the specific hormone to act on it, thereby initiating a series of functions of the particular cell that has the hormone receptor. For example, thyroid receptors respond to thyroid-stimulating hormone.
Answer:
Calcium and phosphate.
Explanation:
Mineralization may be defined as the process by which the inorganic substances can be precipitated by the organic matrix. Different types of mineralization are biomineralization and organicmineralization.
Mineralization process is important for the formation of shells, boned and teeth. The blood plasma consists of the phosphate, calcium and many inorganic ions. The calcium and phosphate is extracted from the blood plasma and deposit in the bone for the process of bone mineralization.
Thus, the answer is calcium and phosphate.
