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.
