Final answer:
Simultaneous absorption of Ca and PO4 in soft tissue leads to the formation of calcium phosphate, a mineral composed of hydroxyapatite. This is known as calcification and occurs in the presence of collagen fibers.
Step-by-step explanation:
The simultaneous absorption of calcium (Ca) and phosphate (PO4) in soft tissue can lead to the formation of calcium phosphate.
Calcium phosphate is a mineral salt primarily composed of hydroxyapatite, which is formed from the combination of calcium and phosphate ions. This process is known as calcification and occurs in the presence of collagen fibers.
