What is the mineral necessary for chemical clotting?
- A. Iron
- B. Potassium
- C. Sodium
- D. Calcium
Correct Answer: D
Rationale: Calcium is the mineral necessary for chemical clotting. When there is a cut or injury that causes bleeding, the body's clotting process is initiated to stop the bleeding. Calcium ions play a crucial role in several steps of the clotting cascade, helping to activate various clotting factors and promoting the formation of a stable blood clot. Without sufficient calcium, the blood would not be able to clot properly, leading to potential complications with excessive bleeding.

- A. Chordee
- B. Phimosis
- C. Epispadias
- D. Hypospadias
Correct Answer: B
Rationale: Phimosis is the term used to describe the narrowing of the preputial opening of the foreskin in males.
