Explanation:

• Question 7: Melanin is the pigment that determines skin color. Keratin is a protein in skin, hair and nails, mucus is a secretion, and tyrosine is an amino - acid involved in melanin production but not the determinant of skin color.
• Question 8: Osteocytes are bone cells. Striated and smooth muscles are types of muscle tissue, and blood is a connective tissue not containing osteocytes.
• Question 9: Cartilage lacks a direct blood supply, which leads to slow healing. Bone, muscle, and adipose tissues have blood supplies.

Answer:

Question 7: C. melanin
Question 8: C. bone
Question 9: D. cartilage
