Bones are a dense type of connective tissue that is impregnated with which of the following?

• A. Proteins
• B. Salts
• C. Carbohydrates
• D. Fats

Answer: (B)

Bones are primarily impregnated with salts, specifically mineral salts such as calcium phosphate and calcium carbonate. This mineralization process contributes significantly to the hardness and strength of bone tissue. The presence of these salts allows bones to perform their role in providing support and structure to the body, as well as housing for bone marrow, which is vital for blood cell production. In contrast, while proteins are important components of bone matrix, they do not define the mineralization of bone to the same extent. Carbohydrates do not play a direct role in bone structure; they mainly serve as energy sources and are involved in other biological processes. Fats are present in bone marrow but are not integral to the structural properties of the bone itself. Thus, the impregnation of bones with mineral salts is what primarily gives them their unique rigidity and strength.
