Bone consists of how much inorganic and organic matter?

1/2 inorganic and 1/2 organic
2/3 inorganic and 1/3 organic
3/4 inorganic and 1/4 organic
1/3 inorganic and 2/3 organic

The correct answer is: 2/3 inorganic and 1/3 organic

Bone consists of approximately 2/3 inorganic matter and 1/3 organic matter. This is due to the fact that bone is primarily made up of minerals, such as calcium and phosphorus, which make up the inorganic component. The organic component includes collagen and other proteins that provide strength and flexibility to the bone structure. Option A is incorrect because it assumes an equal distribution of inorganic and organic matter, which is not the case. Option C is also incorrect because it overestimates the amount of inorganic matter. Option D is incorrect because it underestimates the amount of inorganic matter. Therefore, B is the correct answer as it represents a more accurate proportion of inorganic and organic matter in bone.
