Explanation:

Question 14

The back has many intervertebral (or "gliding", "cartilaginous" etc., but most commonly "intervertebral") joints, but the standard fill - in here is "intervertebral" (or for a more general term, "cartilaginous" or "synovial" but intervertebral is specific to back). However, the most common answer for "Your back is full of ____ joints" is "intervertebral" (or sometimes "cartilaginous" but intervertebral is more precise).

Calcium (found in milk, as the pre - written "Milk" suggests, since milk is rich in calcium) helps to make bones hard. Calcium is a key mineral for bone mineralization.

Muscles make up to about 40 - 50% of body weight (average is around 40% for men and 30 - 40% for women, but the general range taught in basic biology is up to 50% or around 40%). The most common answer here is 40 - 50, with 40 or 50 being common. A typical answer is 40 (or 50, but 40 is a common value taught).

Answer:

intervertebral (or cartilaginous/synovial - intervertebral is most accurate for back)
