A) To increase body weight
B) To enhance joint flexibility
C) To improve body aesthetics
D) To provide varying functions and protection

Answer 1

Having different thicknesses of muscle groups provides varying functions and protection. The benefit of having multiple layers of muscles is to enhance joint flexibility, speed, and agility.

Step-by-step explanation:

The different thicknesses of muscle groups provide varying functions and protection for the body. One benefit of having multiple layers of muscles is to enhance joint flexibility. Muscles attached close to joints allow for speed in movement because small muscle contractions can produce large movements of limbs in a short period of time. In addition, having muscles close to joints enables flexibility and agility, as the large numbers of joints and the ranges over which they function allow for a broad range of movement.
