How do the functions of the skeletal and muscular system differ? A.
Muscles send signals to the body, and bones are responsible for movement.
B.
Bones provide structure and support to the body, while muscles move the bones.
C.
Bones send signals to the body, and muscles are responsible for movement.
D.
Muscles provide structure and support to the body, while bones move the muscles.

The functions of the skeletal and muscular systems differ in that bones provide structure and support to the body, while muscles move the bones.

Explanation:

The skeletal and muscular systems have complementary functions, which is why they are sometimes referred to as the musculoskeletal system.

Bones are solid organs, made up of calcium, which are connected to each other through joints, which provide them with a certain range of mobility. The main functions of the bones are protection and body support.

Muscles are contractile organs that are attached to bones by tendons. The location and relationship of the muscle to the bones is what makes it possible for the bony skeleton to move. Muscle contraction and relaxation is what contributes to the different body movements.

The other options are not correct because:

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
