the skeletal system serves all of the following functions except:
a. bone marrow produces red and white blood cells which help carry oxygen through the blood and fight diseases.
b. the skeleton gives the human body its support, shape, and form.
c. the skeletal system helps to protect vital organs.
d. the skeletal system aids in the production of hormones that signal muscle and hair growth.

please select the best answer from the choices provided.
○ a
○ b
○ c
○ d

Explanation:

• Option A: Bone marrow (part of skeletal system) produces blood cells, which is a function of the skeletal system.
• Option B: The skeleton provides support, shape, and form to the body, a key function of the skeletal system.
• Option C: The skeletal system protects vital organs (e.g., ribcage protects heart and lungs), a known function.
• Option D: The skeletal system does not aid in producing hormones for muscle and hair growth. Hormone production for such functions is typically related to endocrine glands (e.g., pituitary, thyroid, etc.), not the skeletal system.

Answer:

D. The skeletal system aids in the production of hormones that signal muscle and hair growth.
