3. Which of the following is NOT a function of the skeletal system?

• A. Support and structure
• B. Production of red blood cells
• C. Storage of minerals like calcium
• D. Insulation of the body

Correct answer: A

Rationale: The correct answer is A. The skeletal system provides support and structure to the body, allowing for movement and protecting internal organs. The production of red blood cells occurs in the bone marrow, which is a function of the skeletal system. Additionally, the skeletal system stores minerals like calcium, which play a crucial role in bone health and overall bodily functions. Insulation of the body is not a primary function of the skeletal system but is rather a function of adipose tissue and the integumentary system. Therefore, option A is the correct answer as it does not align with the functions of the skeletal system.

Correct answer: C

Rationale: The gut microbiome plays a crucial role in breaking down complex carbohydrates that our bodies cannot digest on their own. These microorganisms help ferment fiber and other carbohydrates, producing short-chain fatty acids that provide energy and support gut health. Additionally, a healthy gut microbiome contributes to the synthesis of essential nutrients like vitamin K and some B vitamins. This process enhances nutrient absorption and overall health. While the other options are important functions related to the gut microbiome, the breakdown of complex carbohydrates is a key aspect that highlights the significance of maintaining a healthy gut microbiome.
