1. Which type of muscle is characterized by voluntary control and is responsible for body movement?

• A. Cardiac muscle
• B. Smooth muscle
• C. Skeletal muscle
• D. Connective tissue

Correct answer: c

Rationale: The correct answer is C: Skeletal muscle. Skeletal muscles are characterized by voluntary control, meaning they are under conscious control, allowing us to move our body parts as desired. These muscles are attached to bones and are responsible for movements such as walking, running, and lifting objects. Cardiac muscle (A) is found in the heart and is involuntary, while smooth muscle (B) is found in internal organs and is also involuntary. Connective tissue (D) provides support and structure to the body but is not responsible for body movements.

2. Which vitamin deficiency can lead to kidney stones?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin D
• D. Vitamin K

Correct answer: D

Rationale: The correct answer is D, Vitamin K. Vitamin K plays a role in blood clotting and bone health. A deficiency in Vitamin K can lead to an increased risk of kidney stones due to the improper regulation of calcium in the body. Calcium can accumulate in the kidneys and form stones if not properly managed. Vitamin K deficiency can disrupt the balance of calcium in the body, contributing to the development of kidney stones. Therefore, it is important to ensure an adequate intake of Vitamin K to prevent kidney stone formation.
