While exercise is important for stimulating muscle growth, it is during the rest period that the actual growth and repair occur.

What part of the body is composed of the highest percentage of water?
Correct Answer
C. The Lungs

To perform these functions efficiently, the lungs need to be moist, and water helps in maintaining this moisture. Additionally, water is essential for the proper functioning of the respiratory system and helps to keep the airways clear and lubricated. Therefore, the lungs contain a significant amount of water, making them the correct answer.

What is dietary fiber?
Correct Answer
C. Indigestible Plant Parts
Explanation
Dietary fiber refers to the indigestible parts of plant foods that cannot be broken down by the human digestive system. These plant parts, such as the skin, seeds, and stalks, pass through the digestive tract largely intact, providing bulk and promoting healthy bowel movements. They are not broken down or absorbed in the small intestine, but instead, reach the large intestine where they are fermented by beneficial gut bacteria. This process helps to maintain a healthy gut environment, regulate blood sugar levels, lower cholesterol, and promote feelings of fullness.
