Therefore, option d) Mental agility is not a component of physical fitness.
37. Which of the following is the most effective way to prevent dehydration during exercise?
a) Drinking sugary drinks
b) Drinking alcohol
c) Drinking water
d) Not drinking anything
Answer: c) Drinking water
Explanation: Dehydration occurs when the body loses more fluids than it takes in, leading to a decrease in blood volume and a rise in body temperature. During exercise, it is essential to drink plenty of water to prevent dehydration. Sugary drinks and alcohol can actually worsen dehydration and should be avoided. Therefore, option c) Drinking water is the correct answer.
38. Which of the following is a symptom of a heart attack?
a) Sudden chest pain or discomfort

44. Which of the following is an example of a competitive inhibitor?
Answer: B) Ibuprofen
Explanation: A competitive inhibitor is a compound that binds to the active site of an enzyme and prevents the binding of the substrate. Ibuprofen is an example of a competitive inhibitor because it competes with arachidonic acid for binding to the active site of the cyclooxygenase enzyme, which is responsible for the synthesis of prostaglandins that mediate pain and inflammation.
45. Which of the following is NOT a function of the skeletal system?
A) Protection of vital organs
B) Production of blood cells
C) Storage of minerals
D) Regulation of body temperature
