English Grammar
1. Identify the predicate in the following sentence: "The children built a sandcastle on the beach."
- A. on the beach
- B. built a sandcastle
- C. children
- D. the
Correct answer: B
Rationale: The predicate is the verb and any words following it that describe the action or state of being of the subject.
2. Which digestive enzyme is primarily responsible for breaking down proteins?
- A. Pepsin
- B. Lipase
- C. Amylase
- D. Maltase
Correct answer: A
Rationale: The correct answer is A: Pepsin. Pepsin is primarily responsible for breaking down proteins in the stomach. It is an enzyme produced by the gastric chief cells in the stomach lining and works in a highly acidic environment to break down proteins into smaller peptide fragments. Lipase, on the other hand, is responsible for breaking down fats, amylase for breaking down carbohydrates, and maltase for breaking down maltose (a type of sugar). Therefore, pepsin is the correct enzyme involved in the digestion of proteins.
3. Which property of a substance refers to the force exerted on an object due to gravity?
- A. Mass
- B. Weight
- C. Density
- D. Volume
Correct answer:
Rationale: Weight is the measure of the force exerted on an object due to gravity. It is calculated as mass multiplied by the acceleration due to gravity.
4. When referring to blood vessel walls, the term "atherosclerosis" describes:
- A. The normal process of blood vessel wall thickening with age.
- B. The inflammation of the inner lining of blood vessels.
- C. The dilation and weakening of a blood vessel wall (aneurysm).
- D. The abnormal buildup of plaque within the arterial walls.
Correct answer: D
Rationale: Atherosclerosis is a condition characterized by the abnormal buildup of plaque within the arterial walls. This plaque is made up of substances like cholesterol, calcium, and fatty compounds. Over time, this plaque can harden and narrow the arteries, leading to reduced blood flow and potential complications like heart attacks and strokes. Options A, B, and C do not accurately describe atherosclerosis. Option A is incorrect because atherosclerosis is not a normal aging process but rather a disease. Option B is incorrect because atherosclerosis involves the buildup of plaque rather than inflammation of the inner lining of blood vessels. Option C is incorrect because an aneurysm is a different condition involving the dilation and weakening of a blood vessel wall, not the buildup of plaque seen in atherosclerosis.
5. Which type of energy is associated with the random motion of particles in a substance?
- A. Potential energy
- B. Mechanical energy
- C. Thermal energy
- D. Chemical energy
Correct answer: c
Rationale: Thermal energy is related to the random motion of particles in a substance and is associated with temperature.
6. Which vitamin is essential for calcium absorption and bone health?
- A. Vitamin A
- B. Vitamin C
- C. Vitamin D
- D. Vitamin E
Correct answer: C
Rationale: The correct answer is Vitamin D. Vitamin D plays a crucial role in calcium absorption in the intestines, which is essential for maintaining strong and healthy bones. It helps regulate calcium and phosphorus levels in the body, promoting bone mineralization and growth. Vitamin A is important for vision and immune function, not specifically for bone health. Vitamin C is essential for collagen synthesis but not directly involved in calcium absorption. Vitamin E is an antioxidant that protects cells from damage but does not have a direct role in bone health. Therefore, Vitamin D is the correct choice for supporting calcium absorption and bone health.
