1. Which type of immunity does the MMR vaccine provide?

Correct answer: A

Rationale: The correct answer is A: Artificial/active. The MMR vaccine provides artificial/active immunity. It works by introducing a weakened or killed form of the virus to trigger the body's immune response, leading to the production of antibodies that offer long-lasting protection against measles, mumps, and rubella. Artificial immunity is obtained through medical intervention, such as vaccination, while active immunity involves the immune system's direct response to an antigen. Choices B, C, and D are incorrect because the MMR vaccine does not provide passive immunity nor is it acquired naturally; instead, it stimulates the body to actively produce its immune response.

2. Which of the following is a representation of a natural pattern or occurrence that is difficult or impossible to experience directly?

Correct answer: B

Rationale: A model is a representation used by scientists to understand and explain natural phenomena that are challenging or impossible to observe directly. Models help visualize complex systems or processes that are not easily accessible for direct observation. The other choices are incorrect because: A) A theory is an explanation or interpretation of observable facts or phenomena. C) A law describes a consistent and universal phenomenon or relationship in nature based on repeated observations. D) An observation is a direct act of watching or taking note of a phenomenon or behavior.

3. Which of the following is a function of the liver?

Correct answer: B

Rationale: The correct function of the liver is to store bile. Bile is produced in the liver and stored in the gallbladder until it is needed to aid in the digestion of fats. While the liver does produce bile, its primary role is to store and release it. Choices A, C, and D are incorrect. Producing digestive enzymes is mainly the function of the pancreas, filtering waste products from the blood is primarily done by the kidneys, and transporting nutrients to cells is typically associated with the circulatory system rather than the liver.

4. Which of the following organs is responsible for filtering waste from the blood?

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys play a vital role in filtering waste from the blood, regulating fluid and electrolyte balance in the body. The liver is involved in detoxification and metabolism, while the pancreas aids in digestion and blood sugar regulation. The heart is responsible for pumping blood throughout the body and does not directly filter waste from the blood.

5. Which of the following is part of the cardiovascular system?

Correct answer: A

Rationale: Blood vessels are indeed part of the cardiovascular system. They are crucial components that facilitate blood circulation by carrying blood throughout the body. The cardiovascular system consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. Blood vessels play a vital role in delivering oxygen and nutrients to tissues and removing waste products. The brain, kidneys, and lungs are not part of the cardiovascular system; instead, they belong to other body systems. The brain is part of the nervous system, kidneys are part of the urinary system, and lungs are part of the respiratory system. Therefore, the correct answer is blood vessels (Choice A). Choices B, C, and D are incorrect as they are not components of the cardiovascular system but belong to different body systems.
