1. Which type of immunity is demonstrated by the transfer of a mother's immunoglobulin across the placenta to protect the child?
- A. Natural active immunity
- B. Natural passive immunity
- C. Artificial active immunity
- D. Artificial passive immunity
Correct answer: B
Rationale: The immunoglobulin passed from the mother to the child through the placenta is an example of natural passive immunity, making choice B the correct answer. This transfer gives the child temporary immunity to various diseases without their immune system having to work. On the other hand, natural active immunity (Choice A) occurs when the body produces its own antibodies in response to an antigen. Artificial active immunity (Choice C) is achieved through vaccinations, where the immune system is stimulated to produce antibodies against a specific disease. Artificial passive immunity (Choice D) is a temporary immunity that involves the transfer of pre-formed antibodies from another source.

- A. Vitamin B1
- B. Vitamin B2
- C. Vitamin B3
- D. Vitamin B12
Correct answer: A
Rationale: Thiamin, or Vitamin B1, plays a crucial role in energy metabolism and the proper functioning of the nervous system.

- A. R.A 9173
- B. LOI 949

4. What is the first step in the scientific method?
- A. Conduct an experiment
- B. Make an observation and ask a question
- C. Formulate a hypothesis
- D. Reach a consensus
Correct answer: B
Rationale: The first step in the scientific method is to make an observation and ask a question. This is because the scientific method is a systematic process of investigation that begins with observing a phenomenon or asking a question about it. This is followed by formulating a hypothesis (Choice C), designing and conducting an experiment to test the hypothesis (Choice A), and analyzing the results to reach a consensus or conclusion (Choice D). Therefore, choices A, C, and D are incorrect as they represent steps that occur after the initial observation and question.
5. What is the primary function of antioxidants in the diet?
- A. Provide energy
- B. Support muscle growth
- C. Neutralize free radicals
- D. Increase blood sugar
Correct answer: C
Rationale: The primary function of antioxidants in the diet is to neutralize free radicals. Free radicals can cause cellular damage, leading to various chronic diseases. Antioxidants help combat this oxidative stress by neutralizing free radicals. Choices A, B, and D are incorrect because antioxidants do not provide energy, support muscle growth, or increase blood sugar; their main role is in combating oxidative stress.
