1. Which of the following is true about calcium-rich foods? I. Canned salmon with bones contains calcium. II. Cheese is a lactose-free food. III. Condensed soup made with water is a calcium-rich food.
- A. I only
- B. I and II only
- C. II and III only
- D. III only
Correct answer: A
Rationale: The correct answer is 'I only.' Canned salmon with bones contains calcium as the bones are a good source of calcium, making statement I true. However, statement II is false as cheese is not a lactose-free food. Statement III is also incorrect as condensed soup made with water is not necessarily a calcium-rich food. Other calcium-rich options include dairy products like milk, yogurt, and specific non-dairy products like calcium-fortified juices, canned fish with bones, soybeans, and leafy greens.
2. Which statement is true about the pH of a solution?
- A. A solution cannot have a pH less than 0.
- B. A solution always has a pH of 7.
- C. A solution's pH is not influenced by its chemical composition.
- D. A solution with a pH of 14 is considered acidic.
Correct answer: A
Rationale: The pH scale ranges from 0 to 14, with 0 being the most acidic, 7 neutral, and 14 the most basic. A solution with a pH less than 0 would be outside the defined pH range, as 0 is the lower limit. Therefore, a solution cannot have a pH less than 0. Choice B is incorrect because a pH of 7 is considered neutral, not always the pH of a solution. Choice C is incorrect because a solution's pH is influenced by its chemical composition. Choice D is incorrect as a solution with a pH of 14 is considered highly basic, not acidic.
3. What are the components of the male external genitalia and their functions?
- A. Prostate gland: produces seminal fluid
- B. Scrotum: protects and maintains the temperature of the testes
- C. Penis: delivers sperm to female reproductive tract
- D. Urethra: conducts urine out of the body
Correct answer: C
Rationale: The correct answer is C. The penis is responsible for delivering sperm to the female reproductive tract during sexual intercourse. The scrotum is not involved in producing sperm but rather protects and regulates the temperature of the testes, which is essential for sperm production. The prostate gland is involved in producing seminal fluid, not sperm. The urethra serves the purpose of conducting urine out of the body and also acts as a passage for semen during ejaculation.
4. What is the primary function of the kidneys?
- A. To digest food
- B. To filter blood and produce urine
- C. To absorb nutrients
- D. To transport oxygen
Correct answer: B
Rationale: The primary function of the kidneys is to filter blood and remove waste products from the body, producing urine in the process. This function helps in maintaining the body's internal environment stable, a process known as homeostasis. Option A, 'To digest food,' is incorrect as digestion primarily occurs in the gastrointestinal system, not in the kidneys. Option C, 'To absorb nutrients,' is also incorrect because nutrient absorption mainly takes place in the intestines. Option D, 'To transport oxygen,' is incorrect as the lungs and circulatory system are responsible for oxygen transport, not the kidneys.
5. What is insulin, where is it produced, and what is its function?
- A. Produced in the liver, regulates fat storage
- B. Produced in the pancreas, regulates blood sugar
- C. Produced in the stomach, aids in digestion
- D. Produced in the kidneys, controls hydration
Correct answer: B
Rationale: Insulin is a hormone produced in the pancreas. Its primary function is to regulate blood sugar levels by facilitating the uptake of glucose by cells for energy. The other choices are incorrect as insulin is not produced in the liver (Choice A), stomach (Choice C), or kidneys (Choice D), and its function is not related to fat storage, digestion, or hydration. Therefore, the correct answer is B.
