1. Which of the following substances is a common base found in household products?

Correct answer: b

Rationale: Ammonia is a common base found in household products. The other choices are acids.

2. What is the term for a genetic disorder caused by a mutation on the X chromosome?

Correct answer: C

Rationale: Rationale: - Autosomal dominant disorders (Option A) are caused by a mutation in one copy of a gene on one of the non-sex chromosomes (autosomes). These disorders do not specifically involve the X chromosome. - Autosomal recessive disorders (Option B) are caused by mutations in both copies of a gene on the autosomes. They are not directly related to mutations on the X chromosome. - Sex-linked dominant disorders (Option D) are rare and typically result in more severe symptoms in males because they only need one copy of the mutated gene on the X chromosome to express the disorder. This is not the term for a genetic disorder caused by a mutation on the X chromosome. - Sex-linked recessive disorders (Option C) are genetic disorders caused by mutations on the X chromosome. These disorders are more commonly seen in males because they have only one X chromosome, making them more susceptible to X-linked mutations. Females have two

3. Which of the following is NOT a function of the muscular system?

Correct answer: D

Rationale: The correct answer is D: "Regulating blood sugar levels." The muscular system primarily functions in movement, maintaining posture, and generating heat. Muscles contract and relax to allow movement and help us stay upright. They also produce heat through muscle contractions to maintain body temperature. Regulating blood sugar levels is primarily controlled by the endocrine system, specifically the pancreas and hormones like insulin and glucagon. Therefore, this function is not directly related to the muscular system.

4. Which vitamin is crucial for calcium absorption and synthesized in the skin upon sun exposure?

Correct answer: C

Rationale: The correct answer is C: Vitamin D. Vitamin D is crucial for calcium absorption as it helps the body absorb calcium from the diet. When the skin is exposed to sunlight, it produces vitamin D. This is why sunlight is often referred to as the 'sunshine vitamin.' Vitamin A (choice A) is important for vision and immune function, but not specifically for calcium absorption. Vitamin C (choice B) is essential for collagen production and immune function, but not directly related to calcium absorption. Vitamin E (choice D) is an antioxidant that helps protect cells from damage, but it is not primarily involved in calcium absorption like vitamin D.

5. Which term describes the ability of a substance to conduct electricity?

Correct answer: c

Rationale: Conductivity refers to a substance's ability to conduct electricity. Substances that conduct electricity well are known as conductors.
