1. What is the term for a genetic disorder caused by a mutation in a mitochondrial gene?

Correct answer: D

Rationale: Rationale: A) Autosomal dominant disorder: This type of genetic disorder is caused by a mutation in one copy of an autosomal gene. It is not related to mitochondrial gene mutations. B) Autosomal recessive disorder: This type of genetic disorder is caused by mutations in both copies of an autosomal gene. It is not related to mitochondrial gene mutations. C) Sex-linked disorder: This type of genetic disorder is caused by mutations in genes located on the sex chromosomes (X or Y). It is not related to mitochondrial gene mutations. D) Mitochondrial disorder: Mitochondrial disorders are genetic disorders caused by mutations in genes located in the mitochondria, the energy-producing structures within cells. These disorders are inherited maternally and can affect various organs and systems in the body due to the role of mitochondria in energy production.

2. Which property describes a substance's resistance to flow?

Correct answer: b

Rationale: Viscosity refers to a substance's resistance to flow. Substances with high viscosity flow slowly, while those with low viscosity flow more easily.

3. Antidiuretic hormone (ADH) helps the kidneys regulate:

Correct answer: C

Rationale: The correct answer is C: 'Urine output by controlling water reabsorption.' Antidiuretic hormone (ADH) is released by the pituitary gland and acts on the kidneys to regulate water reabsorption. When ADH levels are high, the kidneys reabsorb more water, leading to concentrated urine and decreased urine output. This helps maintain the body's water balance and prevent dehydration. While ADH indirectly influences blood pressure by regulating blood volume, its primary function is to control water balance, not acid-base balance. Therefore, the correct answer is C.

4. The author's tone towards UBI can be described as

Correct answer: D

Rationale: The passage acknowledges both positive and negative aspects of UBI, suggesting a cautious and balanced perspective, aligning with D.

5. What is the term for the distance between the center of a lens or curved mirror and its focal point?

Correct answer:

Rationale: The focal length of a lens or curved mirror is the distance between its center and the focal point, where parallel light rays converge or appear to diverge from.

6. What is the function of the pericardium, the sac surrounding the heart?

Correct answer: D

Rationale: The pericardium, the sac surrounding the heart, serves primarily to protect the heart and anchor it in place. It acts as a protective barrier against external infections or damage and helps to maintain the heart's position within the chest cavity. Additionally, the pericardium also provides some degree of shock absorption to minimize physical trauma to the heart. While the heart's electrical impulses for contraction originate from within the heart itself and are not generated by the pericardium, it does not play a role in directly generating these impulses. Therefore, option D, 'To protect the heart and anchor it in place,' is the correct function of the pericardium.
