Mathematics

1. A patient's temperature is measured as 38.5 degrees Celsius. What is their temperature in Fahrenheit?

Correct answer: A

Rationale: Use the conversion formula: °F = (°C x 9/5) + 32. Substitute 38.5°C for °C and calculate: (38.5°C x 9/5) + 32 ≈ 99.5°F.

2. What is the main consequence of a malfunctioning thyroid gland that produces abnormally low levels of thyroid hormones?

Correct answer: B

Rationale: The correct answer is B: 'Decreased heart rate and body temperature.' When the thyroid gland produces abnormally low levels of thyroid hormones (hypothyroidism), it can lead to a decrease in metabolic rate, resulting in symptoms such as fatigue, weight gain, and feeling cold. A lower metabolic rate can slow down heart rate and decrease body temperature. The other options (A, C, D) are not characteristic of hypothyroidism. Increased energy levels and weight loss, enhanced muscle growth and bone development, and faster metabolism and heightened alertness are more commonly associated with hyperthyroidism, where the thyroid gland produces excess hormones.

3. Which of the following is the smallest unit of matter?

Correct answer: B

Rationale: An atom is the fundamental building block of matter, while molecules are formed by the combination of atoms.

4. Which sentence uses the present perfect continuous tense correctly?

Correct answer: A

Rationale: Option A emphasizes the ongoing action (working) that started in the past and continues to the present.

5. A population refers to a group of organisms of the same:

Correct answer: A

Rationale: In ecology, a population is a specific group of organisms of the same species living in a particular geographic area at a given time. They share a common gene pool and interact with each other and their environment.

6. What is the primary function of the epiglottis in the respiratory system?

Correct answer: C

Rationale: The primary function of the epiglottis in the respiratory system is to prevent food from entering the trachea. When we swallow, the epiglottis covers the opening to the trachea, directing food and liquids to the esophagus instead of the airway. This action helps to protect the respiratory system from foreign objects that could obstruct airflow and cause choking or aspiration pneumonia. Filtration of air and production of mucus are functions associated with other respiratory structures like the nasal passages and bronchial tubes, while oxygen exchange in the alveoli occurs in the lungs, not the epiglottis.
