English Grammar

1. How do you spell the past participle of the verb "lie" (to recline)?

Correct answer: B

Rationale: The past participle of "lie" (to recline) is "lain," not "lied," which is the past tense.

2. What is the Pauli exclusion principle?

Correct answer: B

Rationale: The Pauli exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers. This means that electrons in the same orbital must have opposite spins, which is why they cannot be in the same orbital with the same spin. Option A refers to the Aufbau principle, option C refers to the maximum number of electrons in an orbital based on the formula 2n^2, and option D refers to Coulomb's law, which describes the electrostatic force between charged particles.

3. What happens during a physical change in matter?

Correct answer: C

Rationale: During a physical change in matter, the original substance undergoes a change in its physical state or appearance without any change in its chemical composition. This means that the original substance can be recovered by physical means, such as melting, freezing, boiling, or condensing. No new substance is formed (option A), the chemical composition remains the same (option B), and energy changes can occur but are not a defining characteristic of a physical change (option D).

4. What is the term for a solution that has exactly the same concentration of solute as another solution?

Correct answer: c

Rationale: An isotonic solution has the same concentration of solute as another solution. The other choices do not accurately describe an isotonic solution.

5. Which of the following is NOT a type of epithelium

Correct answer: D

Rationale: The correct answer is D, 'Stratified columnar.' Epithelial tissues are classified based on their structure and function. Stratified squamous epithelium consists of multiple layers of flattened cells and is found in areas that need protection, like the skin. Simple cuboidal epithelium is a single layer of cube-shaped cells that function in secretion and absorption, commonly found in kidney tubules. Stratified columnar epithelium is a rare type with multiple layers of column-shaped cells, primarily found in the male urethra. Since 'Stratified columnar' is a valid type of epithelium, it is NOT the correct answer for this question.

6. During which phase of the cardiac cycle do the atria contract, pushing blood into the ventricles?

Correct answer: C

Rationale: The correct answer is C: Atrial systole. During the cardiac cycle, the atria contract during atrial systole, pushing blood into the ventricles. This phase occurs after atrial diastole when the atria fill with blood. Ventricular diastole (option D) is when the ventricles relax and fill with blood, preparing for ventricular systole (option B), which is when the ventricles contract to pump blood out of the heart. Atrial systole is crucial for ensuring efficient filling of the ventricles before they contract, making it a key phase in the cardiac cycle.
