physics

1. How does the mass of an object affect its inertia?

Correct answer: B

Rationale: Inertia is the resistance of an object to changes in its state of motion. The greater the mass of an object, the greater its inertia because it requires more force to change its state of motion. This is in line with Newton's first law of motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force.

2. What is the role of RNA interference in silencing genes?

Correct answer: C

Rationale: Rationale: RNA interference (RNAi) is a biological process that involves the silencing of gene expression by inhibiting the translation of mRNA or by degrading mRNA molecules. This mechanism plays a crucial role in regulating gene expression and can be used to selectively silence specific genes. By interfering with the expression of specific genes, RNAi can downregulate protein production from those genes. Therefore, option C, "Inhibits the expression of specific genes," is the correct role of RNA interference in silencing genes.

3. On the other hand, Ms. Castro notices that the Chief Nurse Executive has charismatic

Correct answer: D

Rationale: The correct answer is D because matching leadership style to the situation at hand is a key aspect of effective leadership. Being able to adapt and adjust leadership approaches based on the specific circumstances and needs of a situation can lead to better outcomes and success. In this scenario, the Chief Nurse Executive's ability to tailor his leadership style to different situations is likely to contribute to his effectiveness in managing various challenges and leading the team effectively.

4. What is the difference between a germline mutation and a somatic mutation?

Correct answer: B

Rationale: Rationale: - Germline mutations are changes in the DNA of reproductive cells (sperm or egg cells) and can be passed on to offspring, affecting all cells in the resulting organism. - Somatic mutations are changes in the DNA of non-reproductive cells (body cells) and are not passed on to offspring. These mutations only affect the cells that arise from the mutated cell. - Option A is incorrect because somatic mutations are not passed to offspring. - Option C is incorrect because both germline and somatic mutations can affect any DNA. - Option D is incorrect because the effects of mutations, whether germline or somatic, can be beneficial, harmful, or have no significant impact.

5. In the reaction 2H2 + O2 → 2H2O, how many moles of oxygen are required to react completely with 4 moles of hydrogen?

Correct answer: 2

Rationale: The balanced equation indicates a 1:1 ratio between H2 and O2, so 4 moles of H2 require 4 moles of O2, and 2 moles of H2 require 2 moles of O2.

6. What is the main verb tense in the following sentence? "She had already left before I arrived."

Correct answer: D

Rationale: The verb "had left" is in the past perfect tense, indicating an action completed before another past action ("arrived").
