Biology

1. Which of the following phases of mitosis is characterized by the separation of sister chromatids and their movement to opposite poles?

Correct answer: B

Rationale: Rationale: During anaphase of mitosis, the sister chromatids, which are duplicated copies of a chromosome, separate and move towards opposite poles of the cell. This movement is facilitated by the shortening of microtubules attached to the chromatids. As a result, each pole of the cell receives a complete set of chromosomes, ensuring that the daughter cells produced after cell division will have the correct number of chromosomes. Metaphase is characterized by the alignment of chromosomes at the cell's equator, not their separation. Telophase is the phase following anaphase, where the separated chromatids reach the opposite poles and nuclear envelopes start to form around them. Cytokinesis is the final stage of cell division, where the cytoplasm is divided to form two separate daughter cells.

2. A book slides across a table. What determines the magnitude of the frictional force acting on the book?

Correct answer: C

Rationale: Both the mass of the book and the normal force from the table. Friction is proportional to both the normal force and the coefficient of friction, which depends on the materials in contact. Since the normal force depends on the weight of the object (mass x gravity), both factors are important.

3. Which phrase best describes the tone of the following sentence: "He slammed his fist on the table, his voice booming with anger."

Correct answer: C

Rationale: The verbs and descriptive language convey strong emotions and agitation.

4. The speed of light in a vacuum is measured in units of:

Correct answer: A

Rationale: The correct answer is A: 'Meters per second.' The speed of light in a vacuum is a fundamental constant of nature and is approximately 299,792,458 meters per second. This speed is constant and does not vary based on the frequency or wavelength of light. Hertz (B) is a unit of frequency, Candela (C) is a unit of luminous intensity, and Newton (D) is a unit of force. Understanding the units used to measure the speed of light is important in physics and related fields to accurately describe the propagation of light in different mediums.

5. Aubrey thinks about primary nursing as a system to deliver care. Which of the following

Correct answer: D

Rationale: Primary nursing is a care delivery system where one nurse is responsible for the total nursing care needs of a group of patients throughout their hospital stay. This includes performing comprehensive initial assessments, developing care plans, coordinating with other healthcare team members, and providing direct patient care. Option D is the correct answer as it aligns with the core principles of primary nursing, emphasizing the nurse's role in conducting thorough assessments to ensure individualized and holistic care for each patient in their caseload. Options A, B, and C do not accurately reflect the key components of primary nursing, making them incorrect choices.

6. The neutral theory of molecular evolution proposes that:

Correct answer: A

Rationale: Rationale: A) The neutral theory of molecular evolution, proposed by Motoo Kimura in the 1960s, suggests that the majority of mutations that occur in DNA are selectively neutral, meaning they do not have a significant impact on an organism's fitness. These neutral mutations are not subject to natural selection and are allowed to accumulate in populations over time. This theory helps explain the high levels of genetic variation observed within populations. B) Option B is incorrect because not all mutations are beneficial. Mutations can be neutral, harmful, or beneficial, and the neutral theory specifically focuses on the idea that many mutations are neutral in their effects. C) Option C is incorrect because the neutral theory suggests that evolution is not primarily driven by strong directional selection pressures. Instead, it emphasizes the role of genetic drift and the accumulation of neutral mutations in shaping genetic variation. D) Option D is incorrect because
