1. Which type of reaction is represented by the equation A + B → AB?

• A. Synthesis
• B. Decomposition
• C. Single Replacement
• D. Double Replacement

Correct answer: a

Rationale: Synthesis reactions involve the combination of two or more substances to form a new compound.

2. According to Newton's third law of motion, if you push against a wall with a certain force, the wall will push back with:

• A. A smaller force
• B. An equal force
• C. A greater force
• D. No force at all

Correct answer: b

Rationale: Newton's third law states that for every action, there is an equal and opposite reaction.

3. Adaptive radiation refers to the evolutionary process where:

• A. A single ancestral species diversifies into multiple descendant species due to ecological pressures in a heterogeneous environment.
• B. Two unrelated species evolve similar adaptations in response to similar environments, leading to convergent evolution.
• C. A population becomes increasingly well-adapted to its current environment through continued natural selection.
• D. The fossil record exhibits gaps or missing links in the evolutionary history of a lineage.

Correct answer: A

Rationale: Rationale: - Adaptive radiation is a process where a single ancestral species diversifies into multiple descendant species to exploit different ecological niches within a heterogeneous environment. - This diversification occurs due to the different selective pressures present in various habitats, leading to the evolution of distinct traits and adaptations in different descendant species. - Option A accurately describes the process of adaptive radiation, where the initial species undergoes rapid speciation to occupy different ecological roles and adapt to diverse environmental conditions. - Options B, C, and D do not accurately describe adaptive radiation but refer to other evolutionary processes such as convergent evolution, natural selection, and gaps in the fossil record, respectively.

4. A solution is formed when:

• A. One substance dissolves in another
• B. Two or more substances react chemically
• C. A solid changes to a liquid
• D. None of the above

Correct answer: A

Rationale: One substance dissolves in another. A solution is a homogeneous mixture where one substance (solute) dissolves in another (solvent).

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

• A. Collaborates with the physician
• B. Provides care to a group of patients together with a group of nurses
• C. Provides care for 5-6 patients during their hospital stay.
• D. Performs comprehensive initial assessment

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. In the sentence "The house was dilapidated," what effect does the word "dilapidated" have on the reader's understanding?

• A. Creates a sense of mystery.
• B. Emphasizes the large size of the house.
• C. Suggests the house is in poor condition.
• D. Implies the house is haunted.

Correct answer: C

Rationale: The word "dilapidated" specifically describes the house's deteriorating state.
