Biology

1. Explain how a single gene mutation can lead to multiple phenotypes depending on the organism.

Correct answer: A

Rationale: A single gene mutation can affect different biochemical pathways or developmental processes, leading to a cascade of downstream effects and diverse phenotypic consequences.

2. 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.

3. When Harry uses team nursing as a care delivery system, he and his team need to assess the

Correct answer: C

Rationale: When Harry uses team nursing as a care delivery system, he and his team need to assess the medications and treatments required for all patients. In team nursing, different team members are responsible for specific aspects of patient care, such as medications and treatments. Assessing the medications and treatments required for all patients ensures that each patient receives appropriate and timely care. This approach helps in coordinating care effectively among team members and prevents errors or omissions in patient treatment. Therefore, option C is the correct answer as it aligns with the principles of team nursing and patient-centered care.

4. Which form of energy is associated with the motion of an object?

Correct answer: a

Rationale: Kinetic energy is the energy of motion possessed by an object.

5. A group of antibiotics that target the cell wall of bacteria are classified as:

Correct answer: A

Rationale: Rationale: Penicillins are a group of antibiotics that target the cell wall of bacteria by inhibiting the synthesis of peptidoglycan, a key component of the bacterial cell wall. By interfering with cell wall synthesis, penicillins weaken the cell wall, leading to bacterial cell lysis and death. This mechanism of action makes penicillins effective against a wide range of bacteria, particularly Gram-positive bacteria. Tetracyclines (B), Macrolides (C), and Fluoroquinolones (D) have different mechanisms of action and do not specifically target the bacterial cell wall. Tetracyclines inhibit protein synthesis, Macrolides interfere with bacterial ribosomes, and Fluoroquinolones target bacterial DNA gyrase and topoisomerase IV.

6. The rigid structure that provides shape and support to plant cells is called the:

Correct answer: A

Rationale: The correct answer is A: Cell wall. The cell wall is a rigid structure found in plant cells, providing support and shape to the cell. It is composed mainly of cellulose, a tough and fibrous substance that helps plants maintain their structure. The plasma membrane, option B, is a semi-permeable membrane that surrounds the cell and regulates the passage of substances in and out of the cell. The nucleus, option C, is the control center of the cell that contains genetic material. Cytoplasm, option D, is the jelly-like substance that fills the cell and houses organelles. In this context, the function of providing shape and support points specifically to the cell wall, making it the correct choice.
