Reading

1. Based on the passage, which statement is MOST likely to be true about the author's stance on social media?

Correct answer: B

Rationale: The emphasis on critical thinking and responsible online behavior suggests an acknowledgment of social media's potential while advocating for addressing its downsides, aligning with B.

2. What is the primary function of the myelin sheath that surrounds some axons in the nervous system?

Correct answer: c

Rationale: The primary function of the myelin sheath that surrounds some axons in the nervous system is to speed up the transmission of nerve impulses. The myelin sheath acts as an insulating layer, which helps nerve impulses travel faster along the axon by allowing them to 'jump' from one node of Ranvier to the next, a process known as saltatory conduction. This increases the efficiency and speed of signal transmission, enabling rapid communication within the nervous system. Therefore, option C is the correct answer as it accurately describes the role of the myelin sheath in enhancing the speed of nerve impulse transmission.

3. How does an increase in mass affect the force required to produce the same acceleration on an object?

Correct answer: a

Rationale: With an increase in mass, more force is needed to produce the same acceleration due to inertia.

4. Stephanie is a new Staff Educator of a private tertiary hospital. She conducts orientation

Correct answer: D

Rationale: The correct answer is D, 'Manual of procedures.' During orientation, Stephanie as a Staff Educator would likely refer to the manual of procedures to provide new employees with detailed instructions on how to perform their job duties. This manual outlines the specific procedures, protocols, and guidelines that employees are expected to follow within the organization. It serves as a valuable resource for new hires to understand the standard operating procedures and expectations within the hospital setting, making it a crucial document to reference during orientation.

5. Which property of a substance refers to its ability to be stretched into thin wires?

Correct answer: c

Rationale: Ductility refers to a substance's ability to be stretched into thin wires without breaking.

6. What is the "lock-and-key" model?

Correct answer: B

Rationale: Rationale: The "lock-and-key" model is a concept used to describe the specificity of the interaction between enzymes and their substrates. In this model, the enzyme's active site is like a lock that can only be opened by the specific substrate molecule, which acts as the key. This specific binding ensures that enzymes catalyze specific reactions and do not interact with other molecules indiscriminately. Protein folding (option A) refers to the process by which a protein adopts its functional three-dimensional structure, but it is not specifically related to the lock-and-key model. Muscle contraction (option C) and blood clotting (option D) are biological processes that involve complex mechanisms but are not directly related to the lock-and-key model of enzyme-substrate interaction.
