1. She plans of assigning competent people to fill the roles designed in the hierarchy. Which

A. Staffing
B. Scheduling
C. Recruitment
D. Induction

Correct answer: B

Rationale: The correct answer is B: Scheduling. Scheduling involves assigning people to specific tasks or roles within an organization based on the hierarchy and operational needs. In this scenario, the focus is on assigning competent individuals to fill the roles outlined in the hierarchy, which aligns with the concept of scheduling. Staffing refers to the overall process of acquiring, deploying, and retaining a workforce; recruitment specifically pertains to attracting and selecting candidates for job roles; and induction involves the orientation and integration of new employees into the organization. Therefore, the most relevant term in this context is scheduling.

2. What does the term "solute" refer to in a solution?

A. The substance present in the largest amount
B. The substance that dissolves in the solvent
C. The liquid portion of the solution
D. The temperature at which the solution freezes

Correct answer: B

Rationale: The solute is the substance that dissolves in the solvent to form a solution. The other choices do not accurately describe the solute.

3. The microscopic units responsible for muscle contraction are called

A. Neurons
B. Myofibrils
C. Tendons
D. Sarcomeres

Correct answer: D

Rationale: The correct answer is D: Sarcomeres. Sarcomeres are the fundamental contractile units of skeletal muscle. They are composed of overlapping actin and myosin filaments that slide past each other during muscle contraction, resulting in muscle shortening. Neurons (A) are nerve cells that transmit signals to and from the brain. Myofibrils (B) are thread-like structures within muscle fibers that contain sarcomeres. Tendons (C) are fibrous connective tissues that attach muscles to bones, but they are not directly involved in muscle contraction like sarcomeres are.

4. What is the 3D structure of a protein called?

A. Tertiary structure
B. Secondary structure
C. Primary structure
D. Quaternary structure

Correct answer: A

Rationale: Rationale: - Primary structure refers to the linear sequence of amino acids in a protein. - Secondary structure refers to local folded structures within a protein, such as alpha helices and beta sheets. - Tertiary structure is the overall 3D shape of a protein, which is determined by interactions between amino acid side chains and the environment. - Quaternary structure refers to the arrangement of multiple protein subunits in a protein complex. Therefore, the 3D structure of a protein is called the tertiary structure because it represents the overall folding of the protein into a specific shape.

5. Which word is spelled correctly?

A. Accomodate
B. Acquiesce
C. Percieve
D. Dilema

Correct answer: B

Rationale: Option B is the correct spelling for "to submit or agree without protest."

6. What is the scientific term for a muscle that helps another muscle perform its action?

A. Agonist
B. Antagonist
C. Synergist
D. Fixator

Correct answer: C

Rationale: The correct answer is C: Synergist. A synergist muscle is a muscle that assists the prime mover (agonist) in performing its action by stabilizing joints or contributing extra force to the movement. Antagonist muscles oppose the action of the prime mover, while fixator muscles stabilize the origin of the prime mover to allow efficient movement. Understanding the roles of these muscles is essential in comprehending how various muscle groups work together to produce coordinated movements.
