1. Which type of fiber is insoluble and promotes gut motility?

• A. Pectin
• B. Cellulose
• C. Beta-gluca
• D. Guar gum

Correct answer: B

Rationale: Rationale: A) Pectin is a soluble fiber found in fruits and vegetables. It forms a gel-like substance in the gut and can help lower cholesterol levels. B) Cellulose is an insoluble fiber found in plants, particularly in the cell walls of fruits, vegetables, and whole grains. It adds bulk to the stool and promotes gut motility by aiding in the movement of food through the digestive system. C) Beta-glucan is a soluble fiber found in oats and barley. It can help lower cholesterol levels and improve blood sugar control. D) Guar gum is a soluble fiber derived from guar beans. It can help with digestion and may have a role in managing blood sugar levels. In this case, the question specifically asks for the type of fiber that is insoluble and promotes gut motility, which is characteristic of cellulose.

2. A study finds a link between increased screen time and lower academic performance. What additional information would be most helpful in interpreting this finding?

• A. The average socioeconomic status of the study participants.
• B. The specific types of screen activities participants engaged in.
• C. Whether the students had access to healthy meals and snacks.
• D. The participants' ages and grade levels.

Correct answer: B

Rationale: Knowing the specific types of screen activities participants engaged in would provide crucial context for interpreting the link between increased screen time and lower academic performance. For example, if the majority of screen time was spent on educational apps or programs, the impact on academic performance may differ compared to if the screen time was mostly spent on social media or gaming. Understanding the nature of screen activities can help determine the potential mechanisms behind the observed relationship.

3. 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.

4. A scientific theory is:

• A. A personal belief or hunch about how something works.
• B. A well-substantiated explanation based on evidence and repeated testing.
• C. A single experiment's findings not yet confirmed by others.
• D. A fixed and unchanging dogma beyond questioning.

Correct answer: B

Rationale: Theories in science are constantly evolving and open to revision as new data emerges, unlike personal beliefs or fixed dogmas.

5. Which phase of the employment process includes getting on the payroll and completing

• A. Orientation
• B. Induction
• C. Selection
• D. Recruitment

Correct answer: D

Rationale: The correct answer is D: Recruitment. Recruitment is the phase of the employment process where organizations actively seek out and attract potential candidates for job openings. This involves advertising the position, sourcing candidates, and conducting initial screenings. Once the recruitment process is complete and a candidate has been selected, they move on to the selection phase. Orientation, on the other hand, occurs after a candidate has been hired and involves familiarizing the new employee with the organization, its policies, and their role. Induction is often used interchangeably with orientation and refers to the process of integrating a new employee into the organization. Therefore, in this context, recruitment is the most appropriate phase that involves getting on the payroll and completing the initial steps to bring a new employee on board.

6. What type of bond forms between elements when they share electrons?

• A. Covalent bond
• B. Ionic bond
• C. Metallic bond
• D. Hydrogen bond

Correct answer: A

Rationale: In a covalent bond, atoms share electrons, creating a strong attraction that holds them together
