Biology

1. Where does cellular respiration, the process of converting chemical energy into ATP, take place in eukaryotic cells?

Correct answer: C

Rationale: Rationale: Cellular respiration, the process of converting chemical energy into ATP, takes place in the mitochondria of eukaryotic cells. The mitochondria are known as the powerhouse of the cell because they are responsible for generating most of the cell's ATP through the process of cellular respiration. This process involves the breakdown of glucose and other organic molecules to produce ATP, which is the primary energy currency of the cell. The other organelles listed in the options (nucleus, ribosomes, and Golgi apparatus) do not play a direct role in cellular respiration.

2. Which of the following is the best approach to resolving conflicting scientific findings?

Correct answer: B

Rationale: When faced with conflicting scientific findings, the best approach is to conduct additional research to identify potential sources of discrepancies. This allows for a more thorough understanding of the topic and helps in resolving the conflicting findings through a scientific and evidence-based approach. Dismissing findings without further investigation, relying on prestige, or turning to media interpretations and public opinion can lead to misunderstandings and hinder scientific progress. Conducting additional research promotes a more comprehensive and accurate understanding of the subject matter.

3. What phenomenon explains the bending of light as it passes around an obstacle or through an aperture?

Correct answer: c

Rationale: Diffraction refers to the bending of light waves as they encounter an obstacle or pass through an aperture, causing the light to spread out.

4. She conducts a 6-month performance review session with a staff member. Which of the

Correct answer: C

Rationale: Option C is the correct answer because telling the staff that the session is manager-centered indicates that the focus will be on the manager's evaluation and feedback rather than promoting a collaborative and transparent review process. This approach can lead to a one-sided assessment and may not foster open communication or growth opportunities for the staff member. Options A and B involve bringing in another nurse, which could potentially compromise the privacy and effectiveness of the performance review. Option D, stating that the session is private between the two members, does not address the issue of the session being manager-centered. Therefore, option C is the most appropriate choice to highlight the importance of a balanced and inclusive performance review process.

5. What is the technical term for the involuntary muscular contractions that move food through the digestive tract?

Correct answer: B

Rationale: The correct answer is B: Peristalsis. Peristalsis is the coordinated, rhythmic contraction and relaxation of muscles in the digestive tract that propels food forward. This process helps move food through the esophagus, stomach, and intestines for digestion and absorption of nutrients. Segmentation (option A) is a different process involving alternating contractions in the intestines to mix food with digestive juices. Chylification (option C) is not a recognized term in digestion. Emulsification (option D) is the process of breaking down fats into smaller droplets for easier digestion, typically occurring in the small intestine with the help of bile. Therefore, peristalsis is the specific term for the involuntary muscular contractions responsible for moving food through the digestive tract.

6. Which of the following is the main function of the liver?

Correct answer: D

Rationale: Rationale: A) The liver does produce bile, which helps in the digestion of fats, but this is not its main function. Bile is stored in the gallbladder and released into the small intestine to aid in the digestion and absorption of fats. B) While the liver does store energy in the form of glycogen, this is not its main function. Glycogen is a form of glucose storage that can be broken down into glucose when the body needs energy. C) The liver does produce proteins that help to clot blood, such as fibrinogen and prothrombin, but this is not its main function. These proteins are essential for the blood clotting process to prevent excessive bleeding. D) The main function of the liver is to detoxify harmful substances in the body. The liver processes and removes toxins, drugs, alcohol, and other harmful substances from the bloodstream, making them less harmful and
