Anatomy

1. The liver plays a vital role in digestion. What is one of the main functions of the liver in the digestive system?

Correct answer: C

Rationale: The correct answer is C: 'Storage and processing of nutrients.' The liver is a crucial organ in the digestive system as it performs various functions such as storing nutrients like glucose, vitamins, and minerals, processing nutrients by converting them into usable forms for the body, and regulating their distribution to different parts of the body. While the physical breakdown of food primarily occurs in the mouth and stomach, and the production of digestive enzymes mainly happens in the pancreas and small intestine, the liver's main role is to manage and store the nutrients obtained from the digested food. Therefore, option C is the correct choice for the main function of the liver in the digestive process.

2. What is the difference between a prokaryotic cell and a eukaryotic cell?

Correct answer: B

Rationale: Rationale: - Prokaryotic cells are simpler and do not have a true nucleus. Their genetic material is located in the nucleoid region, which is not enclosed by a membrane. - Eukaryotic cells are more complex and have a true nucleus that houses the genetic material, enclosed within a nuclear membrane. - Both prokaryotic and eukaryotic cells have organelles, but eukaryotic cells have membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, while prokaryotic cells lack these membrane-bound organelles.

3. She tries to design an organizational structure that allows communication to flow in all

Correct answer: A

Rationale: The correct answer is 'A: Centralized.' In a centralized organizational structure, decision-making authority and communication flow through a single point of control or a specific group of individuals. This setup ensures that communication channels are streamlined and information is disseminated efficiently. By designing an organizational structure that allows communication to flow in all directions, it suggests a decentralized structure where decision-making authority is distributed across various levels and departments. Therefore, 'Centralized' is the best fit for the scenario described in the question.

4. Which sentence uses the word "literally" correctly?

Correct answer: B

Rationale: Option B uses "literally" to emphasize the magnitude of work, not to exaggerate a simple action.

5. What does the term "dilution" refer to in a solution?

Correct answer: A

Rationale: Dilution involves adding more solvent to a solution to decrease the concentration of solute. The other choices do not accurately describe dilution

6. Lymph nodes are small, bean-shaped structures found along lymphatic vessels. What is their primary function?

Correct answer: C

Rationale: The correct answer is C. Lymph nodes are crucial components of the immune system. Their primary function is to filter lymph, which is a clear fluid containing white blood cells, and to fight off infections. Lymph nodes contain specialized cells that help trap and destroy pathogens, such as bacteria and viruses, that may be present in the lymph fluid. This process helps to prevent the spread of infections throughout the body and plays a key role in maintaining overall immune function. Therefore, option C, 'To filter lymph and fight infection,' is the most appropriate description of the primary function of lymph nodes.
