Anatomy

1. Which vitamin is essential for calcium absorption and bone health?

Correct answer: C

Rationale: The correct answer is Vitamin D. Vitamin D plays a crucial role in calcium absorption in the intestines, which is essential for maintaining strong and healthy bones. It helps regulate calcium and phosphorus levels in the body, promoting bone mineralization and growth. Vitamin A is important for vision and immune function, not specifically for bone health. Vitamin C is essential for collagen synthesis but not directly involved in calcium absorption. Vitamin E is an antioxidant that protects cells from damage but does not have a direct role in bone health. Therefore, Vitamin D is the correct choice for supporting calcium absorption and bone health.

2. What is the process of converting lactic acid back into pyruvate called?

Correct answer: C

Rationale: Rationale: A) Glycolysis is the process of breaking down glucose into pyruvate. B) Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources. C) The Cori cycle is the process by which lactic acid produced by anaerobic metabolism in muscles is transported to the liver and converted back into glucose or pyruvate. D) Oxidative phosphorylation is the process by which ATP is synthesized using energy derived from the transfer of electrons in the electron transport chain.

3. What type of force opposes the motion of an object moving through a fluid (liquid or gas)?

Correct answer: c

Rationale: Viscous force is the resistance experienced by an object moving through a fluid due to internal friction.

4. Which of the following is NOT a part of a plant cell?

Correct answer: D

Rationale: Rationale: A) Cell wall: This is a structure found in plant cells that provides support and protection. B) Plasma membrane: Also known as the cell membrane, it surrounds the cell and regulates the passage of substances in and out of the cell. C) Vacuole: This is a storage organelle found in plant cells that stores water, nutrients, and waste products. D) Mitochondria: Mitochondria are membrane-bound organelles found in both plant and animal cells. They are responsible for producing energy in the form of ATP through cellular respiration. Therefore, the correct answer is D) Mitochondria, as it is a part of a plant cell.

5. What is the name of the structure that packages DNA in eukaryotic cells?

Correct answer: A

Rationale: Rationale: - A nucleosome is the basic structural unit of DNA packaging in eukaryotic cells. It consists of DNA wrapped around a core of histone proteins. - Chromatin refers to the complex of DNA and proteins found in the nucleus of a eukaryotic cell, including nucleosomes. - Histones are the proteins around which DNA is wrapped to form nucleosomes. - Centromere is a region of a chromosome where the two sister chromatids are joined and to which spindle fibers attach during cell division.

6. Julius plans to revisit the organizational chart of the department. He plans to create a new

Correct answer: B

Rationale: The correct answer is B: 'Solid line.' In organizational charts, solid lines typically represent formal reporting relationships, indicating direct authority and responsibility between positions. Creating a new solid line on the chart would signify a new formal reporting relationship within the department. This can be important for clarifying roles, communication channels, and decision-making processes. Boxes represent positions or roles in the organizational structure, while broken lines and dotted lines are typically used for informal relationships or advisory roles, rather than formal reporting relationships.
