1. What is the final stage of both mitosis and meiosis?

• A. Interphase
• B. Telophase
• C. Cytokinesis
• D. G1 phase

Correct answer: B

Rationale: Rationale: - Interphase (option A) is not the final stage of mitosis or meiosis; it is the phase before cell division where the cell prepares for division by growing and replicating its DNA. - Telophase (option B) is the final stage of both mitosis and meiosis. During telophase, the separated chromosomes reach opposite poles of the cell, the nuclear membrane reforms around each set of chromosomes, and the chromosomes begin to decondense. - Cytokinesis (option C) is the process of dividing the cytoplasm to form two separate daughter cells. While it occurs after telophase, it is not considered the final stage of mitosis or meiosis. - G1 phase (option D) is the first gap phase in the cell cycle, occurring before DNA replication. It is not the final stage of mitosis or meiosis.

2. What is the name of the condition characterized by inflammation of the small intestine?

• A. Appendicitis
• B. Celiac disease
• C. Gastritis
• D. Crohn's disease

Correct answer: D

Rationale: Rationale: A) Appendicitis is inflammation of the appendix, not the small intestine. B) Celiac disease is an autoimmune disorder triggered by gluten consumption that damages the small intestine, but it is not characterized by inflammation alone. C) Gastritis is inflammation of the stomach lining, not the small intestine. D) Crohn's disease is a chronic inflammatory condition that can affect any part of the gastrointestinal tract, but it commonly involves the small intestine. Symptoms of Crohn's disease include abdominal pain, diarrhea, weight loss, and fatigue.

3. In the process of cellular respiration, glucose is broken down to produce energy. What is the main waste product released?

• A. Water
• B. Carbon dioxide
• C. Oxygen
• D. Protein

Correct answer: B

Rationale: The correct answer is B: Carbon dioxide. During cellular respiration, glucose is broken down in the presence of oxygen to produce energy in the form of ATP. One of the main waste products released in this process is carbon dioxide. Carbon dioxide is a byproduct of the metabolic reactions occurring in cells and is expelled from the body through exhalation. Water is also produced during cellular respiration, but it is not the main waste product released. Oxygen is required for cellular respiration to occur, and protein is a macromolecule and not a waste product of cellular respiration.

4. What is the name of the white blood cells that attack foreign invaders?

• A. Phagocytes
• B. Lymphocytes
• C. Platelets
• D. Red blood cells

Correct answer: A

Rationale: Rationale: Phagocytes are a type of white blood cell that plays a crucial role in the immune system by engulfing and digesting foreign invaders such as bacteria, viruses, and other harmful substances. They are part of the body's innate immune response and are essential for protecting the body against infections. Lymphocytes, on the other hand, are another type of white blood cell involved in the adaptive immune response, producing antibodies and coordinating immune responses. Platelets are cell fragments involved in blood clotting, while red blood cells are responsible for carrying oxygen to tissues.

5. What is the SI unit of measurement for work?

• A. Newton-meter (N·m)
• B. Joule (J)
• C. Watt (W)
• D. Meter per second (m/s)

Correct answer: b

Rationale: Work is measured in Joules (J) in the SI unit system.

6. Define work in physics.

• A. Force applied to an object at rest
• B. Force exerted by an object in motion
• C. Transfer of energy through motion along a direction
• D. Measure of an object's potential energy

Correct answer: c

Rationale: Work in physics is the transfer of energy when a force is applied and the object moves in the direction of the force.
