English Grammar
1. Which phrase best describes the tone of the following sentence: "He slammed his fist on the table, his voice booming with anger."
- A. Playful
- B. Formal
- C. Agitated
- D. Melancholy
Correct answer: C
Rationale: The verbs and descriptive language convey strong emotions and agitation.
2. Which of the following is NOT a function of the nervous system?
- A. Detecting touch
- B. Regulating body temperature
- C. Producing insulin
- D. Controlling muscle movement
Correct answer: C
Rationale: The correct answer is C: 'Producing insulin.' The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Insulin production is actually regulated by the endocrine system, specifically the pancreas. Insulin helps regulate blood sugar levels, which is not a function of the nervous system. It is important to differentiate between the roles of the nervous system and the endocrine system in maintaining bodily functions.
3. 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.
4. What is the main function of the endoplasmic reticulum (ER) in the cell?
- A. To synthesize and transport proteins and lipids
- B. To package and transport proteins
- C. To break down macromolecules
- D. To store genetic material
Correct answer: A
Rationale: Rationale: A) The endoplasmic reticulum (ER) is a network of membranes within the cell that plays a crucial role in protein and lipid synthesis. It consists of two types: rough ER, which is studded with ribosomes and involved in protein synthesis, and smooth ER, which is involved in lipid synthesis and detoxification. The ER also plays a role in transporting these synthesized proteins and lipids to other parts of the cell or outside the cell. B) While the ER is involved in packaging proteins, the main function is not solely to package and transport proteins. This function is more associated with the Golgi apparatus. C) Breaking down macromolecules is primarily the function of lysosomes, which are membrane-bound organelles containing enzymes for digestion. D) Storing genetic material is the function of the nucleus, which houses the cell's DNA. The ER is not involved in storing
5. The body's first line of defense against pathogens includes:
- A. Phagocytes
- B. Antibodies
- C. Memory B cells
- D. T lymphocytes
Correct answer: A
Rationale: Rationale: Phagocytes are a type of white blood cell that plays a crucial role in the body's innate immune response, which is the first line of defense against pathogens. Phagocytes engulf and digest foreign particles, such as bacteria and viruses, helping to prevent infection and disease. Antibodies (option B) are produced by B cells and are part of the adaptive immune response, not the first line of defense. Memory B cells (option C) are also part of the adaptive immune response and are involved in mounting a faster and stronger response upon re-exposure to a pathogen. T lymphocytes (option D) are another type of white blood cell involved in the adaptive immune response, specifically in cell-mediated immunity.
6. The innate immune system provides a non-specific first line of defense. What are some physical barriers that contribute to the innate immune system?
- A. Antibodies
- B. Phagocytes
- C. Skin and mucous membranes
- D. Memory B cells
Correct answer: C
Rationale: The correct answer is C: "Skin and mucous membranes." The innate immune system consists of physical barriers, such as the skin and mucous membranes, that act as the first line of defense against pathogens. These barriers prevent pathogens from entering the body and play a crucial role in protecting against infections. Antibodies (option A) are part of the adaptive immune response, not the innate immune system. Phagocytes (option B) are cells that engulf and destroy pathogens, which are part of the innate immune system. Memory B cells (option D) are specific to the adaptive immune response and are not considered part of the innate immunity that provides the initial, non-specific defense.
