English Grammar
1. What is the function of the underlined phrase "with a mischievous grin" in the sentence "He approached her with a mischievous grin, his eyes twinkling"?
- A. Subject
- B. Direct object
- C. Adverbial phrase
- D. Appositive phrase
Correct answer: C
Rationale: The underlined phrase modifies the verb "approached" by describing his manner, making it an adverbial phrase.
2. Which word is spelled correctly?
- A. Accomodate
- B. Acquiesce
- C. Percieve
- D. Dilema
Correct answer: B
Rationale: Option B is the correct spelling for "to submit or agree without protest."
3. Elements tend to gain or lose electrons to achieve stable electron configurations like those of noble gases. Their group number often indicates the number of electrons gained/lost and the resulting ionic charge, providing a good starting point for prediction.
- A. Ionic bonds involve electron sharing, while metallic bonds involve electron transfer
- B. Ionic bonds are weak and directional, while metallic bonds are strong and non-directional
- C. Ionic bonds exist between metals and non-metals, while metallic bonds exist only between metals
- D. Ionic bonds form discrete molecules, while metallic bonds form extended structures
Correct answer: D
Rationale: Ionic bonds involve complete electron transfer between atoms, creating strong, non-directional electrostatic attraction. Metallic bonds involve a delocalized "sea" of electrons shared across all metal atoms, resulting in a strong, extended structure.
4. The inability of the kidneys to effectively filter waste products from the blood is called:
- A. Dehydration
- B. Kidney failure
- C. Incontinence
- D. Nephritis
Correct answer: B
Rationale: The correct answer is B: "Kidney failure." Kidney failure refers to the inability of the kidneys to effectively filter waste products from the blood, leading to a buildup of toxins in the body. Dehydration, option A, is the state of lacking adequate fluid in the body and is not specifically related to kidney function. Incontinence, option C, is the loss of bladder control and is unrelated to kidney filtration function. Nephritis, option D, specifically refers to inflammation of the kidneys and may not always result in complete kidney failure. Therefore, the most appropriate answer for the described scenario is B.
5. The involuntary "fight-or-flight" response is controlled by the:
- A. Sympathetic nervous system
- B. Parasympathetic nervous system
- C. Enteric nervous system
- D. Sensory nervous system
Correct answer: A
Rationale: The correct answer is A: Sympathetic nervous system. The "fight-or-flight" response is an automatic physiological reaction triggered by the sympathetic nervous system in response to a perceived threat or stressor. This system prepares the body for action by increasing heart rate, dilating pupils, and redirecting blood flow to muscles. The parasympathetic nervous system, on the other hand, controls the body's "rest-and-digest" response, promoting relaxation and digestion. The enteric nervous system primarily regulates the gastrointestinal system, while the sensory nervous system is responsible for transmitting sensory information to the brain. Therefore, the sympathetic nervous system is specifically responsible for initiating the fight-or-flight response.
6. Immunoglobulin G (IgG) is the most abundant antibody type, responsible for:
- A. Immediate allergic reactions
- B. Neutralizing toxins and viruses
- C. Activating other immune cells
- D. Protecting newborns from infections
Correct answer: B
Rationale: The correct answer is B: 'Neutralizing toxins and viruses.' Immunoglobulin G (IgG) is the most abundant antibody type in the blood and tissues. It plays a crucial role in neutralizing toxins and viruses by binding to them and marking them for destruction by other immune cells. IgG is also involved in opsonization, which enhances phagocytosis of pathogens by immune cells. While IgE is primarily responsible for immediate allergic reactions, IgG's main functions are related to immunity against pathogens rather than allergic responses. Activating other immune cells is typically associated with antibodies like IgM, while protecting newborns from infections is mainly attributed to maternal IgG antibodies passed on during pregnancy. Therefore, option B is the most accurate description of IgG's role in the immune system.
