English Grammar
1. "Ironic" and "serious" are:
- A. synonyms (have the same meaning)
- B. antonyms (have opposite meanings)
- C. homonyms (sound the same but have different meanings)
- D. none of the above
Correct answer: B
Rationale: "Ironic" means the opposite of "serious."
2. What is the recommended daily fluid intake for adults?
- A. 1 liter
- B. 2 liters
- C. 3 liters
- D. 4 liters
Correct answer: B
Rationale: Rationale: The recommended daily fluid intake for adults is typically around 2 liters, which is equivalent to about 8 cups or half a gallon. This amount can vary depending on factors such as age, gender, weight, activity level, and climate. Staying adequately hydrated is essential for overall health and helps maintain proper bodily functions, such as regulating body temperature, aiding digestion, and transporting nutrients and oxygen throughout the body. Drinking enough fluids also helps prevent dehydration, which can lead to symptoms like fatigue, headaches, and dizziness. It's important to note that individual fluid needs may vary, so it's always best to consult with a healthcare provider for personalized recommendations.
3. Fluorescent microscopy utilizes which property of certain molecules to create a visible image?
- A. Staining properties
- B. Light absorption
- C. Fluorescence emission
- D. Refraction
Correct answer: C
Rationale: Rationale: Fluorescent microscopy relies on the property of certain molecules to fluoresce when exposed to specific wavelengths of light. When these molecules absorb light energy, they become excited and then emit light at a longer wavelength, producing a visible image. This emitted light is what is used to create the image in fluorescent microscopy, making option C, fluorescence emission, the correct answer. Staining properties (option A) are used to enhance contrast in microscopy but are not the primary mechanism in fluorescent microscopy. Light absorption (option B) is involved in the excitation of fluorescent molecules but is not the property used to create the visible image. Refraction (option D) is the bending of light as it passes through different mediums and is not the property utilized in fluorescent microscopy.
4. Which part of the spinal cord is responsible for transmitting sensory information from the body to the brain?
- A. Dorsal root
- B. Ventral root
- C. Gray matter
- D. White matter
Correct answer: a
Rationale: The correct answer is A: Dorsal root. The dorsal root of the spinal cord is responsible for transmitting sensory information from the body to the brain. This root contains sensory nerve fibers that carry information such as touch, temperature, and pain signals from the peripheral nervous system to the central nervous system. Ventral roots, on the other hand, are responsible for transmitting motor information from the brain to the muscles. Gray matter is primarily composed of nerve cell bodies and is involved in processing information, while white matter consists of myelinated nerve fibers that facilitate communication between different parts of the nervous system. Therefore, in this context, the dorsal root is the specific structure that handles sensory information transmission.
5. Which of the following is the main function of the heart?
- A. To filter blood
- B. To exchange gases
- C. To pump blood throughout the body
- D. To produce hormones
Correct answer: C
Rationale: Rationale: The main function of the heart is to pump blood throughout the body. The heart is a muscular organ that works as a pump to circulate blood, which carries oxygen and nutrients to the body's tissues and removes waste products. Option A is incorrect because the kidneys are responsible for filtering blood. Option B is incorrect because the exchange of gases, such as oxygen and carbon dioxide, occurs in the lungs. Option D is incorrect because hormone production is primarily carried out by endocrine glands such as the pituitary gland and the thyroid gland.
6. Which sentence uses the modal verb "should" correctly?
- A. You should have studied harder for the exam.
- B. I should be going now.
- C. She said she should have taken a different route.
- D. They should be arriving any minute now.
Correct answer: B
Rationale: Option B conveys an intention or expectation regarding the present or near future.
