1. What is equivalent to 1 L?

• A. 1 kilogram
• B. 1 quart
• C. 1 milliliter
• D. 1000 milliliters

Correct answer: D

Rationale: 1 liter is equivalent to 1000 milliliters. This conversion is based on the fact that 1 liter equals 1000 milliliters, a standard metric relationship. Choice A is incorrect because a kilogram is a unit of mass, not volume. Choice B, 1 quart, is a non-metric unit of volume and is not equivalent to 1 liter. Choice C, 1 milliliter, is too small to be equivalent to 1 liter; it takes 1000 milliliters to make up 1 liter.

2. Which property of a wave remains constant when the wave enters a different medium?

• A. Frequency
• B. Wavelength
• C. Amplitude
• D. Speed

Correct answer: A

Rationale: When a wave enters a different medium, its frequency remains constant. Frequency is an intrinsic property of the wave determined by its source, and it does not change when transitioning between different mediums. On the other hand, wavelength, amplitude, and speed of the wave can all be altered when the wave moves from one medium to another. Wavelength is dependent on the speed of the wave and can change when entering a different medium due to differences in propagation speed. Amplitude can also change as it is influenced by factors like energy loss or gain at the boundary of the mediums. Speed, determined by the medium's properties, typically changes when a wave transitions between different mediums due to variations in the medium's density and elasticity.

3. What type of genetic testing can reveal an individual's susceptibility to certain diseases?

• A. Karyotyping
• B. Pharmacogenomics
• C. Paternity testing
• D. Microarray analysis

Correct answer: D

Rationale: A) Karyotyping is a genetic test that examines an individual's chromosomes to detect abnormalities such as extra or missing chromosomes. It is not typically used to reveal an individual's susceptibility to certain diseases. B) Pharmacogenomics is the study of how genes affect a person's response to drugs. It focuses on how genetic variations can influence drug response, rather than susceptibility to diseases. C) Paternity testing is a genetic test used to determine the biological relationship between a child and an alleged father. It is not used to reveal an individual's susceptibility to diseases. D) Microarray analysis is a type of genetic testing that can reveal an individual's susceptibility to certain diseases by analyzing variations in their DNA. It can identify genetic markers associated with increased risk for specific conditions, allowing for personalized risk assessment and preventive measures.

4. Which of the following is a pair of nerves that originates from the brain?

• A. Spinal nerves
• B. Olfactory nerves
• C. Sciatic nerve
• D. Optic nerve

Correct answer: B

Rationale: The olfactory nerves, choice B, are a pair of cranial nerves that originate from the brain. They are responsible for the sense of smell and are the only cranial nerves that directly connect to the cerebrum. Spinal nerves, choice A, originate from the spinal cord, the sciatic nerve, choice C, is a large nerve that originates in the lower back, and the optic nerve, choice D, originates from the retina of the eye. Therefore, choices A, C, and D are incorrect as they do not originate directly from the brain.

5. What part of speech is the word 'results' in the sentence 'The students eagerly awaited the results'?

• A. Verb
• B. Noun
• C. Adjective
• D. Adverb

Correct answer: B

Rationale: In this sentence, 'results' is the direct object of the verb 'awaited,' functioning as a noun. Hence, option B, 'Noun,' is correct. The students were eagerly waiting for what? The results - which makes 'results' a noun in this context. Choices A, C, and D are incorrect. 'Results' is not describing a verb, an adjective, or an adverb in the sentence; it is the object of the students' anticipation, indicating a noun.
