Anatomy
1. What is the name of the condition characterized by swelling caused by a buildup of lymph fluid?
- A. Anemia
- B. Edema
- C. Hypertension
- D. Diabetes
Correct answer: B
Rationale: The correct answer is B: Edema. Edema is the condition characterized by swelling caused by a buildup of lymph fluid in the body's tissues. Anemia (A) is a condition characterized by a lack of healthy red blood cells, not swelling. Hypertension (C) is high blood pressure, which does not directly cause swelling. Diabetes (D) is a metabolic disorder affecting blood sugar levels and does not directly lead to lymph fluid buildup and swelling.
2. What type of clause is "as the sun dipped below the horizon" in the sentence "We sat on the beach, as the sun dipped below the horizon"?
- A. Independent clause
- B. Subordinate clause
- C. Appositive clause
- D. Noun clause
Correct answer: B
Rationale: The clause "as the sun dipped below the horizon" provides additional information about the main clause "We sat on the beach," making it a subordinate clause.
3. What are isotopes?
- A. Atoms of the same element with different numbers of protons.
- B. Atoms of the same element with different numbers of neutrons.
- C. Atoms of different elements with the same number of protons.
- D. Atoms of different elements with the same number of electrons.
Correct answer: B
Rationale: Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This means that isotopes have the same atomic number (Z) but different mass numbers (A). For example, carbon-12 (¹²C), carbon-13 (¹³C), and carbon-14 (¹â´C) are all isotopes of carbon. They all have six protons in their nuclei, but they have different numbers of neutrons: carbon-12 has six neutrons, carbon-13 has seven neutrons, and carbon-14 has eight neutrons.
4. A large geographic area characterized by similar climate, plants, and animals is called a:
- A. Population
- B. Community
- C. Biome
- D. Ecosystem
Correct answer: C
Rationale: Rationale: A) Population refers to a group of individuals of the same species living in a specific area. B) Community refers to all the populations of different species living and interacting in a particular area. C) Biome is a large geographic area characterized by similar climate, plants, and animals. Biomes are defined by factors such as temperature, precipitation, and vegetation types. D) Ecosystem refers to a community of living organisms interacting with each other and their physical environment. An ecosystem can be part of a biome.
5. How did life most likely arise on Earth?
- A. From simple organic molecules in a primordial soup
- B. By spontaneous generation from non-living matter
- C. Through the arrival of extraterrestrial life forms
- D. We still don't know for sure
Correct answer: A
Rationale: Rationale: The most widely accepted scientific theory for the origin of life on Earth is abiogenesis, which suggests that life arose from simple organic molecules in a primordial soup. This theory is supported by experiments such as the Miller-Urey experiment, which demonstrated that the basic building blocks of life could have formed under early Earth conditions. While there are other hypotheses and ongoing research in this field, the primordial soup theory is currently the most plausible explanation for the origin of life on Earth. The other options (B, C, and D) are not supported by scientific evidence or consensus.
6. What is the meaning of the idiom "to bite off more than one can chew"?
- A. To be overly confident
- B. To take on more than one can handle
- C. To be easily discouraged
- D. To be meticulous in planning
Correct answer: B
Rationale: The idiom warns against undertaking a task exceeding one's capabilities.
