1. The important decision will be made tomorrow. Which word is the comparative form of the adjective "important"?
- A. important
- B. importantly
- C. more important
- D. most important
Correct answer: C
Rationale: The comparative form of an adjective compares two things.
2. The human body's command center, integrating sensory information and coordinating movement and vital functions, is the:
- A. Lungs
- B. Brain
- C. Kidneys
- D. Stomach
Correct answer: B
Rationale: The correct answer is B: Brain. The brain serves as the command center of the human body, receiving sensory information from various parts of the body and coordinating responses. It is responsible for controlling movement, regulating vital functions such as breathing and heart rate, and processing thoughts and emotions. The lungs (A), kidneys (C), and stomach (D) each have specific functions within the body, but they do not serve as the central command center like the brain does. Therefore, the brain is the correct answer to this question.
3. Which of the following is an example of stabilizing selection?
- A. Selection that favors extreme traits in a population
- B. Selection that removes individuals with extreme traits
- C. Selection that maintains the current average trait in a population
- D. Selection that favors one specific trait over all others
Correct answer: C
Rationale: Rationale: - Stabilizing selection is a type of natural selection that favors the intermediate variants in a population, while selecting against the extreme traits. This results in the maintenance of the current average trait in the population. - Option A is incorrect because stabilizing selection does not favor extreme traits; instead, it favors the average trait. - Option B is incorrect because stabilizing selection does not remove individuals with extreme traits; it acts against extreme traits by favoring the intermediate variants. - Option D is incorrect because stabilizing selection does not favor one specific trait over all others; it favors the average trait by selecting against extreme traits.
4. Cherenkov radiation is a characteristic phenomenon associated with:
- A. Alpha particle emission
- B. Beta particle emission
- C. Gamma ray emission
- D. Charged particles exceeding the speed of light in a medium
Correct answer: C
Rationale: Cherenkov radiation is a phenomenon associated with charged particles exceeding the speed of light in a medium. When a charged particle travels faster than the speed of light in that medium, it emits a characteristic blue glow known as Cherenkov radiation. This occurs due to the disruption of the electromagnetic field in the medium by the high-speed particle. Options A, B, and C are not correct as they do not directly relate to the specific condition required for Cherenkov radiation to be produced. Therefore, option D, 'Charged particles exceeding the speed of light in a medium,' is the correct answer.
5. A symbiotic relationship where one organism benefits and the other is not harmed is called:
- A. Mutualism
- B. Commensalism
- C. Parasitism
- D. Predation
Correct answer: B
Rationale: Rationale: A) Mutualism: In mutualism, both organisms involved benefit from the relationship. B) Commensalism: In commensalism, one organism benefits while the other is neither helped nor harmed. This is the relationship described in the question. C) Parasitism: In parasitism, one organism benefits at the expense of the other organism, which is harmed. D) Predation: In predation, one organism (predator) kills and consumes another organism (prey) for food.
6. Which of the following organs is responsible for the mechanical breakdown of food into smaller pieces?
- A. Esophagus
- B. Stomach
- C. Small intestine
- D. Mouth
Correct answer: D
Rationale: The correct answer is D: Mouth. The mouth is responsible for the mechanical breakdown of food into smaller pieces through the process of chewing. The teeth in the mouth help to grind and crush food into smaller particles, making it easier for digestion to occur. The esophagus is a muscular tube that transports food to the stomach but does not contribute to mechanical breakdown. The stomach is responsible for further breaking down food using acid and enzymes, while the small intestine is mainly involved in the absorption of nutrients. Therefore, the mouth plays a crucial role in the initial mechanical digestion of food.
