1. Which of the following best defines the word circumvent?
- A. To go around
- B. To go under
- C. To come near
- D. To come through
Correct answer: A
Rationale: The correct answer is A: 'To go around.' Circumvent means to find a way around an obstacle or to avoid something by cleverness or deception. Choice B, 'To go under,' is incorrect as circumvent does not involve going under something. Choice C, 'To come near,' is incorrect as circumvent does not mean to approach or get close to something. Choice D, 'To come through,' is incorrect as circumvent does not involve passing through something.
2. Where in the cell are proteins modified, sorted, and packaged for transport?
- A. Ribosomes
- B. Golgi apparatus
- C. Endoplasmic reticulum (ER)
- D. Lysosomes
Correct answer: B
Rationale: The Golgi apparatus is the cellular organelle responsible for modifying, sorting, and packaging proteins for transport within the cell or for secretion outside the cell. Ribosomes are not involved in modifying, sorting, or packaging proteins; they are responsible for protein synthesis. The endoplasmic reticulum (ER) is primarily involved in protein synthesis and folding, rather than modification and packaging for transport. Lysosomes function in breaking down cellular waste rather than modifying, sorting, or packaging proteins for transport.
3. A soccer field is rectangular in shape and is 100 meters long and 75 meters wide. The hectare is a metric unit of area often used to measure larger areas. Given that 1 hectare = 10,000 square meters, which of the following represents the soccer field’s area in hectares?
- A. 0.75 hectares
- B. 7.5 hectares
- C. 7,500 hectares
- D. 75,000,000 hectares
Correct answer: A
Rationale: To find the area of the soccer field, multiply its length by its width: 100 meters × 75 meters = 7500 square meters. To convert this to hectares, divide by 10,000 (since 1 hectare = 10,000 square meters), resulting in 0.75 hectares. Therefore, the correct answer is A. Choices B, C, and D are incorrect because they do not correctly convert the area to hectares. B and C are off by a factor of 10, while D is off by a factor of 10,000.
4. What is the relationship between work and kinetic energy?
- A. Work is the cause of kinetic energy
- B. Kinetic energy is the result of work
- C. Work and kinetic energy are equivalent
- D. Work and kinetic energy are independent
Correct answer: A
Rationale: Work is defined as the transfer of energy that results in an object's displacement. When work is done on an object, it gains kinetic energy. This means that work is the cause of kinetic energy, as the energy transferred through work leads to the object's motion, which is represented by kinetic energy. Therefore, choice A is correct. Choice B is incorrect because kinetic energy is the result of work, not the other way around. Choice C is incorrect as work and kinetic energy are not equivalent but rather interconnected. Choice D is incorrect as work and kinetic energy are not independent; work leads to changes in kinetic energy.
5. What is the primary purpose of control rods within a nuclear reactor?
- A. Reflecting neutrons back into the core
- B. Absorbing excess neutrons to control criticality
- C. Moderating the velocity of neutrons
- D. All of the above
Correct answer: B
Rationale: The primary purpose of control rods in a nuclear reactor is to absorb excess neutrons to control criticality. When inserted into the reactor core, control rods absorb neutrons, reducing the number available for sustaining the fission chain reaction. This action allows operators to manage the reactor power levels and prevent overheating or runaway reactions. Reflecting neutrons back into the core and moderating neutron velocity are not the primary functions of control rods in a nuclear reactor. Choice A is incorrect because control rods do not reflect neutrons back into the core but absorb them. Choice C is incorrect as the moderation of neutron velocity is typically achieved by other materials like a moderator (e.g., water, graphite) rather than control rods. Choice D is incorrect as control rods do not reflect neutrons or moderate neutron velocity, making it an incorrect option.
