1. Which of the following is an example of a zoonotic disease?

• A. The common cold
• B. Influenza (the flu)
• C. Malaria
• D. HIV/AIDS

Correct answer: B

Rationale: A zoonotic disease is a disease that can be transmitted from animals to humans. Influenza is an example of a zoonotic disease as it can be transmitted from animals such as birds and pigs to humans. The common cold (option A) is caused by human rhinoviruses and is not considered a zoonotic disease. Malaria (option C) is transmitted through the bite of infected mosquitoes and is not considered a zoonotic disease. HIV/AIDS (option D) is caused by the human immunodeficiency virus and is not considered a zoonotic disease.

2. Which of the following is NOT a mechanism of evolution?

• A. Natural selection
• B. Genetic drift
• C. Lamarckism
• D. Mutation

Correct answer: C

Rationale: A) Natural selection is a mechanism of evolution where individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to the next generation. B) Genetic drift is a mechanism of evolution that occurs due to random changes in allele frequencies in a population. C) Lamarckism, also known as the inheritance of acquired characteristics, is a discredited theory that suggests organisms can pass on traits acquired during their lifetime to their offspring. This mechanism has been largely rejected by the scientific community. D) Mutation is a mechanism of evolution that introduces new genetic variation into a population, which can lead to the emergence of new traits and adaptations over time.

3. What is the responsibility of the somatic nervous system?

• A. Breathing
• B. Thought
• C. Movement
• D. Fear

Correct answer: C

Rationale: The somatic nervous system is responsible for controlling voluntary movements of skeletal muscles. This system communicates sensory information and controls voluntary movements, such as walking or reaching for objects. Breathing is primarily regulated by the autonomic nervous system, which functions involuntarily. Thought processes involve complex interactions between various regions of the brain and are not directly controlled by the somatic nervous system. Fear is an emotional response that involves the limbic system of the brain and the autonomic nervous system, not the somatic nervous system.

4. Which of the following statements is NOT true of most metals?

• A. Most of them are good conductors of heat.
• B. Most of them are gases at room temperature.
• C. Most of them are ductile.
• D. They make up the majority of elements on the periodic table.

Correct answer: B

Rationale: The correct answer is B because most metals are not gases at room temperature; they are usually solid and good conductors of heat. Metals are generally known for being good conductors of heat, ductile, and making up the majority of elements on the periodic table. Choice A is correct as metals, in general, are good conductors of heat. Choice C is also correct as most metals exhibit ductility. Choice D is correct as metals constitute the majority of elements found on the periodic table.

5. Which of the following are properties of a liquid?

• A. High atomic attraction
• B. Fixed volume
• C. Low pressure
• D. Takes shape of container

Correct answer: D

Rationale: The correct answer is D: 'Takes shape of container.' Liquids exhibit the property of taking the shape of their container while maintaining a fixed volume. This is due to the ability of liquid particles to flow and move freely within the container. Choices A, B, and C are incorrect. Choice A, 'High atomic attraction,' is not a general property of liquids as the level of attraction between liquid particles can vary. Choice B, 'Fixed volume,' is partially correct as liquids do have a fixed volume, but they do not have a fixed shape. Choice C, 'Low pressure,' is not a defining property of liquids.
