1. What is the process of converting DNA into a protein called?

Correct answer: B

Rationale: Translation is the correct answer. It is the process of converting the information in mRNA into a sequence of amino acids to form a protein. Transcription (Choice A) is the process of copying a segment of DNA into RNA. Replication (Choice C) is the process of making an identical copy of DNA. Mutation (Choice D) refers to a change in the DNA sequence that can lead to variations in proteins, but it is not the process of converting DNA into a protein.

2. How does an increase in surface area affect the force of friction between two surfaces?

Correct answer: A

Rationale: An increase in surface area typically increases the force of friction between two surfaces. This is because with a larger surface area in contact, there are more points of contact between the surfaces, leading to a greater frictional force resisting motion. As a result, the correct answer is that an increase in surface area increases the force of friction between two surfaces. Choice B is incorrect because a greater surface area increases the frictional force. Choice C is incorrect because an increase in surface area results in more contact points and greater friction. Choice D is incorrect as the relationship between surface area and friction is predictable - an increase in surface area generally leads to an increase in frictional force.

3. Which respiratory structure is responsible for vocalization and sound production?

Correct answer: B

Rationale: The correct answer is B: Larynx. The larynx, also known as the voice box, is the respiratory structure responsible for vocalization and sound production. It contains the vocal cords, which vibrate as air passes through, producing sound. The trachea (A) connects the larynx to the bronchi. While the trachea serves as the windpipe, it is not directly involved in sound production. Bronchi (C) are airway passages that branch off from the trachea and lead to the lungs, but they are not responsible for vocalization. Alveoli (D) are tiny air sacs in the lungs where gas exchange occurs, but they are not involved in sound production.

4. Which part of the digestive system is responsible for absorbing nutrients?

Correct answer: C

Rationale: The small intestine is the correct answer because it is the primary site for nutrient absorption in the digestive system. It contains specialized structures such as villi and microvilli that maximize the absorption of nutrients from digested food. The esophagus is responsible for transporting food from the mouth to the stomach; the stomach primarily aids in digestion by secreting enzymes and acids; and the large intestine mainly absorbs water and electrolytes from the remaining indigestible food matter. Therefore, the small intestine plays a crucial role in absorbing essential nutrients for the body's functions, making it the correct choice in this context.

5. According to the wave theory of light, the bright fringes observed in a double-slit experiment correspond to:

Correct answer: A

Rationale: In a double-slit experiment based on the wave theory of light, the bright fringes are the result of constructive interference. Constructive interference occurs when light waves from the two slits arrive at a point in phase, reinforcing each other and creating a bright fringe. This reinforcement leads to the constructive addition of the wave amplitudes, resulting in a bright spot on the screen. Destructive interference, which would result in dark fringes, occurs when waves are out of phase and cancel each other out. Increased diffraction and total internal reflection are not related to the formation of bright fringes in a double-slit experiment. Therefore, the correct answer is constructive interference.
