1. Which of the following lobes of the brain is responsible for processing auditory sounds?

Correct answer: D

Rationale: The correct answer is D: Temporal. The temporal lobe of the brain is responsible for processing auditory sounds. It is also involved in memory and language functions. Choice A, Frontal lobe, is primarily associated with functions such as decision-making, problem-solving, and planning. Choice B, Occipital lobe, is responsible for processing visual information. Choice C, Parietal lobe, is involved in processing sensory information like touch, temperature, and pressure. Therefore, the temporal lobe is the specific lobe responsible for processing auditory information, making it the correct answer.

2. Which organ is responsible for detoxifying harmful substances in the body?

Correct answer: B

Rationale: The correct answer is the Liver. The liver is the organ responsible for detoxifying harmful substances in the body. It accomplishes this by metabolizing drugs and filtering blood. The liver plays a crucial role in maintaining overall health by processing and eliminating toxins. Choices A, C, and D are incorrect. The kidneys primarily filter blood to remove waste and excess substances, the heart is responsible for pumping blood throughout the body, and the pancreas aids in digestion and regulating blood sugar levels, but none of these organs are primarily responsible for detoxification.

3. Which type of bond involves the complete transfer of electrons between atoms?

Correct answer: B

Rationale: The correct answer is B, Ionic bond. Ionic bond involves the complete transfer of electrons from one atom to another, resulting in the formation of cations and anions. This transfer leads to the creation of strong electrostatic attraction between the oppositely charged ions. Covalent bonds, on the other hand, involve the sharing of electrons between atoms to achieve stability. Metallic bonds are formed in metals, where a sea of delocalized electrons surrounds positively charged metal ions, contributing to the metal's properties. Hydrogen bonds are intermolecular forces that occur between a hydrogen atom and a highly electronegative atom like oxygen or nitrogen, not involving the complete transfer of electrons.

4. Which of the following statements regarding heart valves is correct?

Correct answer: D

Rationale: All of the statements are correct regarding heart valves. Choice A is accurate as the atrioventricular valves indeed lie between the atria and the ventricles. Choice B correctly identifies the location of the pulmonary semilunar valve. Choice C is true as the atrioventricular valves do prevent backflow into the atria during ventricular contraction. Therefore, selecting 'All of the above' as the correct answer is appropriate as all statements are accurate.

5. Which property of a wave is measured in Hertz (Hz)?

Correct answer: D

Rationale: Frequency is the property of a wave that is measured in Hertz (Hz). It represents the number of complete cycles of the wave that occur in one second. Amplitude refers to the height of the wave, wavelength is the distance between two consecutive points on a wave that are in phase, and speed is the rate at which the wave travels through a medium. Therefore, the correct answer is frequency as it directly corresponds to the unit Hertz (Hz) used to measure the number of wave cycles per second.
