Question 1 of 5
Which part of the brain is responsible for processing vision?
Correct Answer: A
Rationale: The occipital lobe is the part of the brain responsible for processing visual information. Located at the back of the brain, the occipital lobe contains the primary visual cortex, which plays a crucial role in interpreting visual stimuli received from the eyes. The frontal lobe is primarily involved in higher cognitive functions, decision-making, and motor control, not vision processing. The temporal lobe is responsible for auditory processing, memory, and emotion, not vision. The parietal lobe is involved in sensory integration, spatial awareness, and perception of stimuli, but not specifically for visual processing.
Question 2 of 5
What property of a wave determines its pitch in sound waves?
Correct Answer: B
Rationale: The pitch of a sound wave is determined by its frequency. Frequency is the number of cycles of a wave that occur in a unit of time, usually measured in hertz (Hz). Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches. Amplitude refers to the height of a wave and is related to the loudness of the sound. Wavelength is the distance between two consecutive points in a wave that are in phase, and speed is the rate at which a wave travels through a medium. Therefore, the correct answer is frequency as it directly correlates with the pitch of a sound wave.
Question 3 of 5
What is the process of converting light energy into chemical energy called?
Correct Answer: C
Rationale: - Respiration (Option A) is the process by which cells break down glucose to release energy. - Fermentation (Option B) is an anaerobic process that also involves the breakdown of glucose to release energy. - Hydrolysis (Option D) is a chemical process that involves the breakdown of molecules by adding water. Photosynthesis (Option C) is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. This process is essential for the survival of plants and ultimately sustains life on Earth by providing oxygen for other organisms to breathe and serving as a source of energy in the food chain.
Question 4 of 5
What is the difference between a phylum and a class?
Correct Answer: A
Rationale: In biological classification, a phylum is a higher taxonomic rank than a class. A phylum is a broader category that encompasses multiple classes within it. It represents a group of organisms sharing a common body plan or evolutionary history. On the other hand, a class is a more specific category within a phylum that includes organisms with similar characteristics. Therefore, phyla are broader and more general compared to classes. Choice B is incorrect because classes are more specific categories within phyla. Choice C is incorrect as phyla and classes are distinct hierarchical levels in taxonomy. Choice D is incorrect because phyla and classes are not restricted to specific types of organisms; they can apply to various organisms across the biological kingdom.
Question 5 of 5
An object is thrown at an angle. Which of the following forces acts HORIZONTALLY on the object during its flight?
Correct Answer: C
Rationale: During the flight of the object, the only force that acts horizontally on the object is air resistance. Air resistance opposes the motion of the object through the air and acts in the direction opposite to the object's velocity. Gravitational force acts vertically downward, influencing the object's weight and vertical motion. The normal force from the ground acts perpendicular to the ground to support the object's weight. The force of throwing initially imparts velocity to the object at an angle, but it does not act horizontally throughout the flight.
