Question 1 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.

Question 2 of 5

What is the recommended daily fluid intake for adults?

Correct Answer: B

Rationale: The recommended daily fluid intake for adults is typically around 2 liters, which is equivalent to about 8 cups or half a gallon. This amount can vary depending on factors such as age, gender, weight, activity level, and climate. Staying adequately hydrated is essential for overall health and helps maintain proper bodily functions, such as regulating body temperature, aiding digestion, and transporting nutrients and oxygen throughout the body. Drinking enough fluids also helps prevent dehydration, which can lead to symptoms like fatigue, headaches, and dizziness. Choice A, 1 liter, is insufficient and may not meet the body's hydration needs, while choices C and D, 3 liters and 4 liters, respectively, are excessive for most adults and could potentially lead to overhydration, which may have negative health consequences. It's important to note that individual fluid needs may vary, so it's always best to consult with a healthcare provider for personalized recommendations.

Question 3 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 4 of 5

Parkinson's disease is a neurodegenerative disorder affecting which neurotransmitter?

Correct Answer: A

Rationale: Parkinson's disease is primarily caused by the loss of dopamine-producing neurons in the brain. Dopamine is a neurotransmitter that plays a crucial role in coordinating movement. The reduction of dopamine levels leads to the characteristic motor symptoms of Parkinson's disease, such as tremors, rigidity, and bradykinesia. Choice B, acetylcholine, is involved in functions like muscle contraction and autonomic nervous system regulation but is not primarily affected in Parkinson's disease. Serotonin (Choice C) is involved in mood regulation and sleep, not the main neurotransmitter affected in Parkinson's disease. Glutamate (Choice D) is the major excitatory neurotransmitter in the central nervous system and is not primarily implicated in Parkinson's disease pathophysiology.

Question 5 of 5

What is the medical term for a urinary tract infection (UTI)?

Correct Answer: B

Rationale: The medical term specifically used to refer to a urinary tract infection (UTI) that affects the bladder is cystitis. Nephritis refers to inflammation of the kidneys, and urethritis refers to inflammation of the urethra. As such, cystitis is the correct term for a UTI, making choice B the right answer. Choices A, C, and D are incorrect because they refer to different conditions affecting the urinary system.
