Question 1 of 5
What is the term for the inflammation of the airways in the lungs, often causing wheezing and difficulty breathing?
Correct Answer: C
Rationale: Asthma is a chronic respiratory condition characterized by inflammation of the airways in the lungs, leading to symptoms such as wheezing, shortness of breath, chest tightness, and coughing. Pneumonia is an infection in the lungs caused by bacteria, viruses, or fungi, leading to symptoms like fever, cough, and difficulty breathing. Emphysema is a type of chronic obstructive pulmonary disease (COPD) characterized by damage to the air sacs in the lungs, resulting in shortness of breath and a chronic cough. Pleurisy, on the other hand, is inflammation of the lining around the lungs, causing chest pain that worsens with breathing or coughing. Therefore, the correct term for the inflammation of the airways in the lungs with symptoms of wheezing and difficulty breathing is Asthma.
Question 2 of 5
What happens to the density of a gas when its temperature increases at constant pressure?
Correct Answer: B
Rationale: When the temperature of a gas increases at constant pressure, the average kinetic energy of the gas molecules increases. This leads to the gas molecules moving faster and spreading out more, which causes them to occupy a larger volume. As a result, the density of the gas decreases because the same number of gas molecules are now distributed over a larger space. Choice A is incorrect because as the gas molecules spread out, the density decreases. Choice C is incorrect because the increase in temperature leads to a decrease in density due to the increased volume occupied by the gas molecules. Choice D is incorrect because with the provided scenario of temperature increase at constant pressure, the effect on density can be determined.
Question 3 of 5
What is the name of the curved bone in the back that provides support and attachment for muscles?
Correct Answer: D
Rationale: The vertebral column, also known as the spine, is the curved bone in the back that provides support and attachment for muscles. It consists of individual vertebrae stacked on top of each other, forming a flexible and protective structure for the spinal cord. The sternum, scapula, and clavicle are bones in the chest and shoulder regions, not in the back where the vertebral column is located. Therefore, the correct answer is the vertebral column (Option D). Options A, B, and C are incorrect as they are bones situated in the chest and shoulder areas, not in the back where the vertebral column is found.
Question 4 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 5 of 5
What is the process by which a large, unstable nucleus splits into two smaller nuclei, releasing neutrons and energy?
Correct Answer: D
Rationale: Nuclear fission is the correct answer. It is the process in which a large, unstable nucleus splits into two smaller nuclei, releasing neutrons and energy. Alpha decay, beta decay, and gamma decay involve the emission of alpha particles, beta particles, and gamma rays, respectively. These decay processes do not result in the splitting of a nucleus like nuclear fission does.
