Question 2 of 5
A group of students performed an experiment to test terminal velocity, which is the greatest speed obtained by a falling object. The students dropped different numbers of coffee filters and measured the resulting terminal velocity. Which of the following conclusions is supported by the data in the following data table?
Correct Answer: D
Rationale: The correct conclusion supported by the data is that heavier objects fall faster than lighter objects. Heavier objects experience a greater gravitational force, causing them to fall faster. This aligns with the concept of terminal velocity, which is the maximum speed a falling object can reach when the force of gravity is balanced by air resistance. Due to the stronger pull of gravity on heavier objects, they can overcome air resistance more effectively and reach terminal velocity faster compared to lighter objects.
Question 3 of 5
Which of the following blood vessels is affected by a myocardial infarction?
Correct Answer: A
Rationale: A myocardial infarction affects the coronary arteries, not the vena cava, pulmonary, or aorta. The coronary arteries supply blood to the heart muscle, and blockages in these arteries can result in a heart attack. The vena cava is a large vein that carries deoxygenated blood back to the heart, the pulmonary arteries carry deoxygenated blood from the heart to the lungs for oxygenation, and the aorta is the main artery that carries oxygenated blood from the heart to the rest of the body. These vessels are not typically associated with myocardial infarctions as they perform different functions within the circulatory system.
Question 4 of 5
Which of the following microorganisms lacks its own metabolic pathways and can only reproduce inside a host cell?
Correct Answer: B
Rationale: The correct answer is B: Viruses. Viruses are obligate intracellular parasites, lacking metabolic pathways and being dependent on a host cell for replication. Unlike bacteria, protozoa, or muscle cells, viruses utilize the host cell's resources and machinery to replicate their genetic material and produce new viral particles.
