MCAT AAMC flashcard question with complete solution 2023Pressure (fluid) - correct answer pgh density x g x change in height Nearsighted (myopic) - correct answer Diverging lens; image is focused in front of retina Farsighted (hyperopia) - correct answer Converging lens; image is focused beyond the retina Index - correct answer Speed of air (Vair) / Speed of medium (Vmedium) Ratio of h(image) to h(object) - correct answer f of image/ f of object Ratio of O/I distance = Ratio of O/I height Mass of O/mass of submerged - correct answer density of O/ density of fluid Mass of O = 15, Mass of fluid loss = 5 15/5 = 3 = ratio of density of O/density of fluid density of fluid = 0.7 -> density of O = 0.7 x 3 = 2.1 Hydrostatic pressure - correct answer The pressure at the bottom of a tube of height h filled with liquid of density = pgh due to the weight of the liquid. Speed of a WAVE - correct answer v=f(lamda) Unknown O = 31.6N Apparent weight = 19.8N specific gravity of sample? - correct answer Unknown O force / Liquid displaced force 32N / (32N-20N) = 32/12 = 8/3 = 2.66 Apoptosis - correct answer Cytochrome C release from MT Cell shrinkage and blebbing Caspase activation Specific activity of a protein - correct answer Measure of the enzyme units per mg of total protein in a solution Provides a measure of the purity of an enzymatic mixture Disruption of 2 S-S bond - correct answer 2 molecules of NADH (reducing agent) Sociological concept of Medicalization - correct answer A problem becomes described in medical terminology and treated by medical professions Behavior problem (alcoholism) becomes described and treated as a medical condition when it was not previously conceived in that way Social stigma - correct answer an attribute that is devalued Derived from symbolic interactionist perspective in sociology and calls attention to how certain individuals or groups face social disapproval.
