... [Show More] retina
Farsighted (hyperopia) - ANSWERSConverging lens; image is focused beyond the retina
Index - ANSWERSSpeed of air (Vair) / Speed of medium (Vmedium)
Ratio of h(image) to h(object) - ANSWERSf of image/ f of object
Ratio of O/I distance = Ratio of O/I height
Mass of O/mass of submerged - ANSWERSdensity 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 - ANSWERSThe 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 - ANSWERSv=f(lamda)
Unknown O = 31.6N
Apparent weight = 19.8N
specific gravity of sample? - ANSWERSUnknown O force / Liquid displaced force
32N / (32N-20N) = 32/12 = 8/3 = 2.66
Apoptosis - ANSWERSCytochrome C release from MT
Cell shrinkage and blebbing
Caspase activation
Specific activity of a protein - ANSWERSMeasure 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 - ANSWERS2 molecules of NADH (reducing agent)
Sociological concept of Medicalization - ANSWERSA 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 - ANSWERSan attribute that is devalued
Derived from symbolic interactionist perspective in sociology and calls attention to how certain individuals or groups face social disapproval. Often, the social disapproval is associated with a behavior, identity, or other attribute that is considered deviant by others
Looking-glass self - ANSWERSSelf concept as a product of social interaction, emerging out of the way an individuals perceives others to view him or her
More than the product of self-reflection
The way in which people see themselves is based on how they believe others perceive them during social interaction
Social epidemiology - ANSWERSThe social determinants of health and disease
Dramaturgical approach to social interaction - ANSWERSAn individual will modify his or her front stage self in response to the perceived audience
Dramaturgical approach - ANSWERSFront stage self
back stage self
Impression management
Communication
Validity - ANSWERSto the extent to which a measure reflects the phenomenon being studied
Role strain - ANSWERSStress experienced from contradictory demands of the same social role
Ex) physician
demand of extending life with interventions while accepting the reality of death
Ethnographic research - ANSWERSObserving social interactions in real social setting
Actor-observer bias - ANSWERSActor's tendency to explain his/her own behavior by situational factors whereas the observer tends to explain the actor's behavior by internal stable traits
Diathesis-stress model - ANSWERSIntegrate the influence of biological predispositions and the environment
Learned helplessness - ANSWERSUncontrollable exposer to an aversive stimulus results in learned helplessness, independent of the intensity of the punishment
Regular breathing and regular, slow brain waves - ANSWERSStage 3 - deep sleep stage
Humanistic perspective - ANSWERSExplain behavior through self-concept and incongruence
Neural plasticity - ANSWERSChanges in brain size as a function of environmental influences
Social facilitation - ANSWERSA participant is asked solve an easy puzzle in front of other participant
Encoding specificity effect - ANSWERSEnhanced memory when testing takes place under the same conditions as learning
Belief perseverence - ANSWERSThe tendency to hold on a set of beliefs in spite of being faced by evidence that proves otherwise
Hindsight bias - ANSWERSinclination, after an event has occurred, to see the event as having been predictable, despite there having been little or no objective basis for predicting it.
Long-term potentiation - ANSWERSThe consistent process of strengthening neural synapses according to various activation patterns. As a synapse strengthens, the signal transmission time becomes quicker.
For example: a mouse is placed in a maze, and in one of the corners is a piece of cheese. Assuming the mouse is successful, and finds the cheese, the mouse will more easily find the cheese (if put in the same place), next time he is placed in the maze.
CAT scan and MRI - ANSWERSTo study the structure of the brain
fMRI and PET scan - ANSWERSfMRI - detect brain activity
PET - detect brain activity using radioactive glucose tracers
Latent learning - ANSWERSA form of learning that occurs without any obvious reinforcement or punishment
Binocular depth cue - ANSWERSRetinal disparity - the space between the eyes that allows binocular vision to create depth perception.
Motion parallax - ANSWERSA depth cue that results from our motion. As we move, objects that are closer to us move farther across our field of view than do objects that are in the distance.
Good insulator; poor conductor - ANSWERSElectrons in the material cannot easily move from one atom to another
The valence electrons are tightly bound to their atoms, and it takes a great amount of energy to free them from their atomic energy levels
A volume of gas at higher Pressure (1 atm -> 500 atm) - ANSWERSSomewhat more than ideal gas volume because of the space occupied by the individual gas molecules
During titration, the pH at which a color change is observed depends on the: - ANSWERSpKa of indicator (Hin)
The indictor will change color over a specific pH range. The range at which the color change takes place depends on the point at which Hin is converted to In-, and this depends on the pKa of the indicator.
Which substance is more likely to be more soluble in HCl than NaOH?
A. AgCl
B. Pb(OH)2
C. CaF2
D. HI - ANSWERSAs the basic anion is consumed, the dissolution reaction is driven to the right by Le Chatelier's principle
Sperm movement from male testis to the fertilization in the female - ANSWERSEpididymis, vas deferens, urethra, vagina, cervix, uterus, Fallopian tube
Level of albumin at HIGH - ANSWERSAn influx of interstitial fluid into the bloodstream
Single spermatocyte with double chromosomal duplication before tetrad formation - ANSWERSNormal 1 spermatocyte - 4 haploid sperm
Abnormal duplication - 4 diploid sperm
Knee-jerk reflex - ANSWERSSimple monosynaptic stretch reflex
Germ cell layer of
endotherm
mesoderm
ectoderm - ANSWERSEctoderm - nervous system and epidermis (eye)
Endotherm - lining of the digestive tube and associated organs (lung)
Endotherm - blood cells, connective tissue (bones, muscles, and tendons), and several organs (kidney, heart, gonad)
Highest rate of endocytosis - ANSWERSA macrophage
Clear cells and tissue debris and foreign objects from the body by endocytosis (the process by which cells engulf extracellular materials)
Neurotransmitter - ANSWERSExocytosis
Glycolytic pat [Show Less]
