AAMC Test 2 Flashcards
Venturi effect
- oxygen pressure is the sum of the static pressure P and the oxygen flow pressure rv^2/2
- air will enter the mask because the static pressure of the air is larger than the static pressure of the oxygen in the flow.
what gives the best estimate of a vapor pressure
- boiling point
role of a catalyst
- increase the rate of a chemical reaction
- amount of product formed per time
coordinate covalent
- the lewis acid-base interaction between a metal cation and an electron pair
secondary structures represented by
- repeated patterns of hydrogen bonds between backbone amide protons and carbonyl oxygen atoms
diverging lenses
- negative focal length
- virtual and reduced images
egg and sperm are most similar in respect to
- genome size
derived from mesoderm
- heart
- kidney
- skeletal muscle
which cells are highly proliferative
- epithelial cells that line the digestive tract.
purines are how many rings?
- 2
pyrimidines are how many rings?
- 1
secretory protein secretion and folding occurs where
- rough ER
ubiquitination
- targets a protein for degradation by a proteosome
transmembrane domains are most likely to be
- hydrophobic and nonpolar
posttranslational modifications of proteins are best analyzed by
- Western blotting
blood from the small intestine goes where?
- the liver to remove toxins
internalization of viral particles through endocytosis is mediated by
- endosomes
the addition of one nucleotide to an open reading frame
- frameshift mutated and an aberrant carboxy-terminal domain
microtubules originate from
- centrosomes
dependency ratio
- the number of economically dependent members of the population to the number of economically productive members
linguistic relativity hypothesis
- suggests that human cognition is affected by language
selectively forgetting distracting elements of life
- dissociative disorder
what drug has the lowest risk of dependence
- hallucinogens
how do individuals respond in groups?
- they are often less critical and less creative
what part of the brain plays a role in intense emotional reactions?
- amygdala
right hemisphere of the brain more linked with
- visuospatial skills
- music perception
- emotion processing
the presence of alpha-beta plaques and neurofibrillary tangles will not allow for what?
- increased connection between neurons in the brain
Hawthorne effect
- describes changes in research participants as a result of their awareness that they are being observed
