Q

relationship between altruistic behavior and inclusive fitness

A

inclusive fitness is used to explain altruistic behavior

25
Q

fundamental attribution error

A

attributing a participant’s behavior to an internal factor (emotional state/anger issues) instead of considering external factors (they were having a bad day, the PDA broke 15 times before, etc.) which may be influencing his response

26
Q

schziophrenia

A

typically though of as an excess of dopamine levels particularly in the frontal lobes

27
Q

dramaturgical approach

A

considers individuals as actors on a drama stage

-individuals’ performances are affected by time, place, circumstance, race, and by the actors themselves

28
Q

somatoform disorder

A

pain without any discernable physical source

29
Q

assimilation example

A

a man was born in england and grew up eating meat pies and drinking Earl Grey tea all of his life. After moving to Georgia, he began losing his British accent and acquired a taste for fried foods and southern sweet tea

30
Q

social constructionsim

A

how groups of people come to ascribe meaning or value to objects or concepts

ex: assessing the importance of a new technology to a group of people

31
Q

psychoanalytic theory

A

personality is shaped by a person’s unconscious thoughts, feelings and past memories

32
Q

humanistic theory

A

focuses on the conscious

and says people are inherently good focuses on healthy personality development and humans are seen as inherently good

33
Q

biological theory

A

important components of personality are inherited or determine in part by our genes

34
Q

behaviorist theory

A

personality is the result of learned behavior patterns based on a person’s environment

35
Q

Broca’s Aphasia

A

inability to produce speech

36
Q

Wernicke’s aphasia

A

condition in which speech comprehension is compromised

37
Q

conduction aphasia

A

inability to repeat what they hear

38
Q

anomic aphasia

A

inability of a person to produce the correct words for a topic about which they’d like to speak

39
Q

conduction

A

heat transfer by direct contact

requires things to touch

40
Q

convection

A

heat transfer by flowing current

need the physical flow of matter

41
Q

radiation

A

heat transfer by electromagnetic radiation

does not need the physical flow of matter, can occur through a vaccum

42
Q

what does pKa measure?

A

how much a molecule wants to hold on to its protons

a pKa value for a weak acid like carbonic acid is always positive

43
Q

if the pKa is getting smaller, what does that mean for your Ka

A

gets larger, which indicates that there is more dissociation at higher temperature

44
Q

delta H

A

enthalphy

if delta H is positive, then it is endothermic and reaction must require heat

45
Q

micelles

A

assit in the digestion of fats by emulsifying them so they can be absorbed from the small intestine

46
Q

what is so important of micelles is that they

A

have a hydrophobic core and a hydrophilic exterior to assist the absorption of fat

47
Q

covlanet bond

A

formed b/w atoms that have similar electronegativities

48
Q

non polar covalent bond

A

formed between same atoms or atoms with very similar electronegativities
-different in electronegativity b/w bonded atoms is less than .5

49
Q

polar covalent bond

A

formed when atoms of slightly different electronegativities share electrons
-difference is between 0.5-1.9

ex: HCl, H2O, HF

50
Q

meatllic bond

A

occurs between atoms of metals, in which the valence electrons are free to move through the lattic

51
Q

the intramolecular forces from strongest to weakest

A

metallic
ionic
polar covalent
nonpolar covalent

52
Q

which are stronger: intramolecular forces or intermolecular forces?

A

intramolecular forces

-intermolecular forces are important because they determine the physical properties of molecules

53
Q

dipole-dipole interactions

A

forces occur when the partially positively charge part of a molecule interacts with the partially negatively charged part of the neighboring molecule

ex: HCl

54
Q

what is the strongest intermolecular force of attraction?

A

dipole-dipole interactions

55
Q

hydrogen bonding

A

hydrogen atom bonded to either an oxygen, nitrogen, or fluorine atom

56
Q

London dispersion forces

A

exist between all types of molecules
the more electrons a molecule has, the stronger the London dispersion forces are
-breaking of london dispersion forces doesn’t require that much energy

57
Q

what is the relationship between wavelength, frequency, and energy

A

energy is proportional to frequency
frequency is inversely proportional to wavelength
energy is inversely proportional to wavelength

58
Q

what is the energy of long wavelength photons

A

long wavelength, low energy
