Allport theory
Cardinal, central, secondary traits
26
Jung theory
Archetypes
27
Cattell theory of personality
We have 16 personality traits
28
What is dysthymia
a more subtle form of depression. This mood disorder may cause feelings of sadness and perhaps pessimism
29
What is the equation for rate of effusion
sqrt(3RT/MM) MM=molar mass R=ideal gas constant T=temp
30
What is the equation comparing rates of effusion
rate1/rate2 = (sqrt(3RT1/MM1))/(sqrt(3RT1/MM1))
31
Myopia means?
Nearsightedness | -Light rays converge too early
32
How to correct myopia
Use concave/diverging lens | -LIght rays will be properly focused on retina
33
What is hyperopia
Farsightedness | -Converges behind the retina
34
How to correct hyperopia
Use converging lens to focus it closer and onto the retina
35
Isolated system def
Exchange neither matter nor energy with the environment.
36
Closed system def
Can exchange energy but not matter with the environment.
37
Open system def
Can exchange BOTH energy and matter with the environment.
38
what is entropy maximized with respect to equilibrium
When deltaG=0 | -No work can be done
39
When do gases behave most ideally
Under high temps and low pressure
40
What are standard conditions
25 degC or 298K | 1 Atm or 1x10^5 Pa
41
Pressure conversions starting with 1 atm
1 atm = 760 mmHg = 760 torr = 1x10^5 Pa
42
What type of agent is LAH
Strong reducing agent
43
What is the only stereoselective reagent
diethyl tartrate
44
Max kinetic energy of a photon equation
Etotal - Ework function
45
Noncompetitive inhibition def
Vmax dec, Km unchanged | -Inhibitor binds to ES complex or active site
46
Uncompetitive inhibition def
Inhibitor only binds to ES complex | -Vmax and Km both dec
47
What are the unit conversion of an ampere
C/s
48
Watt SI units
1 J/S = kg*m^2/s^3
49
Newton SI units conversion
1N = 1kg/ms^2
50
Joule SI units conversion
1 J = 1 N*m = 1 kg*m^2/s^2
51
Hz SI units conversion
1 Hz = 1/sec
52
Ampere SI units conversion
1 amp = 1C/s
53
What TCA cycle intermediates are used in Gluconeogenesis
Malate and OAA
54
Where is the highest concentration of phosphorus found
Nucleus
55
Function of CCK
aid a series of processes involved in digestion - stimulating pancreatic acinar cells to release digestive enzymes, stimulating feelings of satiety (fullness) to suppress hunger, inhibiting stomach emptying, lowering gastric acid secretion.
56
Somatostatin works antagonistically against which hormone?
CCK
57
What type of hormone is CCK
Peptide hormone
58
SNOW DROP
``` S = southern blotting N = northern blotting W = western blotting D = DNA R = RNA P = proteins ```
59
What is CCK secreted by
Pancreas
60
PTH role
Lowers blood Ca levels - Inc osteoclast activity - Inc Ca absorption in intestines - Inc Ca absorption in kidneys
61
Calcitonin Role
CalcitonIN -> Inc Ca blood levels - Inc osteoblast activity - Dec Ca absorption in intestines and kidneys
62
Stages of an action potential
1. Cell crosses threshold voltage and is depolarized when sufficient amounts of Na+ enter cell 2. Repolarization occurs as K+ cells leave the cell 3. Refractory period occurs where K+ diffuses back into cells and cell reaches returns to potential
63
Mesoderm components
Moveoderm | Muscoskeleton,circulatorysystem,gonads,adrenalcortex.
64
Endoderm components
Indoderm | GItract,respiratorytract,bronchi,bladder,stomach.
