Deviance is a situation in which an individual’s behavior violates social norms and induces a negative reaction.
BATS Drink Blood pnemonic for sleep stages
B: Beta -> wakefulness A: Alpha -> drowsy bitch T: Theta -> stage 1 and 2 S: Sleep spindles and K complexes -> stage 2 Drink: Delta -> stage 3/4 Blood: Beta -> REM

Con: Both dependent and Independent
Stage 2 of population growth
Death rates decline
Birth rates remain high
-Rapidly growing population
-These changes are due to medical and sanitation devices
Stage 3 of population growth
Mortality rates are low, birthrates start to decline
-Population stabilizes
Stage 4 of population growth
Birth and death rates are both low and constant
-Consistent with stable or slowly declining population

Posttraumatic stress disorder TRAUMA T: Traumatic event R: Re-experience A: Avoidance U: Unable to function M: Month or more of symptoms A: Arousal increased
Where is DA produced in the mesolimbic pathway
VTA
Ventral tegmental area
Roles of serotonin
Serotonin is involved in the regulation of a variety of psychological states and body functions, such as mood, appetite, sleep, and memory
Construct validity
whether a test measures what it is designed to measure
Face validity
perception by other experts of whether the test is relevant to its stated goals

At least 2 weeks
How long can major depressive episodes last
1-2 months
What is social diffusion
a process being transmitted across groups
What is social transmission
when ideas and behaviors are transmitted throughout a single group.
Which NTs are monoamines
adrenaline (epinephrine), norepinephrine, dopamine,
serotonin, and melatonin
Can serotonin cross the blood brain barrier?
No
Can amino acids cross the blood brain barrier
yes

The economic conditions
Allport theory
Cardinal, central, secondary traits
Jung theory
Archetypes
Cattell theory of personality
We have 16 personality traits
What is dysthymia
a more subtle form of depression. This mood disorder may cause feelings of sadness and perhaps pessimism
What is the equation for rate of effusion
sqrt(3RT/MM)
MM=molar mass
R=ideal gas constant
T=temp
What is the equation comparing rates of effusion
rate1/rate2 = (sqrt(3RT1/MM1))/(sqrt(3RT1/MM1))
Myopia means?
Nearsightedness
-Light rays converge too early
How to correct myopia
Use concave/diverging lens
-LIght rays will be properly focused on retina
What is hyperopia
Farsightedness
-Converges behind the retina
How to correct hyperopia
Use converging lens to focus it closer and onto the retina
Isolated system def
Exchange neither matter nor energy with the environment.
Closed system def
Can exchange energy but not matter with the environment.
Open system def
Can exchange BOTH energy and matter with the environment.
what is entropy maximized with respect to equilibrium
When deltaG=0
-No work can be done
When do gases behave most ideally
Under high temps and low pressure
What are standard conditions
25 degC or 298K
1 Atm or 1x10^5 Pa
Pressure conversions starting with 1 atm
1 atm = 760 mmHg = 760 torr = 1x10^5 Pa
What type of agent is LAH
Strong reducing agent
What is the only stereoselective reagent
diethyl tartrate
Max kinetic energy of a photon equation
Etotal - Ework function
Noncompetitive inhibition def
Vmax dec, Km unchanged
-Inhibitor binds to ES complex or active site
Uncompetitive inhibition def
Inhibitor only binds to ES complex
-Vmax and Km both dec
What are the unit conversion of an ampere
C/s
Watt SI units
1 J/S = kg*m^2/s^3
Newton SI units conversion
1N = 1kg/ms^2
Joule SI units conversion
1 J = 1 Nm = 1 kgm^2/s^2
Hz SI units conversion
1 Hz = 1/sec
Ampere SI units conversion
1 amp = 1C/s
What TCA cycle intermediates are used in Gluconeogenesis
Malate and OAA
Where is the highest concentration of phosphorus found
Nucleus
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.
Somatostatin works antagonistically against which hormone?
CCK
What type of hormone is CCK
Peptide hormone
SNOW DROP
S = southern blotting N = northern blotting W = western blotting D = DNA R = RNA P = proteins
What is CCK secreted by
Pancreas
PTH role
Lowers blood Ca levels
- Inc osteoclast activity
- Inc Ca absorption in intestines
- Inc Ca absorption in kidneys
Calcitonin Role
CalcitonIN -> Inc Ca blood levels
- Inc osteoblast activity
- Dec Ca absorption in intestines and kidneys
Stages of an action potential
- Cell crosses threshold voltage and is depolarized when sufficient amounts of Na+ enter cell
- Repolarization occurs as K+ cells leave the cell
- Refractory period occurs where K+ diffuses back into cells and cell reaches returns to potential
