0 degrees F = how many Kelvin?
273 K
In Reverse-phase Chromatography, the Stationary phase is: Polar or non-polar?
non-polar
Note: In REGULAR TLC or paper chromatography, the stationary phase is polar.
The GI tract, respiratory tract, bronchi, bladder, and stomach are all formed in early development from which 1 of the 3 germ layers?
Endoderm
Of the two, which is role strain?
#1 When there are competing expectations for two or more roles, which creates tension.
OR
#2 When there are competing expectations within a single role, which creates tension.
#2
What is the formula for specific gravity?
S.G. = (DensityObject)/(DensityWater)
Convert 1 atm = torr/mmHg (HINT: torr = mmHg)
1 atm = 760 torr = 760 mmHg = 1.01 x 105 Pascals
In ideal gas conditions, quadrupling the Pressure of a gas would do what to the Volume of the gas?
Using the formula PV = nRT,
Multiplying P by 4 would mean V would be divided by 4.
P = x4, then V = 1/4
An increase in GnRH from the hypothalamus will likely cause which other two hormones to increase?
Increased GnRH --> Increased LH & FSH
Touch, pressure, temp, pain, and spatial processing and all controlled by which lobe of the cerebral cortex?
Parietal lobe
What is the fundamental unit of charge on a proton or electron? e = ? (include units)
e = 1.6 x 10^-19 Coulombs (C)
The properties of resistors depend on which of the following (pick any/all that apply):
-Resistivity
-Temperature
-Cross-sectional area
-Length
All are correct
What is the approximate bond angle of a Trigonal Pyramidal molecule?
< 109.5 degrees
Directions: Chose increase or decrease for each
Aldosterone causes a(n) _______ in both Na+ and H2O levels in the blood, which would result in a(n) _______ in blood volume.
Aldosterone *increases* Na+/H2O reabsorption into the bloodstream which results in an *increase* in blood volume.
What is Somatic Symptom Disorder? (Be specific)
When an individual expresses extreme concern over physical symptom(s). This concern is beyond a normal amount.
What is the formula for finding the Energy of a Photon?
E = hf
where h = Planck's constant
f = frequency
(Other formula also accepted)
What is the formula for magnitude of a uniform electric field?
E = V/d
where v = voltage difference (potential difference) between plates
d = distance between plates
Directions: Describe what happens when electrons jump to a higher shell in terms of:
1) Absorb or emit light?
2) Lower or higher potential?
3) Excited state or not?
4) Distance increases or decreases from the nucleus?
MNEMONIC: When electrons jump to a higher shell, think of AHED (Electrons jump higher to get AHED).
A - absorb light
H - higher potential
E - Excited state
D - Distance increases from the nucleus
What are the 3 amino acids that are able to get phosphorylated?
Serine, Threonine and Tyrosine (all contain -OH)
The vestibulo-ocular reflex does what?
Keeps the eyes fixed on a point as the head rotates.
What is the formula that you would use if you were asked to find the Capacitance of parallel plates and given the dimensions of the plates?
Where E0 = relative permativity
A = area of the plate
d = distance between the plates
Relationship between sound intensity and decibels:
For each 10-fold increase in sound intensity, how many decibels will the loudness increase by?
For each 10-fold increase in sound intensity, decibels will increase by 10dB.
ex. 10 to 100 (10-fold increase) would result in an increase by 10dB.
What are the conditions and formula for Avogadro's Principle? (Any version of the principle will be accepted)
Conditions: Constant pressure and Temperature
Formula:
n/v = K (where K = constant) OR n1v1 = n2v2

What is Poiseuille's Law? (Hint: this formula determines the rate of laminar flow)
Q = (πr4ΔP)/(8ηL)
where,
P = pressure
η = viscosity of the fluid
L = length of pipe/tube
