What is the Atomic Mass a measure of?
Atomic Mass = Protons + Neutrons
What happens during S phase of the cell cycle?
DNA is replicated.
________ is when new memories make you forget old memories.
retroactive interference
What is avogadros number?
6.0 x 1023
What is the formula relating flow rate and linear speed of fluids? (HINT: also called the "continuity equation")
Q = v1A1 = v2A2
where A = cross-sectional area
Q = flow rate
v = velocity
Give the rate law for a reaction of the 1st order.
R = k[A]
What do kinases do?
Catalyze the transfer of a phosphate group (usually from ATP) to another molecule.
The principle of linguistic _______ holds that the structure of a language affects the ways in which its respective speakers conceptualize their world.
The principle of linguistic relativity holds that the structure of a language affects the ways in which its respective speakers conceptualize their world.
What is the formula for absolute pressure? (Hint: The absolute pressure is defined as the sum of all pressures at a certain point within a fluid.)
Pabsolute = P0 + ρgz
where P0 = Pressure at the surface of the fluid
ρ = density
z = depth of object (distance from surface)
What is the fundamental unit of charge on a proton or electron? e = ? (include units)
e = 1.6 x 10^-19 Coulombs (C)
Name the polyatomic ion:
ClO4-
Perchlorate
A fatty acid would have the general formula Rn—X, where X is what? (Hint: includes carbon, oxygen and hydrogen)
The fatty acid general formula would be:
Rn—CO2H
A higher p-value indicates what about the experimental differences?
*Higher* p-values indicate a higher probability of random chance, and therefore a *lower* probability that the observed difference is real (ie, due to experimental differences).
What is the formula used for Heat of Transformation/ Heat Transferred? (Hint: Used for phase changes)
Q = (m)(HT) where,
m = mass
Q = heat transferred during the phase change
HT (sometimes shown as HL) = Heat of Transformation
What are the conditions and formula for Boyle's Law? (Either version of the principle will be accepted)
Conditions: Moles (n) and Temperature are constant.
Formula:
PV = K (where K = constant) OR P1V1 = P2V2
Which of the following are common reducing agents? (pick as many as are correct)
B2H6, I2, H2SO4, CrO3, NAD+, NADH
Reducing agents get OXIDIZED, and oxidation is losing electrons. Therefore, reducing agents often contain metal ions or hydrides (H-).
Answers: B2H6, NADH
What do the hormones FSH and LH do for the male and female reproductive system?
Hint: FSH primarily influences gametes while LH primarily affects puberty
FSH: In females it stimulates the development of ovarian follicles.
In males it triggers spermatogenesis and stimulates Sertoli cells.
LH: In females it induces ovulation.
In males it causes interstitial cells to produce testosterone.
Which of Gestalts principles explains why we tend to see complete figures when part of the image is missing?
Gestalts principle of closure
What is the formula for critical speed of a fluid traveling through a tube/pipe?
Vc = (Nrη)/(ρD) where:
Nr = Reynolds number
η = viscosity
ρ = density
D = diameter of tube
What are the conditions and formula for Charles's Law? (BOTH versions of the principle are required)
Conditions: Moles (n) and pressure are constant.
Formula:
V/T = K (where K = constant) OR V1/T1 = V2/T2
Kinetic products are ________ in free energy compared to thermodynamic products and can form at ______ temperatures
Kinetic products are higher in free energy compared to thermodynamic products and can form at lower temperatures
Describe what happens in the cell during the 4 steps of Mitosis.
Prophase: DNA condenses, centrioles migrate to opposite poles and microtubules form. Nuclear envelope disappears.
Metaphase: Chromosomes line up at the metaphase plate.
Anaphase: Sister chromatids separate and move to opposite poles.
Telophase: Chromosomes decondense and nuclear membrane forms. Cytokinesis occurs.
What connects the Broca's area to the Wernicke's area?
The arcuate fasciculus connects the Broca's area to the Wernicke's area.
What is Bernoulli's Equation?
P1 + (1/2)(ρ1v12) + ρ1gh1=P2 +(1/2)(ρ2v22) + ρ2gh2
where P = absolute pressure of the fluid
ρ = density of the fluid
v = linear speed of fluid
h = height of the fluid above certain defined point
