False
True
undefined
Which statement about natural selection is correct?
It creates new alleles to match environmental needs
It acts on phenotypic variation that is heritable
It operates only in large populations
It aims to produce perfect organisms
undefined
For the reversible reaction N2 + 3H2 <-> 2NH3, decreasing volume at constant temperature will favor which side?
Products, because the reaction is exothermic
Products, because fewer moles of gas are on the right
Reactants, because more moles of gas are on the right
No change, because equilibrium is unaffected by pressure
undefined
A projectile is launched at speed v with angle theta above horizontal. Neglecting air resistance, what remains constant during flight?
Total velocity
Kinetic energy
Horizontal component of velocity
Vertical component of velocity
undefined
Which of the following is a correct inference in a syllogism: All mammals are warm-blooded. All dogs are mammals. Therefore:
Some mammals are dogs
No dogs are warm-blooded
All warm-blooded animals are dogs
All dogs are warm-blooded
undefined
Which process generates genetic variation during meiosis?
Cytokinesis
Crossing over between homologous chromosomes in prophase I
DNA replication in S phase
Separation of sister chromatids in anaphase II
undefined
The Hardy-Weinberg principle requires which condition to hold?
No selection, no mutation, no migration, random mating, and a very large population size
High gene flow and genetic drift
Frequent mutations and nonrandom mating
Strong selection and small population size
undefined
At 298 K, which reaction is spontaneous given delta H = -20 kJ/mol and delta S = -50 J/mol K?
Spontaneous, because entropy decreases
Spontaneous, because delta G = delta H - T delta S is negative at 298 K
Undetermined without K value
Nonspontaneous, because delta G = delta H - T delta S is positive
undefined
In the nephron, which segment is primarily responsible for establishing the medullary osmotic gradient?
Bowman's capsule
Loop of Henle (countercurrent multiplier)
Collecting duct epithelium only
Proximal convoluted tubule
undefined
A capacitor's stored energy is given by which expression?
U = 1/2 C V^2
U = C I^2
U = C/V
U = 1/2 V/C
undefined
Which of the following distributions has mean equal to variance?
Exponential distribution (mean equals 1/lambda, variance 1/lambda^2)
Normal distribution
Uniform distribution
Poisson distribution
undefined
Which reagent would best oxidize a secondary alcohol to a ketone without further oxidation?
PCC (pyridinium chlorochromate)
LiAlH4
NaBH4
H2, Pd/C
undefined
Which amino acid side chain is most likely to be found protonated at physiological pH? pKa side chains: Asp ~3.9, Lys ~10.5, His ~6.0, Glu ~4.1
Aspartate
Glutamate
Histidine
Lysine
undefined
A 1.0 L buffer contains 0.20 mol NH3 and 0.10 mol NH4Cl. After adding 0.05 mol HCl, which statement is correct about pH change? (Kb NH3 = 1.8e-5)
pH decreases slightly as NH3 converts to NH4+, but buffer resists large change
pH increases significantly due to added strong acid
Buffer capacity is zero so pH drops to 1
pH remains exactly constant
undefined
