A. prokaryotes do not generate energy
B. prokaryotes produce energy via photosynthesis
C. prokaryotes have specialized mitochondria

Sn1 reactions show first-order kinetics because:
A. the rate-limiting step is the first step to occur in the reaction
B. the rate-limiting step involves only one molecule
C. there is only one rate-limiting step
D. the reaction involves only one molecule
B. the rate-limiting step involves only one molecule
An SN1 reaction is a first-order nucleophilic substitution reaction. It is called first-order because the rate-limiting step involves only one molecule. Choice (A) is true, but does not explain why SN1 reactions have first-order kinetics; the rate- limiting step of an SN2 reaction is also the first (and only) step of that reaction, but SN2 reactions have second-order kinetics, not first-order. Choice (C) is a true statement as well, but again does not explain why the reaction is first- order. Finally, choice (D) is incorrect because it is the rate- limiting step, not the reaction overall, that involves only one molecule.
In which of the following cases will the normal force on a box be the greatest?
A. When the box is placed in a stationary elevator

C. When the box is placed in an elevator accelerating downward
D. When the box is placed in an elevator accelerating upward
D. When the box is placed in an elevator accelerating upward

Acetylation of lysine residues in histones increases gene expression because:
A. DNA is tightly bound to negatively charged amino acids on histones.
B. the carboxyl oxygen atoms in acetyl groups form hydrogen bonds with nitrogenous bases.
C. the salt bridges between charged amino acids and phosphate groups are disrupted.
D. lysine residues in histones associate with positively charged phosphate groups in DNA.
B. The salt bridges between charged amino acids and phosphate groups are disrupted.
What is the most specific characterization of the reaction shown?:
Ca(OH)2 (aq) + H2SO4 (aq) → CaSO4 (aq) + H2O (l)
A. Single-displacement
B. Neutralization
C. Double-displacement
D. Oxidation–reduction
B. Neutralization
The correct answer is: B
This reaction is a classic example of a neutralization reaction, in which an acid and a base react to form a salt and, usually, water. Although this reaction also fits the criteria for a double- displacement reaction, choice (C), in which two molecules essentially exchange ions with each other, neutralization is a more specific description of the process.
A man walks 30 m east and then 40 m north. What is the difference between his traveled distance and his displacement?
A. 0 m
B. 20 m
C. 50 m
D. 70 m
B. 20 m
Use the Pythagorean Theorem.
302+402=50. 70-50=20. His total distance traveled is equal to 30 + 40 = 70 m. Therefore, the difference between these two is 20 m.

B. Behavioral neuroscience
C. Clinical neuropsychology
D. Psychosomatic Therapy
A.Behavioral genetics

An unknown molecule is added to an enzyme-catalyzed reaction, immediately decreasing its rat. If the addition of more substrate has no effect, but the addition of an antibody for the unknown molecule restores the initial reaction rate, what form of inhibition is most likely occurring?
A. feedback inhibition
B. competitive inhibition
C. uncompetitive inhibition
D. irreversible inhibition
E. noncompetitive inhibition
E. noncompetitive inhibition
In a certain equilibrium process, the activation energy of the forward reaction is greater than the activation energy of the reverse reaction. This reaction is:
A. Endothermic
B. Exothermic
C. Spontaneous
D. Nonspontaneous
D. Nonspontaneous
The products have a higher free energy than the reactants. There is not enough information available to determine entropy change, therefore endothermic and exothermic, choices (A) and (B), are excluded.
Which of the following cannot be measured simultaneously, according to the Heisenberg uncertainty principle?
A. Direction and velocity
B. Placement and displacement
C. The first is speed and acceleration
D. The composition and rate of acceleration
A. Direction and Velocity

B.Psychological approach
C. Sociocultural approach
D. Heisenberg Uncertainty Principle
B.Psychological approach

Choose the option that best describes what the basal layer of the epidermis and the innermost lining of the small intestine have in common.
A) The two are non-dividing tissues.
B) They are both derived from ectoderm.
C) The two are made up of squamous cells.
D) The cells of each option are connected by tight junctions.
D) The cells of each option are connected by tight junctions.
The cells of both the basal layer of the epidermis and the innermost lining of the small intestine are connected by tight junctions. This question calls upon your knowledge of the structural and embryological characteristics of both tissues.

B. There will be a four-fold increase.
C. The amount will fall by a factor of 2.
D. The amount will fall by a factor of 4.
D. The amount will fall by a factor of 4.
