“Ms. Brown reminded the class that the library books were due back on Monday. On Monday morning, half the class arrived without their books.” What can be concluded?
“The nurse noticed that Mr. Diaz, usually chatty, had barely spoken all morning and had left most of his breakfast. She sat down beside him and asked how he was feeling.” Why did the nurse most likely sit down with Mr. Diaz?
Two volunteers share $480 in the ratio 7 : 9. How much x does the person with the larger share get, in dollars?
A recipe uses 9 cups of flour for 6 batches of muffins. At the same rate, how many cups of flour x are needed for 11 batches?
Which part of the brain is chiefly responsible for coordination and balance?
Which coronary artery most often supplies the sinoatrial (SA) node?
Why do myelinated axons conduct action potentials faster than unmyelinated ones?
In long-standing aortic stenosis, how does the left ventricle adapt?
Where does the Krebs (citric acid) cycle take place in a eukaryotic cell?
Muscle cells use a lot of energy. Which organelle would you expect them to have in large numbers?
What are London dispersion forces?
Samples of hydrogen gas (H₂) and oxygen gas (O₂) are at the same temperature. Which statement is correct?
What is the subject of this sentence? “Behind the curtain stood a tall man.”
Which revision best corrects the shift from active to passive voice? “The nurse checked the chart, and then the medication was given by her.”
Choose the meaning of the word in bold: “Aspirin is contraindicated in children with viral infections.”
Choose the meaning of the word in bold: “The sudden drop in blood pressure was transient.”
Answer: A · Some students forgot the reminder.
Ms. Brown did give the reminder, yet half the class came without their books, so some students forgot (or ignored) it.
Answer: A · She noticed a change in his usual behaviour.
A normally chatty patient who is quiet and not eating has changed in behaviour. The nurse sits down to find out why, which can reveal pain, worry or illness.
Answer: x = 270 $
Ratios and proportions: a ratio a : b compares two amounts. In a proportion two ratios are equal, a/b = c/d, and you solve it by cross-multiplying: a·d = b·c. To share an amount in the ratio m : n, divide it into m + n equal parts; one share is m parts, the other n parts.

Answer: A · Cerebellum
The cerebellum fine-tunes movement, posture and balance. Damage causes ataxia and an unsteady gait.
Answer: A · Right coronary artery
The SA nodal artery arises from the right coronary artery in roughly 60% of people and from the circumflex artery in the rest.
Answer: C · The impulse jumps between nodes of Ranvier
Myelin insulates the axon, so action potentials are only generated at the nodes of Ranvier. This saltatory conduction is much faster.
Answer: C · Concentric hypertrophy with a thicker wall
Pressure overload makes the ventricular wall thicken (concentric hypertrophy) to keep wall stress normal. Volume overload, as in regurgitation, causes dilation instead.
Answer: D · In the mitochondrial matrix
Pyruvate from glycolysis enters the mitochondria, and the Krebs cycle runs in the matrix, the fluid inside the inner membrane. The electron transport chain sits in the inner membrane itself.
Answer: A · Mitochondria
Active muscle needs a lot of ATP, so muscle cells are packed with mitochondria, where aerobic respiration takes place.
Answer: C · Weak, temporary attractions caused by shifting electrons in molecules
At any moment, electrons can be unevenly spread, creating a temporary dipole that induces dipoles in neighbours. These weak attractions are the only forces between nonpolar molecules and noble gas atoms.
Answer: B · They have the same average kinetic energy, but H₂ molecules move faster
At the same temperature, all gases have the same average kinetic energy. Because KE = ½mv², the lighter H₂ molecules must move faster to have the same energy as heavier O₂ molecules.
Answer: B · man
The sentence means “A tall man stood behind the curtain.” The subject is “man”; “curtain” is the object of the preposition.
Answer: B · The nurse checked the chart and then gave the medication.
A keeps both verbs in the active voice with “the nurse” as the subject. B and D still mix passive and active, and C stays passive in the second clause.
Answer: D · Not advised because it may cause harm
A treatment is contraindicated when a condition makes it unsafe to use.
Answer: C · Lasting only a short time
Transient means temporary or short-lived.
