Formula sheets, the key method steps for every topic and 16 practice problems, with full solutions at the back.
“Using phones and tablets late at night may make it harder to fall asleep. Experts suggest putting screens away about an hour before bed.” Which person is following the experts’ advice?
A school sends this note: “Due to the forecast of heavy snow, all classes will move online on Friday. Students should log in at the usual time. The building will be closed.” Which statement is NOT supported by the note?
A bookshelf is 7 ft 2 in tall. How many inches x is that?
Solve for x: 3(x − 4) = 7x − 20.
Which type of epithelium lines most of the trachea?
After a stroke, a patient speaks fluently but uses meaningless words and cannot understand speech. Where is the lesion most likely to be?
What is the main stimulus for breathing in a healthy person?
A young woman has muscle weakness that gets worse with repeated use and improves with an acetylcholinesterase inhibitor. What is the most likely mechanism?
Which polymer is correctly matched with its monomer?
People who carry one sickle cell allele are more resistant to malaria. Why is the allele common in regions where malaria is widespread?
Why does keeping food in a refrigerator slow down spoilage?
Hyperbaric oxygen therapy places a patient in a chamber with oxygen at higher than normal pressure. Why does this raise the oxygen dissolved in blood plasma?
Choose the correct verb: “Both of the nurses ___ on duty tonight.”
Which choice best combines the sentences to show cause and effect? “The patient skipped breakfast. She felt faint during the test.”
Choose the meaning of the word in bold: “Patient safety is paramount.”
What does the term angioplasty mean?
Answer: D · Ana, who reads a paper book for the last hour
Experts suggest putting screens away an hour before bed. Only Ana does this, reading a paper book instead.
Answer: D · Classes on Friday are cancelled entirely.
The note says classes move online, not that they are cancelled. The other three statements are directly supported.
Answer: x = 86 in
Unit conversions: multiply by a factor that equals 1, written so that the old unit cancels: 3 ft × 12 in/1 ft = 36 in. Metric length: 1 km = 1000 m, 1 m = 100 cm = 1000 mm, 1 cm = 10 mm. US customary: 1 ft = 12 in, 1 yd = 3 ft, 1 mi = 5280 ft; 1 gal = 4 qt, 1 qt = 2 pt, 1 pt = 2 cups; 1 ton = 2000 lb. Time: 1 h = 60 min, 1 min = 60 s, 1 day = 24 h, 1 week = 7 days. A smaller unit gives a bigger number.
Answer: x = 2
Solving equations: do the same thing to both sides until x stands alone. Undo operations in reverse order: first undo addition or subtraction, then multiplication or division. Clear parentheses with the distributive property, a(x + b) = ax + ab, and collect the x terms on one side. Check the answer by substituting it back.
Answer: D · Pseudostratified ciliated columnar epithelium
Respiratory epithelium is pseudostratified ciliated columnar with goblet cells. Mucus traps particles and cilia move it up towards the pharynx.
Answer: C · Posterior superior temporal gyrus of the dominant hemisphere
This is Wernicke's (receptive) aphasia, caused by damage to Wernicke's area in the posterior superior temporal gyrus. Broca's area in the inferior frontal gyrus causes non-fluent aphasia.
Answer: C · A rise in arterial CO₂
Central chemoreceptors respond to CO₂ (through the pH of the cerebrospinal fluid). Low O₂ adds strongly to the drive only when PaO₂ falls well below normal, for example at high altitude.
Answer: D · Antibodies against acetylcholine receptors at the neuromuscular junction
In myasthenia gravis, autoantibodies reduce the number of functional acetylcholine receptors. Blocking acetylcholinesterase leaves more ACh to bind the remaining receptors.
Answer: C · Starch and glucose
Starch and glycogen are polymers of glucose, proteins are polymers of amino acids and DNA is a polymer of nucleotides. Fatty acids are parts of lipids, which are not true polymers.
Answer: D · Natural selection favours the heterozygotes there
Heterozygotes are protected against malaria and do not have sickle cell disease, so they survive and reproduce more. This heterozygote advantage keeps the allele common even though homozygotes are ill.
Answer: B · Lower temperatures slow down chemical and microbial reactions
At lower temperatures, fewer particles have enough energy to react, and microbial enzymes work slowly. Spoilage reactions therefore happen more slowly. The activation energy itself does not change.
Answer: D · Gas solubility in a liquid increases with the partial pressure of the gas
Henry's law states that the amount of gas dissolving in a liquid is proportional to its partial pressure above the liquid. Raising the oxygen partial pressure dissolves more O₂ in plasma.
Answer: D · are
“Both” is a plural indefinite pronoun, so it takes a plural verb. Few, many, several and both are always plural.
Answer: A · Because the patient skipped breakfast, she felt faint during the test.
“Because” shows that skipping breakfast caused the faintness. “And” only adds ideas, and “although” and “but” wrongly suggest contrast.
Answer: A · Most important
Paramount means more important than anything else.
Answer: A · Surgical repair or widening of a blood vessel
Angioplasty is a procedure to repair or open a narrowed blood vessel, often with a balloon.
