Which ABO blood group has both anti-A and anti-B antibodies in the plasma?
Which spirometry finding is typical of chronic obstructive pulmonary disease (COPD)?
A cell has a nucleus and mitochondria but no cell wall and no chloroplasts. What kind of cell is it most likely to be?
Two pea plants that are both AaBb are crossed. The genes are on different chromosomes. What fraction of the offspring is expected to show both recessive traits (aabb)?

What is the net ionic equation for the neutralisation of any strong acid by any strong base?
Which spelling is correct for the word that means “a disagreement”?
Which sentence clearly means that she likes her patients more than her coworkers like them?
Choose the meaning of the word in bold: “Apply the topical cream to the rash twice a day.”
Choose the meaning of the word in bold: “His symptoms were intermittent.”
Answer: B · Cheerful
A warm spring day with kites, picnics and friends chatting creates a cheerful, happy mood.
Answer: D · The factory closing hurt the wider town.
After the factory closed, shops shut and buses were cut, suggesting that the loss of the factory harmed the town’s economy.
Answer: x = 76 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 = 105 $
Reverse percentages: when a value has already been increased or decreased by a percent, the new value is a percent of the original, not the other way round. After a 20% discount the price is 80% of the original, so original = new price ÷ 0.80. Never add the 20% back on to the new price.
Answer: B · Scaphoid
The scaphoid is the most often fractured carpal bone. Tenderness in the anatomical snuffbox is a key clinical sign.
Answer: A · Right-sided weakness and aphasia
The left MCA supplies the left motor cortex (face and arm of the right side) and Broca's and Wernicke's areas, so right hemiparesis with aphasia is typical.
Answer: A · Group O
Group O people have no A or B antigens and make both anti-A and anti-B. Group AB has both antigens and neither antibody.
Answer: A · FEV1/FVC ratio below 0.7
Narrowed airways slow expiration, so FEV1 falls more than FVC and the ratio drops below 0.7. In COPD this is not fully reversed by bronchodilators.
Answer: C · An animal cell
A nucleus and mitochondria show it is eukaryotic. Plant and fungal cells both have cell walls, and plant cells have chloroplasts, so the cell is most likely an animal cell.
Answer: A · 1/16
P(aa) = 1/4 and P(bb) = 1/4, and the genes assort independently, so P(aabb) = 1/4 × 1/4 = 1/16. The full ratio is 9 : 3 : 3 : 1.
Answer: D · Acidosis
A blood pH below 7.35 is acidosis, even though 7.25 is still above 7 on the pH scale. "Acidosis" means more acidic than normal for blood, not necessarily below pH 7.
Answer: C · H⁺ + OH⁻ → H₂O
Strong acids and bases are fully ionised, so their other ions (such as Na⁺ and Cl⁻) are spectators. The only actual change is H⁺ combining with OH⁻ to form water.
Answer: B · argument
“Argument” is an exception to the rule of keeping the silent e before a consonant suffix: argue → argument.
Answer: C · She likes her patients more than her coworkers do.
“More than her coworkers do” compares how much she and her coworkers like the patients. B compares the patients with the coworkers instead, and C and D change the meaning.
Answer: C · Applied to the surface of the body
A topical medication is applied directly to the skin or another body surface.
Answer: C · Coming and going at intervals
Intermittent means stopping and starting at intervals, not continuous.
