2Solutions
1.Human anatomy
Answer: B · Cerebellum
Why this is the answer
The cerebellum fine-tunes movement, posture and balance. Damage causes ataxia and an unsteady gait.
Answer
B · Cerebellum
2.Human anatomy
Answer: A · Left-sided weakness and loss of proprioception, right-sided loss of pain and temperature
Why this is the answer
In Brown-Séquard syndrome the corticospinal tract and dorsal columns are lost on the same side, while the spinothalamic tract, which crosses near entry, causes contralateral pain and temperature loss.
Answer
A · Left-sided weakness and loss of proprioception, right-sided loss of pain and temperature
3.Human physiology
Answer: A · Group O
Why this is the answer
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 · Group O
4.Human physiology
Answer: D · Undigested lactose draws water into the gut and is fermented by colonic bacteria
Why this is the answer
Unabsorbed lactose acts osmotically, pulling water into the lumen. Colonic bacteria ferment it, producing gas and short-chain fatty acids.
Answer
D · Undigested lactose draws water into the gut and is fermented by colonic bacteria
