1.
A student described the formation and elimination of urine as follows. In which step is the error? Step 1: Blood is filtered from the glomerulus into Bowman's capsule. Step 2: The filtrate passes through the renal tubule, where water and glucose are reabsorbed. Step 3: Urine collects in the collecting duct and then the ureter. Step 4: Urine moves from the ureter to the urethra and is then stored in the bladder.

During muscle contraction, calcium ions bind to

troponin
tropomyosin
myosin
actin directly
3.

Depolarisation during an action potential is caused by

voltage-gated sodium ion channels opening and Na⁺ diffusing in
K⁺ diffusing out
Na⁺ being pumped out
Ca²⁺ leaving
4.
Breathing rate and heart rate during exercise are shown. What explains both rising?
Exercise lowers oxygen demand
Muscles need more oxygen delivered and more CO₂ removed
The lungs make glucose
Blood stops circulating
5.

Which drug action in the table prolongs the signal by keeping transmitter in the synapse?
Blocking receptors
Blocking reuptake
Reducing release
Destroying vesicles
9.
Saltatory conduction occurs because:
Axons are wider
Temperature is higher
Myelin restricts depolarisation to nodes of Ranvier
K+ channels are absent
10.
Glucose test strips are used to test simulated urine samples. What does a positive result suggest?
Healthy kidneys
Too much iodine
Possible diabetes
High ADH
11.

At a cholinergic synapse, the arrival of an action potential causes

sodium ions to leave
acetylcholine to enter the knob
calcium ions to enter the presynaptic knob
the cleft to close
