Which route carries urine from the kidneys to the exterior?

  1. Urethra → bladder → ureters
  2. Ureters → urethra → bladder
  3. Ureters → bladder → urethra
  4. Bladder → ureters → urethra
Show answer and solution

Correct answer: C. Ureters → bladder → urethra

The paired kidneys form urine, which passes through the paired ureters into the urinary bladder for storage. Urine is released to the exterior through the urethra during micturition.

Which animal–respiratory structure pairing is correct?

  1. Earthworm — gills
  2. Insect — lungs
  3. Fish — moist cuticle
  4. Frog — lungs and moist skin
Show answer and solution

Correct answer: D. Frog — lungs and moist skin

Frogs use lungs and also their moist skin. Earthworms exchange gases through moist cuticle, insects through tracheal tubes, and fishes through gills. Sponges exchange gases by diffusion across the body surface.

Which blood component–function pairing is correct?

  1. RBCs — antibody production
  2. Platelets — oxygen carriage
  3. Leucocytes — body defence
  4. Haemoglobin — fibrin formation
Show answer and solution

Correct answer: C. Leucocytes — body defence

Leucocytes participate in defence, including phagocytosis and immune responses. RBC haemoglobin transports oxygen. Platelets release factors involved in coagulation; fibrin forms from fibrinogen.
