Model Answer
Gland and Hormone: In scary situations, the adrenal glands (located on top of the kidneys) secrete the hormone adrenaline into the blood.
Two responses shown by the body:
- Heart beats faster — resulting in more oxygen supply to the muscles.
- Breathing rate increases — due to contractions of the diaphragm and rib muscles, supplying more oxygen to the body.
(Other valid responses: blood is diverted from digestive system/skin to skeletal muscles; contraction of muscles around small arteries in digestive system and skin.)

Explanation
- Examiners expect: name of gland (adrenal) + name of hormone (adrenaline) — both needed for full credit.
- Two responses must be distinct body changes; don't repeat the same idea in different words.
- Common mistakes: writing "kidney gland" instead of adrenal gland, or giving vague responses like "body becomes active."
- The question is 3 marks: 1 mark for gland + hormone, 1 mark each for two responses.
