Question 2 · 1 mark · Difficulty 1/3
Which part of the body monitors the temperature of the blood and acts as the control centre for body temperature?
- The thyroid gland
- Receptors in the skin
- The hypothalamus
- The cerebellum
Show answer & explanation
✓ Answer: C — The hypothalamus
Award 1 mark. The hypothalamus contains receptors that monitor the temperature of the blood flowing through the brain, and it acts as the control centre by triggering sweating, vasodilation or shivering. The thyroid gland is wrong because, although the hormone it releases raises metabolic heat production, it does not detect blood temperature. Receptors in the skin are wrong because they monitor external temperature and only send impulses to the control centre. The cerebellum is wrong because it coordinates balance and movement.

WJEC GCSE Biology: Homeostasis FAQ
Is Kramizo free for WJEC GCSE students preparing for Biology?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Homeostasis practice with other Biology topics or even switch to a totally different WJEC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Homeostasis questions aligned to the official WJEC GCSE Biology syllabus?
Every question is written against the published WJEC GCSE Biology specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real WJEC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from WJEC.
How is Homeostasis typically tested on WJEC GCSE Biology papers?
Homeostasis appears across multiple question types on real WJEC GCSE Biology papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
