Homeostasis Puzzles

Three puzzles based on exam question answers for A level homeostasis.

1. Cryptogram - based on an AQA exam question on blood glucose and insulin.
2. Wordsearch - where the gaps left between the words spell out a secret message about the importance of maintaining body temperature based on an AQA exam question.
3. Letter tiles - when arranged correctly give a model answer on the action of ADH - this one is really fiendish - but one of my year 13s did manage it. The answer is: “Decreasing water potential of the blood is detected by receptors in the hypothalamus. ADH is released from the pituitary which makes cells in the collecting duct more permeable to water. Water leaves the filtrate by osmosis and a smaller volume of water is produced.”
