Practice question

60–75% (C) is the right choice. This sits at the heart of Thermoregulation: the wording points straight to what is happening in the tissue or organ system. A useful study habit is to ask what the structure or process is for: 60–75% is the option that correctly names the structure, process, or principle asked for in Thermoregulation. That reasoning supports 60–75%. One solid sentence about why this works is enough for recall — you do not need a long essay for every MCQ. When you practise, cover the choices first, write 60–75% from memory, then reveal the letter — that habit builds real recall for Thermoregulation.
