Compare thermoregulation in ectotherms and endotherms
Similarities - regulation of body temperature to maintain homeostasis
Differences - ectotherms are reliant on external environments so they may use behavioural adaptation such as moving to the shade.
Endotherms have physiological adaptations such as as shivering or sweating to regulate body temp.
Briefly explain the cause and effect of one disease caused by nutritional deficiency
Anaemia (unable to carry oxygen to tissues) - lack of iron
Blindness - lack of vitamin A
