There appears to be a deficiency in the brains ability to produce or use certain chemicals called transmitter substances or neurotransmitters. The theory is that a shortage of certain neurotransmitters results in the brain being under-stimulated, therefore it's deficie...
Adaptions in Ectothermic and Endothermic animals to extreme climates First of all we need to understand what ectothermic and endothermic animals are. Animals differ in their abilities to regulate body temperature (thermoregulation). We sometimes use the terms "cold-blooded" or "warm-blooded." Most reptiles feel cold to the touch, while...
