function properly in the correct conditions. Regulating factors such as temperature‚ requires considerable amounts of energy and complex mechanisms to keep these functions within defined limits. The regulation of body temperature is called thermoregulation. Most chemical reactions have an optimal activity; they work best under specific conditions. Enzymes‚ for example are most active at specific temperature and PH. In humans enzymes are most active at the regulated body temperature of 37 degrees

Antarctic penguins have a wide range of adaptations that help them to survive in the hostile and extreme environment they call home. This essay will look at the key adaptations that these birds have and compare different species to outline the importance of the different morphological‚ physiological and behavioral features that allow them too survive in their environment. The most obvious morphological adaptation is that of size. Penguins that reside on the Antarctic continent are larger in
