Document Summary
Which is not an example of convergent evolution: an ant having long legs to keep its body away from hot sand. Single celled organisms are the only species, which can exchange with its environment directly: true. The body"s automatic tendency to maintain a constant and optimal internal environment is termed: homeostasis. Internal temperature is the only metabolic process regulated by homeostasis: false. The panting responses that are observed in overheated birds and mammals dissipate excess heat by: evaporation. Which would increase the rate of heat exchange between an animal and its environment: wind blowing on surface of body. Hummingbirds are small birds that require a regular food supply. Animals with large surface areas but small volumes have higher metabolic rates: true. Evolution of animal size and shape: convergent evolution: the independent evolution of similar features in species of different lineages.
