Problem
Homeostasis: Osmotic Regulation, Excretion, and Temperature Regulation
i. Compare excretory structures of single-celled organisms with those of marine invertebrates and terrestrial vertebrates.
ii. Briefly describe the function and role of the following: aldosterone, renin, angiotensin, and antidiuretic hormone
iii. Some insects are "facultative endotherms," which means they can warm up parts of their body, such as the thorax, by muscular thermogenesis. How does this compare to the endothermy found in most mammals and birds?
