What are the 4 types of thermoregulation strategies? {Ans: -Endotherms -Ectotherms -Kleptotherms -Poikilotherms}Main cellular ions involved in exchange with the environment during osmoregulation? {Ans: Na+, K+, Ca2+, Cl-, PO43-}What are the 5 types of thermoregulation? {Ans: -Metabolic heat production -Insulation -Circulatory system adaptations -Evaporate cooling -Behavioral responses}What is radiation? {Ans: The absorption or emission of electromagnetic waves}What is urea? {Ans: -Less toxic, but still relatively soluble.​ -Can be accumulated to higher concentrations.​ -Allows for conservation of body water, but . . .​ -Must be excreted with water; requires drinking.​ -Toxic (denatures proteins) at high concentrations.}Origins of Cellular Solutes Involved in Osmoregulation? {Ans: -Breakdown of food substances.​ -Ingestion / Uptake / Exchange of various ions from / with the environment​}What is a kleptotherm? {Ans: Any form by which an animal shares in/steals from the metabolic thermogenesis of another animal (penguins)}What is ammonia? {Ans: -Very soluble, but relatively toxic.​ -Can not accumulate to high concentrations.​ -Requires a lot of water for excretion.​ -Excreted via gills & skin surfaces.}What is uric acid? {Ans: -Non-toxic substance, with poor solubility in water.​ -Can be made highly concentrated.​ -Allows maximum water conservation.​ -Requires more complex metabolism &
