BIOL 1201 : Test 1 Study Guide
Document Summary
Science: an approach to understanding the natural world. Endotherm: organisms warmed by heat that are generated by their own metabolism. This heat usually maintains a stable body temp higher than the external environment: ex: penguins, humans, tuna, great whites, etc. Ectotherm: organisms for which external sources provide most of the heat for temperature regulation (body temp set by environmental temperature, ex: crabs, antarctic fishes (not all fish are ecto though) Piezophile/barophile: another word for pressure loving , a bacteria that thrives at pressures that kill surface bacteria. Halophile: halophilic bacteria live in osmotic equilibrium with 3 molar salt, halophiles love high salt. Thermophile: bacteria that can exist at temperatures up to 132 degrees c (& grow at 122 c) What are some examples of endotherms and ectotherms: endotherms: penguins, humans, tuna, great whites, swordfish, ectotherms: crabs, antarctic fishes (not all fish are ecto though)
