BIOL 1201 : Biology 1202 Notes For First Test
Document Summary
Science- an approach to knowing the natural world. Endotherm-an animal that is dependent on or capable of the internal generation of heat; a warm-blooded animal. Ectotherm- body temperature is the same as environmental temp. Piezophile/barophile- pressure loving /bacteria grows at high pressures. Halophile- salt loving /bacteria live in osmotic equilibrium with 3 molar. Thermophile- heat loving / bacreria that exist at temps up to 132 celsius that would kill most surface organisms salt/ would kill most bacteria and grow at 122. It is very difficult to maintain body temperature. Instead of regulating body temperature fish adapt to it to save energy. Sum of neutrons and protons in an element. Number of protons in an element/electrons in a neutral atom. Know how to calculate this for atoms important in biological systems. Group 18: 8 valence electrons (except for helium, which has 2) Valence: number of electrons needed to complete the outer shell and # of chemical bonds that can be formed.
