BIOL 1201 Chapter : Biology Learning Objectives 1 ANSWERED
Document Summary
Science: an approach to understanding the natural world. Endotherm(ic): referring to organisms that are warmed by heat generated by their own metabolism. This heat usually maintains a relatively stable body temperature higher than that of the external environment. Ectotherm(ic): referring to organisms for which external sources provide most of the heat for temperature regulation. Piezophile/barophile: bacteria piezophiles are pressure loving; they thrive at pressure that kills surface bacteria. Halophile: does very well at high salt concentrations. Because they are cold-blooded so they can accumulate a range of temperatures. Number of protons and in a neutral atom, the number of electrons also. Know how to calculate this for atoms important in biological systems. The valence of an atom is the number of electrons it needs to complete its outer shell. It is important because the valence is what the atom needs to become stable.
