what are the 4 postulates of natural selection? - 1. individuals vary in their traits 2. some of the variation is heritable 3. more offspring are produced than survive to reproduce 4. survival & reproduction are predictable; those with favorable traits reproduce most and pass their genes to the next generation what happens when a proton is absorbed by a molecule? - -it excites an electron into a higher energy state -the electron quickly drops to its ground state -releases the energy as l...

Fitness - the genetic contribution of an individual to the next generation's gene pool relative to the average for the population, usually measured by the number of offspring or close kin that survive to reproductive age. Memorize the four postulates of natural selection. - 1. Individuals vary their traits 2. Some of the variation is heritable and is passed to offspring 3. More offspring are produced than survive to reproduce 4. Survival and reproduction are non-random; those with favorab...

characteristics of the net movement of all molecules? - -is predictable -directed from high to low concentration -stops when it reaches equilibrium what is the First Law of Thermodynamics? - energy can neither be created nor destroyed, but can change from one form to another the passive movement of molecules - diffusion what type of thermal movements is diffusion driven by? - Brownian characteristics of individual molecules? - -random, unpredictable motion -not directed to low concentrat...

Know the functions of the mammalian respiratory system - to supply oxygen to the cells which they need to perform cellular respiration and to rid the body of CO2 Recall the reason for 'death-zone' - people who are at a certain elevation and above for more than 48 hours get insufficient oxygen Describe the hypothesized reasons for the decline in O2 during the late Permian - Land masses form super-continent which led to a dryer climate and a reduction in photosynthesis which led to the red...

Recognize dragonflies as formidable aerial and aquatic predators - correct answer Dragonflies live in water for the first two years of their life. After this adult dragonflies hunt other flying insects while they are flying themselves; they cannot feed while walking or sitting. Identify dragonflies as ancient insects (when, what, why) - correct answer Carboniferious, meganura, first insects to fly, selection pressures Develop more than one hypothesis for why dragonflies were so big - corre...
