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...

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...

TEST 2: Bio 1500 Mizzou Schul; Questions and Answers 100% Pass Categorize different energy forms as 'kinetic' or 'potential' CORRECT ANS-Kinetic energy: the energy of movement □ Includes heat, light, electricity Potential energy: stored energy □ Includes chemical energy □ You can store energy in chemical bo

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...

EXAM: Bio 1500 Mizzou Schul TEST 4 with Verified Answers residual lung volume CORRECT ANS-amount of air left in the lungs after exhaling Explain why residual lung volume exists CORRECT ANS-keep the alveoli open even after maximum expiration which allows for continual gas exchange to occur between breaths.

Categorize different energy forms as 'kinetic' or 'potential' - Kinetic energy: the energy of movement □ Includes heat, light, electricity Potential energy: stored energy □ Includes chemical energy □ You can store energy in chemical bonds Apply the First Law of Thermodynamics - Energy is never created or destroyed, but it can change form Describe the mechanism of diffusion at the level of single particles - particles move from high to low concentration Describe the patt...

residual lung volume - amount of air left in the lungs after exhaling Explain why residual lung volume exists - keep the alveoli open even after maximum expiration which allows for continual gas exchange to occur between breaths. Explain how the circular processes of photosynthesis and cellular respiration result in the cycling of carbon within ecosystems. - CR produces CO2 and water which PS uses to make O2 and glucose which CR uses Explain the two reasons for an imbalance in this cycl...
