BIOLOGY 320; FUNDAMENTALS OF ECOLOGY EXAM 2 Contrast two environments: one that you find too cold and another that you find too hot. What factors contribute to how cold to hot these environments make you feel? 1) Too hot involves intense radiation, warm or still air (little convective heat loss), and high humidity (cannot sweat effectively) 2) Too cold involves low radiation, cold or moving air (much convective heat loss), and low humidity (lose heat by evaporation) Radiat...

BIOL 320: EXAM 2 REVIEW (CH. 20, 21, 22) What are the two circulations of the heart? - CORRECT REPLY>>>>>>-Pulmonary Circulation: The right side of the heart pumps blood through the pulmonary circulation, which carries blood to the lungs, where CO2 diffuses from the blood into the lungs & O2 diffuses from the lungs into the blood. It returns the blood to the left side of the heart. - Moves blood from the right side of the heart to the lungs & back to the h...

BIOL 320 LIFE 320- EXAM 2 Adaptive evolution - CORRECT REPLY>>>>>> changes that improve the fit of organisms to their environment; response to selection (R); Mathematic approach to adaptive evolution - REPLY>>>>>> Evolution - -Evolutionary CORRECT -R= (Vg/Vp)*S; adaptive evolution = proportion of phenotypic variation due to genetics * the strength of selection CORRECT REPLY>>>>>>-Most broadly: change over time; this is...

BIOL 320 LIFE 320 Exam 2 Life Histories - CORRECT REPLY>>>>>>--The schedule of the life of an individual in a species -age of reproductive maturity -number and size of offspring -life span Lacks Proposal - CORRECT REPLY>>>>>>--life history traits contribute to fitness -life histories vary with respect to factors in the environment -hypothesis's about life histories are subject to experimental tests Lecithotrophy - CORRECT REPLY>>...

BIOL 320 Ecology Exam 2 MODULE 5 Energy Balance What is the primary source of heat gain for this organism? radiation from the sun What is the greatest source of heat loss for this organism? Contrast two environments: one that you find too cold and another that you find too hot. What factors contribute to how cold to hot these environments make you feel? Too cold: -low radiation -cold or moving air (produces more convective heat loss) -low humidity (lose heat to evaporation...

BIO 320 OLD EXAM QUESTIONS In the diagram above (from reading of Week 1), the shading of the circles indicates the phenotype of a trait and each row is a different individual (or the offspring of that individual). This diagram is demonstrating an older evolutionary theory known as: - CORRECT REPLY>>>>>>-Transformational Evolution Charnov's dimensionless ratio (c) allows for comparing the ___________ for multiple species regardless of body size and a...

BIO 320 FINAL EXAM What determines if a species can become a member of a community> How do abiotic and biotic filtering affect species sorting? - CORRECT REPLY>>>>>>-1. Adaptations of species to environmental conditions 2. Persistence in the face of competitors, predators, and parasites 3. Stochastic (random) Extinction Abiotic: environmental filters eliminate species that cannot tolerate conditions Biotic: within a community, close relative species wi...
