3. REVEALING TRADE-OFFS: THE USE OF MULTIVARIATE QUANTITATIVE GENETICS 3.1. Life-History Trade-Offs and Genetic Correlations The existence of trade-offs between different components of fitness is fundamental to much of life-history theory. If these constraints are to affect evolutionary processes, which evolutionary ecologists typically assume they will, they must have a genetic basis, requiring the action of either antagonistic pleiotropy or linked genes with antagonistic effects, and the...

Which characteristic of a cell most influences the rate of movement of materials into and out of the cell? Surface Area Compared with a smaller cell, a larger cell of the same shape has ________. less surface area per unit of volume When are my office hours? Monday through Thursday 1-2pm, but you can make alternative arrangements. In class, we discussed many examples of why a high surface area to volume ratio is an advantage to organisms. The mammal outer surface in a very cold environment co...

Temperature ANSWER = a measure of the average kinetic energy of the molecules of a substance Macroclimate ANSWER = Prevailing weather conditions over long time peruod Microclimate ANSWER = Small scale weather variation over shorter time periods Ex: flower Altitude ANSWER = Atmospheric pressure decreases with elevation with air expanding and cooling Specific heat ANSWER = Water absorbs heat energy without changing temperatures Latent heat of evaporation ANSWER = Water also absorbs he...

Bio 150 final jmu Correct Questions & Soluti Biodiversity is measurable at three levels: - ANSWER Genetic level= variability within species Species level= variability among species Ecosystem level= variability among ecosystems Three domains of life: - ANSWER Archaea, eukarya and bacteria Population - ANSWER interbreeding group of individuals. Populations exchange genes Purpose variability within a population - ANSWER 1. some genetic variants have advantages over others 2. natural se...

Life Science 15 Phelan Graded A+ Evolution ️A change in allele frequencies over time. Allele ️A variant form of a gene. Gene ️A segment of DNA that provides instructions for producing a trait. Natural Selection ️Involves variation, heritability, and differential reproductive success. Fitness ️The relative reproductive success of a genotype or phenotype. Four Agents of Evolution ️Natural selection, mutation, gene flow, genetic drift. Natural Selection ️Non-random elimination ...

Criteria for natural selection - Answer variation, heritable, influences fitness natural selection acts on __________ and evolutionary change acts on _____________ - Answer individuals, populations Artificial selection - Answer driven by humans selectively breeding How fast/far can artificial selection go? - Answer FAST -depends on how many genes -how much the phenotype is controlled by the environment FAR -presence of deleterious trade offs -limits of the genetic variation availab...

ITPM chapter 8 Questions with 100% Correct Answers T/F: The quality assurance process involves taking responsibility for quality throughout the project's life cycle. True T/F: Validated changes and validated deliverables are the outputs of the quality assurance process. False T/F: The design of experiments technique cannot be applied to project management issues such as cost and schedule trade-offs False T/F: Customer requirements are an important aspect of the quality plann...

change from gen to gen via selection of heritable traits evidence for evolution - Answer - fossils - extinction - transitional forms - vestigial traits why is the myth about evolution being goal oriented false? - Answer species do not adapt because they "want" or "need" traits; they adapt them because an ancestor with that triat just so happened to reproduce sooner or more successfully than others why is the myth that evolution is a hierachy false? - Answer evolution is more a ne...
