Ordered complexity 6. Evolutionary adaptation 7. Sensitivity Survival - -Which of the following is not shared by all organisms? a Growth b Survival c Sensitivity d Ordered complexity e energy utilization Independent Variable - -The condition; changes Dependent variable - -Measured qualitative data - -data observed but can not be measured; Descriptions quantitaive data - -can be measured; numbers c organism, population, ecosystem, biosphere - -Which of the following is the biological organization of hierarchical ordered complexity of life that we will be covering in this course? Population, ecosystem, biosphere, species b. Cell, population, ecosystem, biosphere, organisms c. Organism, population, ecosystem, biosphere d. Cell, organism, biosphere, ecosystem, community e. Population, biosphere, ecosystem, community f. Cell, species, ecosystem, biosphere g. Ecosystem, population, community, biosphere h. Species, population, biosphere, organisms, ecosystem cell - -Fundamental unit of life Organismal level - -animal in a hierarchal organization Population level - -species in a hierarchal organization Ecosystem level - -Animals and environment in a hierarchal organization Biosphere - -Whole world in a hierarchal organization False This will not result in evolution.This is an example of Lamarckian theory; it will not lead to changes in a population because the changes that have occurred are not heritable / will not be inherited by the offspring. - -True or False? The following scenario is likely to result in evolution: A pregnant woman spends too much time in the sun and suffers severe sunburn.The sunlight causes genetic changes to the DNA in her skin. True This is likely to result in evolution since heritable changes are occurring in the DNA of germ-line cells of the population that is allowing the colonizing plants to be resistant to the metal toxicity. Thus, it is likely that future offspring will inherit these traits as well. - -True or False? The following scenario is likely to result in evolution: Toxic levels of heavy metals are dumped as waste from coal mines. Initially, no plants will grow on the waste dump; but eventually, some grasses begin to colonize the dump sites and reproduce. d. inheriting acquired characteristics - -Darwin's work on the Galapagos Islands led him to derive all of the following concepts, EXCEPT: a. Evolutionary adaptation b. Natural selection c. Heritable variation d. Inheriting acquired characteristics Lamarck - -Who derived inheriting acquired characteristics? c. Bottleneck effect - -Northern elephant seals have reduced genetic variation most likely due to being hunted. Hunting reduced their population size to as few as 20 individuals at the end of the 19th century. Since then, their population has rebounded to over 30,000, but the genes still have much less variation than the genes in a population of Southern elephant seals that were never hunted. This is an example of... a. Founder Effect b. mutation c. Bottleneck Effect
