Microbe CORRECT ANSWER -Free living organisms so small that they are only visible under the microscope. -Viruses are not really microbes- they lack one key quality of living cells; the capacity to main their bodily integrity throughout their life cycle. -Exceptions: Epulopiscium fishelsoni is huge (600+ um), Mycobacterium leprae is not free living. -Bacteria, Archaea, Fungi, Protists. LUCA CORRECT ANSWER -Last Universal Common Ancestor= microbe -About 4 bya -Core features for cellular...

The scientific discipline of naming and classifying organisms - Answer-taxonomy Two part format of a scientific name (Genus species) - Answer-binomial grouping of species into increasingly inclusive categories - Answer-hierarchical classification The named unit at any level of the hierarchy - Answer-taxon The evolutionary history of a species or group of species - Answer-phylogeny A discipline focused on classifying organisms and determining their evolutionary relationships - Answersystemat...

Evolution - The change in allele frequencies in a population over time Selection - Changes in allele frequencies due to organisms with advantageous alleles reproducing more successfully than organisms with other alleles Genetic Drift - Random changes in allele frequencies in a population Mutation - The source of all new allelic diversity Migration - Movement of alleles between populations Adaptation - A trait that evolves by selection for a particular function (because it increases fitness...

List the 7 most widely accepted characteristics of living organisms correct answers Order, evolutionary adaptation, regulation, energy processing, growth and development, response to the environment, and reproduction Describe evolutionary adaptation and give an example correct answers refers to smaller, genetic changes that allow for better survival of an organism. An example would be camouflage because if an animal can camouflage with their environment they will ideally live longer and be ...
