Document Summary

1. the method that is currently most used to determine evolutionary relationships between bacteria is: Dna fingerprinting: the definition of a species as a group of closely related organisms that can interbreed applies to: Viral species: in the taxonomic hierarchy, a group of similar families is a/an: Domain: the first step in the identification of a bacterium is often: Gram-staining: the proposed evolutionary history of a group of organisms can be visually represented by: A cladogram: how many bacterial species do you think are in a typical gram of soil? usually < 10 dozens. Deuteromycota: true or false: all fungi are heterotrophic. False: most yeasts, such as saccharomyces, reproduce by an uneven, asymmetrical cell division called: Deuteromycota: lichens consist of a mutualistic relationship between: Protozoa and algae: mycorrhizae consist of a mutualistic relationship between: Mutualistic symbiont (e. g. in a lichen or mycorrhiza) They photosynthesize it: the organisms responsible for irish potato blight and california.
