Most prokaryotes require water availability (aw) to be greater then? ~ aw>0.91 Aquaporins ~ channel proteins that facilitate the passage of water (protect against osmotic stress) Halophiles ~ salt loving mechanosensitive channels ~ pressure sensitive channels that leak solutes from the cell, lowering cytoplasmic osmolarity Acidophiles ~ grow best in acidic habitats pH homeostasis ~ K+/H+ (acid) or Na+/

UTA-Microbiology Exam 2 Questions With 100% Correct Answers

Macroevolution changes in a population over very long periods of time. Speciation the splitting of one species into two or more new species Biological Species Concept offers testable way to define a species that does not depend on appearance: The members of a species interbreed and have a shared gene pool, & each species is reproductively isolated from every other species. Gene flow occurs between the populations of a species, but not between pops of diff species. Biolo...

Species - group of individuals with the potential to interbreed and produce viable offspring *some asexual organisms are recognized as species although they do not breed. archaebacteria - microorganisms that are similar to bacteria in size and simplicity of structure, but radically different in molecular organization. now believed to constitute an ancient intermediate group between the bacteria and eukaryotes prokaryote - a single celled organism that has neither a distinct nucleus with a m...
