Microbe - Answer-A living thing that is too small to be seen by the naked eye; require a microscope to see them; includes many different life forms including bacteria, archea (often live in extreme environments), fungi, protists, viruses, and microscopic animals Microbiome - Answer-The totality of microbes, their genetic information, and the milieu in which they interact; typically consist of environmental or biological niches containing complex communities of microbes; including gut and to...

Microbiology Chapter 4 UTA Tholen Latest Update Graded A+ Prokaryotes (Bacteria and Archaea) are everywhere. Prokaryotes are VERY adaptable & resilient Prokaryotes have the ability to switch metabolic or respiration methods Mutualism both populations benefit; ex: gut nutrition metabolism Amensalism one population is harmed and the other is unaffected; ex: antimicrobial defense on skin Commensalism one population is benefitted and the other is unaffected; ex: Skin cells as ...

Brooks Biodiversity Unit 2 Exam with Certified Solutions The Primary role of Fungi Decomposers- they break things down Modes of Nutrition in Fungi Heterotrophs with extracellular digestion Exoenzymes Fungi Release these enzymes outside of the cell wall. Break down complex molecules into smaller organic molecules which can be absorbed. Extracellular Digestion The release of exoenzymes out side of the cell wall, followed by the absorption of nutrients.. Saprobes Fungi that feed...

Species evenness is an important measure of diversity in an ecosystem. T/F correct answer: true When a tapeworm steals nutrients from the gut of a mammalian host, that symbiosis is called: intraspecific competition. parasitism. commensalism. mutualism. predation. correct answer: parasitism Based upon the age structure diagram, you expect the American population to: grow because all of the age classes have roughly equal proportions of people. grow then shrink because many of th...

prevents microbes from entering the ear. - What is the function of earwax? Pathology: - the study of disease. Etiology: - the cause of a disease. Pathogenesis: - the development of disease. Infection: - invasion or colonization of the body by pathogens. Disease: - an abnormal state in which the body is not performing normal functions. Normal microbiota: - permanently colonize the host and do not cause disease under normal conditions. Transient microbiota: - may be present for days, weeks...
