A. MICROBES A group of bacteria that have a cell wall which is structurally more complex, contains less peptidoglycan and is often more toxic than the other group. A) Pathogen C) parasite B) gram negative D) gram positive A long, hair-like structure that grows out of a cell and enables the cell to move A) Mutualism flagellum B) Plasmids capsule A surface coating colony of prokaryotic that engage in metabolic cooperation A) Symbiosis pili B) Symbiont biofilms The small, circular segments of DNA that are found in bacteria and stay separate from the bacterial chromosomes; used in genetic engineering. A) Parasitism F plasmid B) Plasmids R plasmid A bacterial plasmid carrying genes that confer resistance to certain antibiotics. A) F plasmid C) R plasmid B) Nucleoid D) plasmids A fertility factor in bacteria; a DNA segment that confers the ability to form pili for conjugation and associated functions required for the transfer of DNA from donor to recipient. It may exist as a plasmid or be integrated into the bacterial chromosome.
A) F plasmid R plasmid B) F factor parasite The plasmid form of the F factor. A) F plasmid plasmids B) R plasmid nucleoid Respiration that does not require oxygen A) Endospores anaerobic respiration B) Parasitism heterocysts An animal or plant that nourishes and supports a parasite A) pili host B) symbiont capsule A protein-carbohydrate compound that makes the cell walls of bacteria rigid A) Peptidoglycan methanogens B) Endospores heterocysts Toxic substances made of lipids and carbohydrates associated with the outer membrane of gram-negative bacteria A) Methanogens C) exotoxins B) Endotoxins D) pathogens Toxic substances that bacteria secrete into their environment A) Biofilms endotoxins
B) Decomposers exotoxins A dense region of DNA in a prokaryotic cell. A) Pili symbiosis B) R plasmid nucleoid ________ allow prokaryotes to attach to surfaces and to each other and allow them to transfer DNA. A) Biofilms pili B) Host capsule The process of transferring genetic material from one cell to another by a plasmid or bacteriophage A) parasitism symbiont B) transduction nucleoid A sticky, gelatinous substance around the cell wall; allows cells to stick together or to the host cell A) endocapsule biofilms B) capsule flagellum Modification of a cell or bacterium by the uptake and incorporation of exogenous DNA A) Bioremediation conjugation B) Transformation gram positive A staining method that distinguishes between two different kinds of bacterial cell walls. A) gram positive gram negative B) gram stain parasite
Microbes that cause disease A) methanogens pathogens B) plasmids exotoxins Organisms that require a constant supply of oxygen in order to live A) Photoheterotrophy C) Obligate anaerobes B) Obligate aerobes D) Pathogens Organisms that cannot live where molecular oxygen is present A) Conjugation C) Obligate anaerobes B) Obligate aerobes D) Facultative anaerobes The relation between two different kinds of organisms in which one receives benefits from the other by causing damage to it (usually not fatal damage) A) parasite C) pili B. parasitism D) mutualism What is the fundamental tool in immunofluorescence testing? A) Specific antigen D) Red blood cells B) Complement D) Fluorescent monoclonal antibody C) Fluorescent polyclonal antibody HIV targets include all of the following except A) macrophages. C) B cells B) cytotoxic T cells. D) helper T cells.
