- One of the types of structures on this list is NOT part of the reproductive cycle of a microbe. Identify that one. bacterial spores fungal spores yeast buds protozoal cystsDefine the following terms:a. endotoxinb. periplasmic spacec. biofilmd. slime layere. bacterial capsuleAnswer all of the following true or false questions: True / False: Choose the answer that best fits each statement. The presence of Escherichia coli in water is used as an indication of fecal contamination. The Vibrio species are characterized as being curved, gram negative bacteria with polar flagella. Chlamydia, Rickettsia and Mycoplasma are all obligate intracellular parasites. Neisseria, Staphylococcus, and Streptococcus are all gram-positive cocci. Tetanus, botulism, and diphtheria are diseases caused by gram positive, soil-dwelling, spore- forming rods. Most togaviruses are transmitted to humans via insect bites. The reason why dogs do not get measles is because their cells lack the correct receptor sites for that virus. Glycoprotein spikes are found on the capsids of viruses. A naked virus lacks a capsid. The polioviruses and hepatitis A virus are transmitted by contaminated food or water. Staphylococcus grows best in a high salt environment.…
