the following bacteria is either helpful or harmful. determine which and why: Streptomyces, staphylococcus, and rhizobium Streptomyces: help; it is a bacteria that produces more than 1/2 of our antibodies staphylococcus: harm; it is puss and is a toxin if you eat it rhizobium: help; it has the ability to be nitrogen fixed and is good for soil so farmers like this
explain how gram positive and gram negative bacteria are constructed and how it relates to the way they stain. gram positive:peptidoglycan – color purple: cell wall contains large amounts of peptidoglycans wall retains the purple die so they are purple gram negative:little peptidoglycan – color pink: very thin wall don’t retain purple die therefore appear pink
gram positive and gram negative; relate how this determines which antibiotics are effective against them, list examples gram positive: Penicillin: a antibiotic that kills gram-positive organisms by preventing the proper formation of the peptedcilen cell wall gram negative :Tetracycline: a antibiotic and gram negatives are also suseptical to this
list and describe the 3 methods that bacteria can obtain energy. Photosynthetic: autotrophs and obtain energy through the sunlight Chemoautotrophs: obtain energy by removing electrons from inorganic molecules such as ammonia or hydrogen sulfide Heterotrophic: feed on organic material formed by other organisms
give examples where applicable for chemoautotroph and heterotrophic Chemoautotrophs: ex: Nitrosomonas and Nitrobacter – do the process of nitrification heterotrophic: decomposers
