This is because gold is very resistant to bacteria. Bacteria are microscopic single-celled organisms. Bacteria are prokaryotes‚ meaning the entire organism consists of a single cell with a simple internal structure. The DNA of a prokaryote is neatly packed in the nucleus. The bacterial DNA floats freely in a twisted threadlike mass called the nucleoid. Gold is unaffected by almost everything. The only materials that can affect gold are man-made. Since bacteria are a natural organism‚ it cannot react

a. The bacteria that causes botulism are found in soil‚ water‚ animal guts and dung. When the spores exposed to low oxygen and certain temperature‚ they produce botulinum toxin‚ able to germinate‚ metabolize‚ food sources through an aerobic respiration to produce toxin. The toxin blocks the release of acetylcholine from motor nerve endings causing paralysis symptoms. The botulism either food born‚ eating contaminated home-canned foods where the fermentation takes place. or through abrasion in the
