conductor like a wire‚ a current of electrons will flow in the wire from the anode to the cathode. Inside the solution‚ positively charged ions from the oxidizing metal will migrate to the other metal‚ where they will again receive electrons and plate that metal. Lemon Cell While there are many electrolytes which will cause this reaction‚ citric acid is frequently used as a demonstration because it occurs naturally in citrus fruits. The two metals often used are zinc‚ as in a galvanized nail‚ for

Introduction It is crucial in the field of microbiology to study the morphology‚ biological activity‚ and the behavior of microbes thus the isolation of such microbes from the environment is necessary because it allows scientists to study them in close proximity. Microbial life forms are found everywhere. They are major players in biogeochemical cycling of elements and primary producers in numerous environments. There are also some microbes living inside higher forms of organisms that aid in digestion
