…in the air. Yoghurt contains microbes devoid of any being provided from the air. 14)<Tab/> It is completely essential/ obligatory to use sterile techniques when dealing with bacteria, microbes and micro-organisms to guarantee there is no infectivity from other microbes situated somewhere else. This ensures a higher percentage of accuracy within the results CONCLUSION: We managed to observe sterile techniques while also observing macroscopic microorganisms in food, water and the air
