Question 1 What is the difference between a pure culture and a mixed culture? Pure cultures contain a single species. Mixed cultures contain two or more species. Pure cultures contain at least two species. Mixed cultures contain four or more species. Nothing these terms are interchangeable. Pure cultures contain two or more species. Mixed cultures contain a single species. Question 2 When you transfer something aseptically, what are you taking care to do? Not to contaminate the environment. Not to contaminate others around you. All answers are correct. O Not to contaminate yourself. Question 3 Why would you grow organisms in broth media? Broths are used when fresh cultures or large numbers of microbes are needed. Broths are used when you want to identify a species. Broths are used for colony morphology studies. Broths are used to grow stock cultures that can be refrigerated and maintained for several weeks.

What is the difference between a probiotic and prebiotic? Group of answer choices Prebiotics are natural chemicals present in food, whereas probiotics are artificial chemicals added to food to improve their nutritional value Prebiotics are living microbes that transform food, whereas probiotics are microbes grown in the lab and added to food.

Question 3 Should viruses be considered living organisms or abiotic structures? Give three reasons used to support the viewpoint you choose. Narrate the journey of a guanine molecule that ends up as part of a viral capsid. Be specific about the setting. Imagine that you are observing a population of bacterial cells that are infected by a virus. You determine that an enveloped virus is responsible. You take a sample of host cells and immediately lyse (break open) these cells. Why would this sample be harmless even if added to media and mixed with fresh host cells?
