1. Proper aseptic technique is crucial to ensuring growth of pure bacterial colonies. What is one experimental way you can test your practices to confirm that you are using proper aseptic technique? One experimental way to test if you are practicing correct aseptic technique would be to create a control petri dish or stab tube. Monitor the control dish or tube regularly over the next few days to see if any bacterial colonies have grown. If you do see colonies growing, then proper aseptic te...

1. What determines if a bacterial cell is Gram-positive or Gram-negative? Gram-negative bacteria are surrounded by a thin cell wall, while gram-positive bacteria lack a cell wall. 2. In this lab, both viruses and prions were introduced as acellular organisms. Do some research and describe one other type of acellular organism. What characteristics about this organism classify it as acellular? Another example of an acellular organism would be viroids. Viroids are small, single- stranded, cir...

1. What constitutes personal protective equipment? When should personal protective equipment be worn? Why is personal protective equipment important? Personal protective equipment Includes: safety goggles, face protection, gloves, aprons, lab coats and shoe covers. PPE should be worn whenever an experiment is being conducted and whenever an airborne pathogen or contaminant can be transferred to you. It is important to use PPE in order to protect yourself from harsh chemicals and viruses. P...

1. What is the difference between chemically defined and chemically complex media? Give either a clinical or environmental research example for which each media type would be the most appropriate choice for culturing microorganisms. The key difference between chemically defined and chemically complex media are their compositions. Chemically defined media is made up of all known compositions. While, chemically complex media is made up of unknown compositions (which can vary from batch to bat...
