Suppose you wish to test a species of bacteria to see if it will grow under anaerobic conditions. You know that this species grows best at high temperatures and acidic pH. It does not grow well at low temperatures and alkaline pH. Describe your experimental setup.

Your team suggests changing the temperature of the oil spill site in order to enhance the bioremediation process. Do you consider this decision effective? Why and why not? Explain, in your answer, the effect of changing the zone tension on the homeostasis capacity of the bacteria you use and their ability to withstand the osmotic pressure of the new surrounding solvent. In your answer, state how osmosis works and state the degree of tension of the solution (isotonic, hypertonic or hypotonic). Explain why osmosis is really just a special case of facilitated diffusion

Practice Question #2 Each of the following statement FALSE. Tell me what is incorrect with the statement and correct it when possible. For example, if the statement says: the sky is red during daytime. You would answer: the sky isn't red during daytime, it is blue. a) Your lab supervisor asks you to grow a new bacterium they got from a collaborator. You grow them in the suggested nutrient-rich media, and you notice that as the log phase growth progresses, the bacteria seem to turn purple. You mention it to your supervisor and ask whether it is the gradient from very high to low nutrient bioavailability that induces metabolic changes which induces the production of a purple pigment. Your supervisor tells you that is unlikely. What is a more plausible conclusion? Note: The metabolic changes statement is wrong, the "plausible conclusion" is this case is the correction of the false statement, conclusion. the more plausible b) The organism in Tube B is microaerophilic. Oxic zone Anoxic zone…

Scientists have discovered a new strain of bacteria but do not know its morphology. They have also discovered that this bacteria is not heat sensitive but its morphology is heat sensitive. How will you observe the morphology of this bacteria. Give supporting reason for your strategy
