  1. Long story short, I did a bio extended essay, messed up the experiment, instead of isolated colonies I got a single weird blob. No data collected. Failed the experiment. Am I allowed to use external data to support my arguments?
  2. So I decided that for my extended essay, I was gonna culture bacteria (e.coli) and check the effect of the pH and the correlation between the pH level and the growth of the bacteria. However, instead of using the quadrant method to spread the bacteria over the plate I just made a continuous pattern as seen in the pic. Can somebody help me count the colonies to check how the pH affected the growth? Thanks, plenty.
  3. I would like to ask you guys about my extended essay topic, and honestly, tell me if it's fine. Can we successfully genetically engineer E.coli bacteria to fix nitrogen?. As the title suggests, I would chemically engineer e.coli bacteria to go through the process of natural nitrogen fixation. Concerning tools, I got in contact with a university nearby and they agreed to help. Am sorry if this sounds like it was written in a hurry because... well.. it was.
  4. extended essay

    Thanks for the feedback! So ... Can I ask you what you think would be a good topic that will involve the use of acid base titration? How do you think I can twist that to a biology extended essay
