    Hey Dr. Kerschen, I have read that probiotics are ultimately ineffective because the types of uncapsulated bacteria that are used in yogurt and such are destroyed in the stomach, mouth or esophagus before they can reach the small intestine. Could you shed a little light on this?

    I’m not afraid to say that the growth rate of bacteria may reflect the rate at which human souls descend to hell. Feasibly, population could reach an equilibrium with the ecosystem. Is that not the Christian answer? I can also imagine a world in which everyone agrees with Ben Shapiro that to remain celibate is essentially selfishness. With the same demand, I justify myself even knowing that I commit to this selfish action. They will go to hell in my place.

    Is there a way to get practice tests for these lectures? Your lectures line up w mine perfectly but are so much easier to understand. My professor is super old school and all our tests are fill in the blank w genus and species I’ve never even heard of and can’t even pronounce especially spell- would be so appreciated!!

    Why do psychrophiles make us sick after we eat them if our body temperature is above their maximum temperature?

  14. Argonaut on November 1, 2020 at 11:34 pm

    I suppose you are a little mistaken about life. Indeed a microcurents and self induced magnetic microreactions provide energy and radiation spectra. Marine life deep in Oceans, where no light and no photosynthesis does exist.

    Hi Dear Professor. Thanks so much for your help. Sometimes we are talking about the electron source, which led to some confusion, as electrons come also from carbon sources. ANy explanation of that point please ? Thanks

    You are singlehandedly getting me through micro with all these video. Thank you!!! Online Covid Micro is awful!!!

  20. Mich on November 1, 2020 at 11:49 pm

    My prof just threw 8 chapters in 2 lectures for Micro. I have not taken chem, bio in over 8 years, Every time I tried taking notes in class she’d be on the next subject and I was so confused, overwhelmed, and upset. You have helped TREMENDOUSLY. You don’t talk to fast and break it down like you should to make the subject easy, fun, and not as overwhelming. THANK YOU SO MUCH we need more teachers like you. You have no idea…
