    That's not fair. That info is not in the text

    That is exactly what I thought too. I can't really blame the teacher because the question was written by the author. Now that I asked her about I hope she goes over it in class. I feel good about the other questions. I do have to admit that after all that AP the critical thinking questions are a bit of a challenge. And probably good to work on in case I do make it into a nursing program. I hope I hope I hope. :spin:

    Did you have to do any of the questions at the end of chapter 2 (chemistry, Tortora)? I am stumped on critical thinking question #3. "What happens to the relative amount of unsaturated lipids in its plasma membrane when E.coli grown at 25c are grown at 37c degrees?" aren't unsaturated lipids fluid at both temps and why would the amount chance? I am missing something.
    the relative amount of the unsaturated lipids in the membrane should not change when e.coli are grown at 25 or 37 Celsius because the lipid inside the membrane is as viscous as olive oil which won't get too fluid when warmed or too thick when cooled......the consistency stays the same even though there is a temp difference. However, as far as I know e,coli loooove 37 degree body temp and function best at that temp because their job is to hang out in your large intestine and wait for all that undigested food leaving the small intestine. They are called enteric bacteria. Ecoli do what they love best at 37....attack the undigested food particles from vegetables etc and ferment these which will give you all that nasty gas Please check with your instructor on this one

    Don't know if it's right....I am sure some really smart student/ graduate will set it straight if I am wrong

    I'm taking micro-bio this semester as well. Very much so excited this is my last semester of prereqs. Does anyone know of any good study websites?

    We had our first lecture today and I think it is going to be a really good class. :spin: It sparked my interest.

    also your text book might have a website, mine came with a cd or you can use the online version. they are so helpful.

    my book although was expensive came with a study guide and the computer cd, i like to have lots of tools.

    My teacher's pretty weird. Lectures wild and made the mistake of giving carbon an atomic number of 12 rather than 6. A fellow student had to correct him *lol*

    Obviously, we're on the chemistry chapter.

    I can't wait to grow some cultures.

    Good luck with your scattered professor

    I had my first Micro class yesterday...and I like my teacher...she is straightforward.
