Which of the following is NOT true of bacteria?
a. Bacteria change the sugar in milk to lactic acid.
b. Bacteria change nitrogen into a form plants can use.
c. Bacteria change harmful chemicals into harmless ones.
d. Bacteria change oxygen into nitrogen.
a. Bacteria change the sugar in milk to lactic acid. Is true Fermentation.
b. Bacteria change nitrogen into a form plants can use. True nitrogen fixation
c. Bacteria change harmful chemicals into harmless ones. True Bioremediation
d. Bacteria change oxygen into nitrogen. True nitrogen fixation
so what then? because these are the only answers on my test
D is not nitrogen fixation, but the nitrogen cycle. You may have to email your teacher, but google each one and double check what I told you. However, if I had to pick one, I would pick c, because when bacteria are used form bioremedation, they are engineered or bread to do this, but they can be used to turn harmful chemicals into harmless ones, so it is true.
I halfway read the question. The answer would be D. They combine oxygen with nitrogen to make NO, but they do not turn it into N from O.
