Endospores are     a) resistant to extreme temperatures     b) produced by some prokaryotes     c) can survive for decades     d) all of the above

Why is it favorable for protozoa to replicate with schizogony versus using simple mitosis? what are the different scenarios that can occur with regards to bacterial growth within a thioglycolate tube? Explain why certain bacteria require one classification versus a different classification. A botanist has been using betaproteobacteria to grow his herb garden, because betaproteobacteria require little nutrients to grow. His garden does not grow successfully, so he comes to you for help to develop the herb garden.  Which class of gram negative bacteria would you suggest and why?  Why was the botanist’s original idea not going to work?

Most bacteria require a water activity of 0.9 or higher to grow. A prolonged period of being dry usually causes loss of viability. How were there still living bacteria in many of the dried foods such as dried rice, dehydrated coconut flakes, raisins, etc.? Discuss.

9. Certain bacteria and archaea, such as methanogens, and deep-sea vent bacteria uses inorganic chemicals and makes organic compounds using CO2. These are called -----------------.  a) Chemoautotrophb) organotrophs c) inorganothrophsd) lithotrophse) phototrophs
