What are they used for?Describe the industrial uses of Dunaliella?Describe what issues cell harvesting presents on an industrial scale.Explain what stress proteins are and how they are related to the ability of cells to live in extreme environments.

Explain what is happening with this graph that charts the reactions ofa mesophilic bacterium to temperature. Blue shows the survival curveand brown the growth curve under various temperatures.

What do you think is more influential on the types of bacteria or other microorganisms that are involved in biofilm formation – the physical environment or the solid substrate on which it forms? Why?

Circle/highlight either T or F for each row T T T T T T F Mechanosensation is the way we sense all temperature LL F F LL F ןד FL Axons need a growth factor in order to grow Secondary active transport is when a solute moves against its gradient and that movement is powered by ATP You can couple passive transport with active transport in order to move a solute against its gradient Thermal vents were the likely the source of energy for the origin of life F Neurons that innervate the limb are never born if the limb isn't there

Pseudomonas aeruginosa is capable of aerobic respiration and anaerobic respiration but not fermentation. It can produce H2Sdoes not produce tryptophanase, and is motile by a flagellum . Based on the above characteristics, describe your expected results for Pseudomonas aeruginosa in a SIM deep .

Why can’t larger multicellular organisms live in the same places as these archaeans?

Escherichia coli O157:H7 is a foodborne pathogen and can cause serious illness in humans by producing toxins that can severely damage the lining of intestines and kidneys. What are the oxygen requirements of coli? What result would you observe in the MTM agar deep test? Explain. Research on the growth requirements of this bacterium is required. What is the role of oxygen and cytochrome c oxidase in aerobic respiration? Why does the nitrate reduction tube turn red after the addition of zinc? Clostridium tetani is a common soil bacterium and causes tetanus. Would you expect tetani to possess the enzyme catalase? Explain. Research on the growth requirements of this bacterium is required.

Single celled organisms that grow in irregular masses and include molds mildews and yeasts? How does an abundance of tryptophan inhibit the production of more tryptophan?
