Do not just click on the answers and write them out. This will not test your understanding of this tutorial.

1. Matching

_____ Bacteria that grow best at moderate temperatures. Their optimum growth temperature is between 25C and 45C. (ans)

_____ Cold-loving bacteria. Their optimum growth temperature is between -5C and 15C. They are usually found in the Arctic and Antarctic regions and in streams fed by glaciers. (ans)

_____ Organisms that grow with or without oxygen, but generally better with oxygen. (ans)

_____ Organisms that grow only in the absense of oxygen and, in fact, are often inhibited or killed by its presense. (ans)

_____ An environment where the water concentration is greater outside the cell and the solute concentration is higher inside. Water goes into the cell. (ans)

_____ Organisms that use the oxidation and reduction of chemical compounds as their primary energy source. (ans)

_____ Organisms that use light as an energy source and carbon dioxide as their main carbon source. (ans)

_____ Organisms that use organic compounds as both an energy source and a carbon source. (ans)

_____ Organisms that use light as an energy source but cannot convert carbon dioxide into energy. Instead they use organic compounds as a carbon source. (ans)
