1. Deep sea thermal vents are characterized by extremepressures, very high water temp (exceeding 100 celsius) and veryhigh concentrations of minerals. What type of prokaryotic organismsare most likely to be found there and why?
Archaea; tetraethers are morethermally stable. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Archaea; the partial membranessurrounding the DNA provide more protection. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Bacteria; the peptidoglycans in thecell walls keep them from overheating. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Bacteria; they use the energy from the minerals to power theirchloroplasts. 2. Farmers often practice crop rotation to help enrichagricultural fields. Why are beans and other legumes often used inthe rotations?
