Document Summary
What is the most common method of preserving household food supplies? refrigeration. What is the optimum growth temperature for mesophiles. Also known as extreme thermophiles that survive at temperatures of 80 degrees celsius or higher ph. Refers to the acidity or alkalinity of a solution. What is the optimum range for ph for growth of bacteria. Shrinkage of a cell"s cytoplasm due to a hypertonic solution. Organisms that have adapted to high salt concentrations. Organisms that require high salt concentrations in order to survive. Organisms that do not require high salt concentrations but can tolerate salt concentrations at 2 percent. Structural backbone of living water and the food source for most organisms. Nitrogen and sulfur are required for protein synthesis. The use of gaseous nitrogen directly from the air for photosynthesis. Organic compounds necessary for growth that tend to be obtained from the environment.
