Food is often preserved by the addition of salts and/or sugars or by drying (e.g., dried fruit, beef jerky, etc.) Similarly, many products (e.g., crackers, biscuits, cookies, chips etc.) have a long shelf life simply by being dry even if they may or may not have a high sugar or salt concentration. Please explain how these approaches work to prevent microbial growth on these food items; specifically, and using scientific terminology you have learned, explain the impact these approaches have on microorganisms.
