The impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources. That is for the first question
The cell membranes begin to come apart when there is insufficient water around the cells. The cytoplasm of the cells becomes more concentrated, which slowly poisons the cells. The cell walls become brittle as they dry out, and some of them collapse. The central vacuoles in the cells lose water and can no longer help support the cells.

The correct answer among the choices provided is option C. Water helps to maintain the structure, flexibility and motion of proteins. Hydration makes the protein structure more packed and stabilized. It is because water is included in many networks of hydrogen bonds.
Answer:
Plastic and trash bags can be used to generate renewable energy in the following way the mechanism of cold plasma pyrolysis.
Explanation:
- Cold plasma pyrolysis is a method in which chemical compounds like plastic wastes and trash bags are subjected to high temperatures like 400 to 650 degree Celsius under limited oxygen condition.
- The above process generates huge amount of energy in the form of heat that can be converted to usable electricity.
- The process generates compounds like hydrogen, methane and ethylene.
- The hydrogen and methane can be used as clean fuels because they produce minimum harmful components like carbon dioxide and soot on combustion.
- The ethylene is the basic component of plastics and can be reused to produce more plastics.
