Answer:
Renewable resources cannot disappear, non-renewables will not last forever. Non-renewable energy sources, such as coal, nuclear power, oil, and natural gas, are available in limited quantities. 
Explanation:
A renewable resource, for example, is solar energy. It is renewable because the sun can never disappear. 
Non-renewable resources take a long time to replenish, if this ever happens. Renewable resources naturally recharge over a relatively short period. Non-renewable resources are natural resources that exist in fixed quantities and can be utilized. Examples include fossil fuels such as oil, coal and natural gas.
Both types of resources have a big influence on biodiversity and people shouldn't be spending them without limit.

b. the use of DNA as the information storage molecule
Explanation:
Prokaryotic cells are the ones that lack the membrane-bound organelles and well-defined nucleus. Eukaryotic cells have the nucleus and other membrane-bound organelles. Most of the prokaryotic cells are smaller in size as compared to eukaryotic cells. Despite these differences, both prokaryotic and eukaryotic cells have DNA as their genetic material. DNA serves to store genetic information in both types of cells.
