<h2> Ecological Footprint</h2>
The ecological footprint is an indicator that accounts for human demand on global biological resources. If a person observed his ecological footprint, there will be less environmental problems like carbon emissions, lack of fresh air, global warming and increased environmental pollution would be reduced.

Gel electrophoresis is a method of genetic analysis which involves seperating segments of DNA based on their size and charge.
It involves cutting DNA with various enzymes, then placing the DNA in an agarose gel. An electrical current is then run through the gel. Because DNA is a polar molecule the DNA segments will travel through the agarose cell as the current is applied. Larger fragments will travel shorter distances than shorter fragments. Two plates with 2 different DNA samples will be conducted and the orientation of the DNA strands will be used to make an analysis by comparing the 2 plates.
c. It never changes during the experiment.
