As the human population increases, stressors are being placed on the environment. <u>Decreases in availability of </u><u>natural resources</u> is one consequence of this growth.
Population- A population is the total number all organisms belonging to the identical species that really are present in a given location at the same time and have the potential to interbreed. Individuals need to be able which can mate with other members of a population and give birth to viable children for interbreeding to take place.
Natural Resources- Without human assistance, natural resources are present on planet. We can get water, wood, food, and energy from natural resources. Without natural resources, life is not conceivable. Oil, coal, natural gas, metals, stone, and sand are examples of natural resources.

Answer:
DNA is negatively charged. When an electrical current is passed through a gel, the DNA is repelled by the nearby negative current and pushed across the gel towards the positively charged side.
Explanation:
Electrophoresis has become a standard molecular biology technique. This technique is based on the use of a constant-uniform electric field that enables the separation and identification of DNA fragments with different lengths, which form bands in the electrophoresis gel. Electrophoresis can be used to analyze not only DNA, but also RNA and proteins. During electrophoresis, the fragments of DNA that are negatively charged will migrate towards the positively charged electrode, where the duration of this movement will depend on the size of the DNA fragment, as well as of the pore size in the gel.
