1. In order to procure fossil fuels, or even to burn them, we create a great deal of pollution. All of the pollution that is being created is extremely bad for the Earth because it contributed to global warming.
2. When we create new mining cites, we remove trees and soil that was once the home to plant, animal, and insect life.
3. Oil is a very useful fossil fuel, it is used to power many things. But due to the very dangerous nature of fossil fuels, an explosion in Mexico in 2010 caused 210,000,000 U.S. gallons of oil to spill into a gulf. This spill lead to the drowning and poisoning of immeasurable amounts of aquatic animal life.
Answer: Genetic variation describes naturally occurring genetic differences among individuals of the same species. Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation. And there are the reasons.
Haploid cells! Hope this helps :)
Diploid refers to a cell that has two copies of each chromosome. One way that a diploid organism could have an offspring that are 3n (triploid) or 4n is when the chromosomes don't separate during meiosis.
Triploid refers to some cell that have 3 copies of each chromosomes for a total of 69 chromosomes.
