Impact of the use of fossil fuels during the industrial revolution was it made possible a huge increase in the amount of productive energy available to humans.
The development of machines, including steam engines and the internal combustion engine, made it possible to exploit vast new resources of energy stored in fossil fuels, specifically coal and oil. The fossil fuels revolution greatly increased the energy available to human societies during industrial revolution.
Contrary to this fossil fuel have some disadvantages like when fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.

means lethal dose. LD50 is the amount of a material, administered at once to
cause the death of half (50%) of a group of test organisms. A test which shows that LD50 of a certain
chemical is 20 mg per kg means that 20 milligrams of that chemical for every 1
kilogram body weight of the test animal when administered in one dose, causes
the death of 50% of the test group.</span>
In the Hardy-Weinberg principle, the values of p and q will not change if evolution is not occurring.
<h3>What is the Hardy-Weinberg principle?</h3>
The Hardy-Weinberg principle is a model used in population genetics to estimate genotypic and allele frequencies in a population.
The Hardy-Weinberg principle states that allele and genotypic frequencies remain constant in absence of evolutionary forces.
These evolutionary forces include nonrandom mating, gene drift, gene flow, mutation and natural selection.
