Biofuels are derived from crops and plants. The two most popular types of biofuels are biodiesel and bioethanol. There are many pros and cons of using biofuel. The best reason why you should use biofuel is to reduce pollution. This type of fuel releases lesser amount of carbon dioxide. However, unlike conventional types of fuel, it is expensive to produce biofuel, which is primarily caused by the low investment put into the development of biofuel in the market. If there is enough funding, it would be worth it to put up a biodiesel power plant.
Answer:
Natural selection
Explanation:
Natural selection is a process where some organisms are able to reproduce more and survive better due to the presence of beneficial genetic traits in them. The other organisms of the same population that lack these traits are not able to survive and reproduce in the same way. The bacterial having drug resistance are able to survive in the presence of drugs in the surroundings. These bacteria will reproduce more and leave more progeny. Over the generations, the proportion of the bacteria with drug resistance will increase. This represents an example of natural selection.
