Answer:
A. is the answer
Explanation:
Oil, coal and natural gas resources are non renewable energy sources.
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time. Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation. Often cells can recognize any potentially mutation-causing damage and repair it before it becomes a fixed mutation.
Mutations contribute to genetic variation within species. Mutations can also be inherited, particularly if they have a positive effect. For example, the disorder sickle cell anaemia is caused by a mutation in the gene that instructs the building of a protein called hemoglobin. This causes the red blood cells to become an abnormal, rigid, sickle shape. However, in African populations, having this mutation also protects against malaria.
However, mutation can also disrupt normal gene activity and cause diseases, like cancer. Cancer is the most common human genetic disease; it is caused by mutations occurring in a number of growth-controlling genes. Sometimes faulty, cancer-causing genes can exist from birth, increasing a person’s chance of getting cancer.
One possible negative side effect of planting corn that is resistant to weed-killer is that: the resistance gene could be transferred to actual weeds, making farming more difficult.
<h3>What is genetic engineering?</h3>
Genetic engineering is also referred to as genetic modification and it can be defined as a technological process that involves the use of laboratory-based technologies to alter or modify the deoxyribonucleic acid (DNA) makeup of a living organism, in order to improve on both its physical and chemical conditions, or cure (correct) a genetic disorder in some cases.
Based on historical records, corn is a genetically modified crop with an ability to resist weed-killer, which makes it possible for it survive even when it is exposed to herbicide that are designed and developed to kill weeds.
However, one of the demerits of planting a genetically modified corn that is resistant to weed-killer is that the genes responsible for this resistance could be transferred to actual weeds, which would eventually make farming to be more difficult for farmers.

I believe wilderness, but you can go online and research it just to make sure !
