Because of high increases in populations, some underdeveloped countries are already exceeding their carrying capacity. They cannot produce enough food to support their populations. These regions are undergoing very rapid desert formation. Growing populations contribute to this by clearing forests for agriculture and firewood. Which region in the table is most likely experiencing desert formation?

it would be rhyolitic hope this

chert is a sedimentary rock composed of microcrystalline or cryptocrystalline silica. with this little bit of information, you can come to the conclusion that your answer is c.  

explanation:

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
