Water drops that fall on a smooth surface tend to form rounded drops or beads. Then, if you touch a piece of paper to the drop, water appears to move up into the paper on its own. Identify and describe the properties of water that explain this phenomenon

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).
