g Let's investigate how protons can rock hemoglobin's world. Place a negative clay blob at F, and a special PINK blob (also negative) at G representing a HISTIDINE. On their own, they don't come together, and certainly don't contribute to the -releasing (conformation). However, if there were lots of protons around, also called ions (represented as positive clay), do you think the negative pink site would be a welcoming location for the protons to 'stick to'

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).
