Circle. What is the charge of electrons? Positive Negative

I think there positive negative because you can't have an eletrical charge with out a pos or negative

the correct answer to this question is #5

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).
