Aspecies of birds entered a non native habitat and is now considered an invasive species. what’s the most likely effect this species will have on native species that share the same resources?

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate

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).
