Which step of Koch's postulates is incorrect?
1.The pathogen is first found in an infected, unhealthy
person.
B. 2.The pathogen is isolated from an unhealthy person
and grown in a lab.
C. 3.The pathogen grown in a lab will be given to a healthy
organism that gets the same disease.
D. 4.The pathogen should be isolated again and should
have mutated when compared to the original.

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).

i do believe the correct answer would be the third one. location c, because earth is tilted away from the sun at this time

hope this
