What type of organism did the enzyme taq polymerase come from?

Explanation:

Taq polymerase is a heat-stable DNA polymerase , an enzyme, and it comes from the thermophilic bacterium, which inhabits hot springs and hot areas.

It was originally isolated from thermophilic bacterium and  was named as Thermus aquaticus (T. aquaticus)

This enzyme is heat stable and do to denature easily.

Taq polymerase is very usefull in PCR. Through PCR we can make large number of DNA from a small sample in a very short time.

i am going to guess that it is co2.

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).
