Why are rainforests particularly vulnerable to environmental degradation from subsistence farmers ? A. Because their live hoods depend on feeding their families with the food they grow, which requires fertile land that can be acquired by cutting down the forest and burning the brush.

B. Because farmers supplements their diets by hunting large, edible species, which drive some to extension.

C. Because governments are clearing land For agriculture on an industrial scale

D. Because as farmers move to urban areas, vast tracts of land They once occupied are purchased for logging by international corporations.

Please help would be really useful , thank you!

Taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? view available hint(s)taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? the enzyme will not work on human dna.nothing should be altered.the ph should be decreased.the temperature should be raised.
