If a person receives blood transfusion that is not matching with their blood type, a reaction occurs that is linked to the antigens and antibodies not being able to exist in that environment. These types of reactions are described as "Type II Hypersensitivity".
Based on the scenario being described within the question it can be said that these types of reactions are best defined as type II hypersensitivity. This is an process in which specific antibodies bind to antigens that causes tissue damage or destruction, and mainly occurs when an individual is given the wrong blood type.
<span>I belive the answer is D. Burbank's process did not involve environmental pressures to shape the outcome.
Burbank process is similar to natural selection because he will select the potato based on some traits. The trait would be big potato and resistant to disease. The genetic makeup will also favor those with the selected trait. This process should be faster.</span>

antioxidant
cofactor in other enzymes
involved in wound healing (repair of tissue)
involved in the production of some neurotransmitters...
