Answer:
a-The HIV patient
Step-by-step explanation:
Choices b, c , and d are all isolated. If A is not correct then it would have to be choice b. HIV is more apt to evolving to a single persons immune system as well as any medication that may be in the immune system. The rose bush may be able to adapt due to potential cross pollination. The cat at home will not be bale to evelove becasue it says " INDIVIDUAL cats in a home" Cats need the mate to reprode, a single cat can not reprodce which makes it the worng answer choice. Choice d is wrong becasue the bacteria is asexual. It procreates and reproduces on its own. There is no genetic variation, keeping it the same. Hope my choices help..
