The Savannah (A) is a hybrid domestic cat breed. It is the result of selectively breeding domestic cats with African servals (B) in order to produce the signature color markings and large size. Not all, but many of these Savannah cats are able to successfully reproduce with other domestic cats.

What could be a long-term effect of this type of artificial selection by humans?

for example: Dog breeding is another prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.

Explanation:

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
