If it turns out that the whale lineage diverged from the lineage leading to hippos after the divergence of the lineage leading to the pigs and other artiodactyls, and if the whales continue to be classified in the order cetacea, then what becomes true of the order artiodactyla?

It becomes paraphyletic

Explanation:

Any community of species given a formally taxonomic title is a taxon (pl. taxa). Broadly, a monophyletic taxon contains an organism community from a common ancestor, while a multifyletic taxon consists of unconnected organisms from more than one forefather.

The broad meaning of fish, for example, is one of those concepts that include mammals including whales, and also sharks, salmon or scaled shrimp, of which ancestral vertebrates are often the common relatives, through which amphibians and reptiles come.

Referencing a group of species as a paraphyletic group means that some biological group members have also been positioned in another group for whatever reason.

can you explain a little further maybe give multiple choice? ?

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
