Linnaeus lived hundreds of years before scientists discovered DNA, genes, and the roles of DNA and genes in determining the trai
ts of organisms. How have discoveries about DNA and genes affected scientific classification? A. The discoveries confirmed all of the classifications that Linnaeus proposed, and no revisions have been necessary.
B. The discoveries confirmed all of the classifications that were based on observable traits, and no revisions have been necessary.
C. Although the discoveries did not confirm some of the classifications that were based on observable traits, scientists did not revise the older classifications.
D. The discoveries confirmed many but not all of the classifications that were based on observable traits, and scientists revised classifications when necessary.
D. The discoveries confirmed many but not all of the classifications that were based on observable traits, and scientists revised classifications when necessary.
I believe the correct answer would be B. Semipermeable means that it allows certain substances to pass through, and certain other ones to not pass through. So given all of your options, I would say that B makes the most sense. Hope this helped!
