Trava [24]3 years ago

Answer:

D

Explanation:

When lead ions and sulfate ions bond, they form sediment so neither a nor b can be the answer.

The important thing is that two nitrate ions were originally bonded with one lead ion, while two potassium ions bonded with a sulfate ion.

Finally, since potassium and nitrate ions don't form sediment these two ions must remain. Therefore the answer is D

Which line of evidence has been traditionally accepted as conclusive proof of evolution? the presumed age of the Earth the fossi
Nataly_w [17]

The most generally accepted form of conclusive evidence for the theory of Evolution is the fossil record.

<h3>What is the theory of Evolution?</h3>
  • The theory of evolution was proposed by Charles Darwin.
  • It states that as time passes, organisms evolve to better adapt to their environments.
  • This is closely related to natural selection, which is considered a <em><u>driving force of </u></em><em><u>evolution</u></em><em><u>. </u></em>

<h3>How the fossil record supports this theory</h3>
  • The fossil record provides essential data to support this claim.
  • The data comes in the form of the comparison between fossils of two closely related organisms, separated by a matter of generations, that <em><u>present changes in the genetic code that made them more apt for survival.</u></em>

Therefore, we can confirm that the most generally accepted form of conclusive evidence for evolution is the presence of <u>fossils </u><u>that show the genetic correlation between two organisms and the progression of </u><u>evolution </u><u>between them. </u>
