Answer:
Explanation: When this study was carried out by Meselson and Stahl, their findings are compatible with the trend expected by semi-conservative analysis, establishing this as the right template. The two parent strands are split as DNA replicates, and each strand acts as a blueprint for a new DNA strand synthesis.
After the first replication, there are two DNA double helices each marked as superscript 14 N slash superscript 15 N. After the second replication, four double helices of DNA are produced. Three of them are marked as 14 N superscript slash 15 N. Two other DNA was marked as 14 N slash superscript 14 N.
Remember that after a round of testing, Meselson and Stahl were able to rule out the moderate template based on the results. At that point, though, they were unable to rule out the dispersive model because that model predicts the same trend as the semiconservative model. But after two trials, the findings made it possible for them to rule out the dispersive design.
The correct answer is option (A) to discover new aspects of the natural world.
The study of rock formations and living organisms in previously unexplored water habitats helps a scientist to discover the newer aspects of the natural world. The unexplored water habitats are the best source to understand the newer aspects of the aquatic bodies like the new species of plants or animals, factors affecting the aquatic life and the different types interactions in the habitats. The study of rock also helps in the study of plants and animals, which were once a part of the habitat, now in the form of fossils.
Thus, the study of rock formations cannot explain the recently observed phenomena as they help in the study of fossils. The study of living organisms in previously unexplored water habitats cannot be applied to test the conclusions of prior investigations and test the predictions of current theories as they remained unexplored.
They form organs so the human body can support itself and live. Hope this helps.
The right answer is A. An impact of changing scientific knowledge on society
