The correct answer is the second choice - peer review process in scientific research exists in order to verify that the conclusions that are made are supported by the data. You cannot make a valid conclusion if you do not have enough evidence or data to prove it - this is why your peers have to go through your research to make sure everything is done according to the rules of scientific research.
Hope this helps.
Answer:
by looking at their physical features, the fossil record, and dna sequences
This question is incomplete. However, the answer to this question is Continental Drift. Approximately 300 million years ago, there were not separate continents, only one giant super continent that we call Pangaea. Over time, scientists realised that the Earth's outer shell slides over the inner mantle through plate tectonics. Around 200 million years ago, Pangaea began to break up through the process of continental drift. Gondwana, incorporating present-day <span>Africa, South America, Antarctica, India and Australia, split from Laurasia (Eurasia and North America). Approximately 150 million years ago, Gondwana started to break up into the present day continents</span>
The double membrane. It's theorized that chloroplasts used to be their own single-celled organism in the environment (and therefore with its own membrane). Then, the theory states, a larger cell took in the chloroplast by endocytosis, which involves surrounding the chloroplast in the large cell's own membrane. The chloroplast would then have two membranes surrounding it. This is similar to the thinking for mitochondria becoming an organelle as well. Hope this helps! :)
