Chromosphere - This layer of the Sun is located between 250 miles and 1300 miles above the photosphere. The chromosphere has temperatures around 4000K at the base, and 8000K at the top.

Transition Region - This layer is very thin with a size of about 60 miles, and it is present between corona and the chromosphere.

Corona - This layer is the Sun’s outermost layer. It starts at roughly 1300 miles over the photosphere and it has no upper limit. Its temperature is between 500,000 K to 1 million K.

Which of the following makes the most sense when it comes to the evolution of primates?

Pavlova-9 [17]

The correct answer is Humans and chimpanzees have DNA that is very similar because they both evolved from a common ancestor.

Explanation:

Both humans and chimpanzees are primates; this means both species belong to the same biological order (rank in taxonomy). Moreover, humans and chimpanzees share most of their DNA (around 99%). This indicates the two species are related and they evolved from the same ancestor. This implies a primate that existed million years ago (common ancestor) was the origin of these two species and due to this common ancestor they share most of their DNA; however, as both species changed separately the remaining DNA is different and this makes both species look and be different. According to this, the correct statement about the evolution of primates is "Humans and chimpanzees have DNA that is very similar because they both evolved from a common ancestor."
