I believe the answer is Planet Nine.
Answer:
I believe the correct answer is both involve proteins in the cell membrane.
Explanation:
This is because Facilitated diffusion does not require any energy to transport molecules, while Active transport requires ATP. Facilitated diffusion transports molecules from an area of higher concentration to an area of lower concentration (or down a concentration gradient). Active transport moves molecules from an area of lower concentration to an area of higher concentration (or up a concentration gradient). Answer choice A is the only choice that makes sense.

Answer:
<em>The evidence that suggests RNA appeared before DNA is the fact that RNA can act as an enzyme to self-edit their own genetic code. </em>Moreover, it has the ability to store genetic information, while transfer and ribosomal RNA have the ability to translate genetic information into proteins.
Explanation:
RNA has a great capability as a genetic molecule, it once had to carry on hereditary process on its own. It is absolutely sure that RNA was the first molecule of heredity. However, a single stranded RNA is rather unstable and easily damaged by enzymes. By essentially multiplying the existing RNA molecule, and using deoxyribose sugar instead of ribose.
<em>The DNA evolved as a much more stable form to pass genetic information with accuracy. It shows a biological evolutionary purpose .</em>
