C. the cell membrane.
the membrane let's things in and out of the cell.
When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction between the air and the swing and between the chains and the attachment points slows it down and eventually stops it.
Answer:
Geological processes are those process that occurs on the surface and subsurface regions of the earth crust. They facilitate in shaping the Earth, and helps in concentration of resources over a region. These processes occurred millions of years ago, the chances are their that they will occur in future as well. Some of the major features of the California landscape develop as a result of plate tectonics and other features develop due to the process of erosion under the influence of wind, water, ice and other features.

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>
