Hey Bonny959!
Terminal Velocity is reached when the drag force and buoyancy equal the force of gravity on a falling object!
Hope this helps!
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>

Chemical formula is the answer
You are observing the metaphase phase of mitosis
Mitosis is a process of cell reproduction in which a cell divides to produce two daughter cells that are genetically identical to the parent. Metaphase is the third phase of mitosis. During this phase, the two centrosomes pulls the chromosomes towards the opposite poles of the cell which causes the sister chromatids to line up neatly across the middle (equator) of the cell.
