Answer:
Due to cell wall.
Explanation:
Scientists were able to easily identify the cells in plants first as compared to animal cell because the plant cell has cell wall while the animal cell has no cell wall only cell membrane. The structure of plant cell is just like the compartments and the cell wall provides the boundary between two cell which enable the scientist to see the plant cell first.

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>
