Answer:
To study the evolutionary relationships of the earliest forms of life on Earth we need to examine a structure that is present in all cells and changes very slowly over time.
All life on Earth was initially divided into three main Domains: the Bacteria, the Archaea, and the Eukarya, based on the similarities of their:
Ribosomal RNA
Explanation:
Ribosomal ribonucleic acid: RNA (rRNA, mRNA, and transfer RNA (tRNA), is a noncoding molecule of RNA in cells, which is the main building block for ribosomes protein-synthesizing organelle, exported to the cytoplasm to help translate the information in messenger RNA (mRNA) into protein. They are essential to all living organisms.
Because all these cells are similar in nature within the bacteria, the archaea and the eukaryait, there is a thought that all cells came from a common universal ancestor cell that eventually evolved into three different kind of cells, representing each of these domains.
Answer:
Second location from right to left
Explanation:
This is the location that has the greatest chance of escaping the bubonic plague. The reason is that this location is not near any major trade route. Trade routes were dangerous during this time period because they were areas where many different people from different places interacted. This meant that the risk of spreading the disease was larger. Therefore, towns that were located along major trade routes were the first ones to be badly affected by the disease.
