Answer:
Using the concept of relative dating
Explanation:
Scientists use the concept of relative dating principles to determine when the Great Oxidation event occurred.
Relative dating is the process of placing ancient event in their proper time sequence based on the relationship between rock lithologies.
- An event like the great oxidation will have significant chemical, biological and physical effect on the rock units.
- Rocks that form during this period in time will have very unique chemical signatures.
- Therefore, by studying these rocks, the age of the layer can be fixed when we compare it to the standard geological column.
DNA is a macromolecule composed of nucleotides which carry the genetic instructions used in the growth, development, functioning and reproduction of the cell. One of the most important characteristics of DNA is its ability to make several copies of it (to be copied via the process of replication). When the cell divides into two it must carry each copy of DNA into the divided cells. Through replication, the DNA transfers the information necessary for creating an exact copy of it in the new daughter cell. The transfer of the DNA to the next generation of cells is essential for the function of the whole organism.
<span>DNA replication will make the organism to reproduce the genetic code and transfer it to the next generation (through the reproduction) and thus, to continue the species. </span>

42. In Anaphase 1, homologous chromosomes separate to each side of the cell, and the centromere is intact while in Anaphase 2, the sister chromatids separate and the centromere splits into two which result in two separate chromatids.
Hope this helps and you get your grade up lol

Cell membranes are first proposed to be composed of phospholipid bilayers by Singer and G. Nicolson.
<h3>What do you mean by cell membrane ?</h3>
A cell membrane, often referred to as a plasma membrane, is present in every cell and serves as a barrier between the interior of the cell and the outside world. The cell membrane is a lipid bilayer that is semipermeable. The passage of chemicals into and out of the cell is regulated by the cell membrane.
- As a result, the cell membrane has two functions: first, it acts as a barrier to keep the cell's components in and undesirable substances out, and second, it acts as a gate to allow the entry of essential nutrients and the exit of waste products.
