<span>ANSWER: Radiometric dating shows the rate of decay of radioactive material present in any objects. Scientists can use that data to find the absolute age of the fossil.
The radioactive carbon method is a method used to determine the age of the fossil based on the ratio of the number of atoms of stable carbon isotope 12C and the radioactive isotope 14C. <span>During their lifetime, plants or animals exchange carbon with their environment, so the carbon-containing it will have the same percentage of 14C as well as the atmosphere. When a plant or animal dies, it ceases to collect 14C, but 14C within its biological material at that moment will continue to decompose. So, the ratio of 14C and 12C in residues will gradually decrease. Since the rate at which the 14C decay is known, the percentage of radiocarbon can be used to determine the time period that has passed since the sample was given to stop exchanging carbon with the environment (older sample - less 14C).</span></span>
<span>Characteristics of Enzymes : *Enzymes Made out of proteins and RNA. *Shape related to the function, names usually end in ase, catalyst. functions of enzymes is speed up chemical reactions by lowering the activation energy . Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.</span>
The answer could be the fact that all species posses 23 universal proteins. These proteins vary slightly in some DNA sequences but are pretty much the same. These proteins are responsible for tasks such as DNA replication and translation from DNA to proteins. These activities are crucial to all forms of life. The presence of these universal proteins suggest that modern life evolved from a single common ancestor.
