<span>If I were attempting to date a rock sample that I suspect to be incredibly old, i would use radioactive isotopes with a long half life. When dating rocks and fossils to discover approximately how old they are, radioisotope dating is used on igneous rocks found near fossils. Things like Uranium 235, which is an unstable radioactive isotope of elements, decays at a constant rate over time so can be useful in determining age.</span>

Answer;</u></h3>
C. Different species can share the same common name.
<h3><u>Explanation;</u></h3>
- <em><u>Different organisms can share the same common name</u></em>, and thus the reason why scientists avoid using common naming while naming organisms.
- Additionally, s<em><u>cientists avoid using common names because they are not specific to a specific species.</u></em> For instance, Robin is a common word that may be used to describe the many species of robin that are found in different regions of the earth, for example, Robin in England which has yellow breast, and robin in United states and have red breasts.
- Therefore, <em><u>for the purpose of avoiding ambiguity and confusion in naming organisms scientists use scientific names while identifying various species.</u></em>
Answer: <u><em> Microevolution is defined as a change in allele frequencies in a population over time. Three mechanisms can cause allele frequencies to change: natural selection, genetic drift (chance events that alter allele frequencies), and gene flow (the transfer of alleles between populations).</em></u>

Explanation:
Atherosclerosis refers to the condition in which the plaque gets accumulate within the blood vessels' walls. In the condition, inflammation occurs in the arteries' inner lining. The following is the sequence of events that results in atherosclerosis is:
1. A huge concentration of LDL cholesterol gets gathered within the inner walls of the arteries.
2. This causes discharging of macrophages to the site.
3. The engorgement of WBCs takes place with fatty deposits.
4. The hardening of plaques takes place, which eventually prevents the flow of blood in the prime arteries.
