Scientists establish the age of a rock or fossil based on natural radioactive decay and certain elements such as potassium and carbon, this is used to make reliable “clocks” to date ancient events.

Answer:
<em>Hox </em>Gene
Explanation:
First, you're question is very vital, there are many ways in classifying along with identifying all living organisms that includes; morphological analysis, molecular systematics (studying the similarities and differences of the genetic data such in the sequences of DNA, RNA, and rRNA ), homology, cladistics, etc. based on phylogenetic tree, which the study of the evolutionary among various species.
But through it said that all living organisms shared one common ancestor. However, what makes them different from one to another is the homeotic genes that called <em>Hox </em>Genes; which specify the fate of a particular segment or region of the body, meaning the number and arrangements of the<em> Hox</em> genes varies considerably among different types of animals.
For instance, Sponges have at least one homologous to<em> Hox</em> genes, also insects have nine or more <em>Hox </em>genes resulting in multiple <em>Hox </em>genes occur in a cluster in which the genes are close to each other along a chromosome. Therefore, increases in the number of<em> Hox</em> genes have been instrumental in the evolution of many animals species with greater complexity in body structure.
Overall, more <em>Hox</em> genes, more complexity in body structure resulting in the differences of their morphological structure.
Hope that answered your question!
Complete Question:
What would most likely be included in the “Analysis” section of a lab report?
1) a discussion of any errors in the experimental data
2) a list the supplies that were used in conducting the experiment
3) suggestions for new experiments based on the results
4) a description of what the dependent and independent variables were
Answer:
1). <u>a discussion of any errors in the experimental data</u>.
In the analysis section of the lab report, after analyzing and investigating the data, errors are identified in the experimental data. Furthermore, discussion carried out to point out those error occurred in the data. In an analysis process discussion is carried out to find the errors in the whole process. In this process all facts and figure are gather to inquire if there are any errors or mistake present in the final values or final result. Analysis section in a lab report has a key role because it make sure that the final result is error free.
Your answer is a , atoms .
