The Eastern Newt discussion

This contains 100% correct material for UMUC Biology 103 LAB06. However, this is an Answer Key, which means, you should put it in your own words. Here is a sample for the Pre lab questions answered:
 
 
Pre-Lab Questions
 
1. Use the following classifications to determine which organism is least related out of the three. Explain your rationale. (1 pts)
 
 
The Eastern Newt is the least related organism out of the three. While all three are classified into the same domain, kingdom, phylum and class the Eastern Newt is in a different order than the American Green Tree Frog and the European Fire-Bellied Toad.
 
2. How has DNA sequencing affected the science of classifying organisms? (1 pts)
DNA sequencing has allowed for the comparison of genes at the molecular level as opposed to physical traits at the organism level. Physical traits can be misleading when classifying how related two organisms are. DNA sequencing can also trace relatedness through generations and more accurately assess how closely related two organisms are.
 
3. You are on vacation and see an organism that you do not recognize. Discuss what possible steps you can take to classify it. (1 pts)
The organisms physical features can be used to compare it to known organisms. Some physiological features can even possibly be used to help classify it.
