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
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.
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.
The organism’s physical features can be used to compare it to known organisms. Some physiological features can even possibly be used to help classify it.
The rest of the questions in the lab are answered as well:
