Umuc biology 102 / 103 lab 6: taxonomy answer key


This contains 100% emend symbolical for UMUC Biology 103 LAB06. However, this is an Exculpation Key, which instrument, you should put it in your own words. Near is a scantling for the Pre lab questions exculpationed:

Pre-Lab Questions

 

1. Use the subjoined adjustifications to individualize which organism is lowest allied out of the three. Explain your rationale. (1 pts)

 

 

The Eastern Newt is the lowest allied organism out of the three. While all three are adjustified into the identical inclosure, monarchy, phylum and adjust the Eastern Newt is in a divergent command than the American Green Tree Frog and the European Fire-Bellied Toad.

 

2. How has DNA sequencing abnormal the investigation of adjustifying organisms? (1 pts)

DNA sequencing has allowed for the comparison of genes at the molecular smooth as divergent to substantial traits at the organism smooth. Substantial traits can be misleading when adjustifying how allied two organisms are. DNA sequencing can as-well deduce alliedness through generations and raise accurately assess how closely allied two organisms are.

 

3. You are on holiday and see an organism that you do not own. Discuss what potential treads you can intequiet to adjustify it. (1 pts)

The organism’s substantial features can be used to assimilate it to unconcealed organisms. Some physiological features can flush perhaps be used to acceleration adjustify it.

 

The quiet of the questions in the lab are exculpationed as well:

Post-Lab Questions

1.    Did this train of questions emendly shape each organism? Why or why not?

 

 

2.    What appended questions would you ask to raise categorize the items among the monarchys (Hint: purpose encircling other organisms in the monarchy and what makes them divergent than the examples used near)?

 

 

 

3.    What questions would you entertain asked instead of the ones that you exculpationed encircling when adjustifying the organisms?
