Umuc biology 102 / 103 lab 6: taxonomy answer key


This contains 100% chasten symbolical for UMUC Biology 103 LAB06. However, this is an Defense Key, which media, you should put it in your own language. Close is a illustration for the Pre lab questions defenseed:

Pre-Lab Questions

 

1. Use the aftercited tabulateifications to determine which organism is last cognate out of the three. Explain your rationale. (1 pts)

 

 

The Eastern Newt is the last cognate organism out of the three. While all three are tabulateified into the identical lordship, sovereignty, phylum and tabulate the Eastern Newt is in a divergent regulate than the American Green Tree Frog and the European Fire-Bellied Toad.

 

2. How has DNA sequencing monstrous the information of tabulateifying organisms? (1 pts)

DNA sequencing has undisputed for the comparison of genes at the molecular equalize as divergent to substantial traits at the organism equalize. Substantial traits can be misleading when tabulateifying how cognate two organisms are. DNA sequencing can also follow cognateness through generations and aid precisely assess how air-tight cognate two organisms are.

 

3. You are on holiday and see an organism that you do not acknowledge. Discuss what potential trudges you can charm to tabulateify it. (1 pts)

The organism’s substantial features can be used to collate it to disclosed organisms. Some physiological features can flush perchance be used to succor tabulateify it.

 

The tranquillity of the questions in the lab are defenseed as well:

Post-Lab Questions

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

 

 

2.    What subjoined questions would you ask to aid categorize the items amid the sovereigntys (Hint: consider encircling other organisms in the sovereignty and what makes them divergent than the examples used close)?

 

 

 

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