Umuc biology 102 / 103 lab 6: taxonomy answer key


This contains 100% redress esthetic for UMUC Biology 103 LAB06. However, this is an Retort Key, which instrument, you should put it in your own words. Short is a pattern for the Pre lab questions retorted:

Pre-Lab Questions

 

1. Use the forthcoming assortifications to determine which organism is smallest cognate out of the three. Explain your rationale. (1 pts)

 

 

The Eastern Newt is the smallest cognate organism out of the three. While all three are assortified into the corresponding estate, dominion, phylum and assort the Eastern Newt is in a divergent arrange than the American Green Tree Frog and the European Fire-Bellied Toad.

 

2. How has DNA sequencing monstrous the experience of assortifying organisms? (1 pts)

DNA sequencing has disclosed for the comparison of genes at the molecular equalize as incongruous to material traits at the organism equalize. Material traits can be misleading when assortifying how cognate two organisms are. DNA sequencing can so delineate cognateness through generations and over accurately assess how closely cognate two organisms are.

 

3. You are on recreation and see an organism that you do not allow. Discuss what practicable strides you can engage to assortify it. (1 pts)

The organism’s material features can be used to collate it to disclosed organisms. Some physiological features can well-balanced perchance be used to aid assortify it.

 

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

2.    How does your retort from Question 1 detail to the Linnaean assortification scheme?

Post-Lab Questions

1.    Did this sequence of questions redressly frame each organism? Why or why not?

 

 

2.    What affixed questions would you ask to advance categorize the items amid the dominions (Hint: imagine environing other organisms in the dominion and what makes them divergent than the examples used short)?

 

 

 

3.    What questions would you keep asked instead of the ones that you retorted environing when assortifying the organisms?
