Step 1: select two different species (one eukaryotic and another prokaryotic and do the taxonomy. Step 2: Classify each one based on modern taxonomy, and write their scientific name in three different ways based on Linnaeus. Step 3:Describe their dichotomous key and show how far they are in their taxonomy from each other and describe how they interact together in the ecosystem based on what you studied. Step 4: - Take screenshots of their location in the phylogenetic tree

Species A was recently discovered and its DNA sequence was compared to the DNA of the four previously known species from the same genus. The comparison revealed this particular species is the most recent one, the one that diverged last. Show the mismatched nucleotides between these DNA sequences (mark them and count them) and then draw a phylogenetic tree that shows their relationship. You can draw the tree by hand.Species A 5’ A A G G C C A A A C T T T G G G T A T A G C A T A 3’Species B 5’ A A G G C C A A A C C G T G G G T A T A G C G A A 3’ ____________Species C 5’ A A G G C C A A A C T T T G G G T A T A G C G A A 3’ ____________Species D 5’ A A C T C C A A A C C G T G G G T A T A G C G A A 3’ ____________Species E5’ A A G G C C A A A C T T T G G G T A T A G C G T A 3’ __________

KO> O The diagram below represents four different species of bacteria. Species A Species B Species C Species D TTT Which statement is correct concerning the chances of survival for these species if there is a change in the environment? O Species C has the best chance of survival because it has no gene mutations. O Neither species B nor species D will survive because they compete for the same resources. O None of the species will survive because bacteria reproduce asexually. O Species A has the best chance of survival because it has the most genetic diversity. 1 4 7 8 10 Next O 1 N CH I O

Using the information from the DNA-DNA hybridization data table below, build a phylogenetic tree that shows the relationship between species E,R,P,G, and U. Create a scale on the side before you draw it

Compare taxonomic and phylogenetic classification. How are each of these systems used to organize the natural world? In the case of microorganisms, which system is considered most accurate? Why?.

Make a list of species that are suitable for collection and preservation. How do you prolong the life of specimens collected?
