Pre-lab 4: Introduction to Plant Diversity I #1 Based on the figure is it correct to state that we understand deep relationships about Eukaryotes? How do we represent ambiguity in branching pattern on phylogenetic trees No because there is no first node, just several species that branch out as possible base taxa. The ambiguity is represented through the polytomy. #2 Do a little internet research and provide t

Pre-lab 6: Botanical Conservatory and Fungal Diversity (Score: 4.75/5) Question 1. Identify two reasons why maintaining a large, living plant collection is an important public and scientific resource. It lets us study different types of plants without having to travel all over the world and it teaches us better methods of conservation. Question 2. In figure 6.2 above, which season (X or Y) would correspond to winter at point A? Season X Question 3. On which side (left or right) of figure...

Question 1. What two things do nodes represent on phylogenies? Nodes represent the most recent common ancestor of two or more descendant lineages and represent a speciation event. Question 2. Compare the branching patterns of phylogenies 1-3 above. Which statement below correctly describes the patterns among trees 1-3? Tree 1 = Tree 2 Question 3. Which node represents the MRCA for taxa F and G? 3 Question 4. Which taxon or taxa is/are the sister group to E + F? D, G, H Questi

1. Based on what you learned in lab 1, and assuming the relationships shown in figure 2.1 are correct, do ‘prokaryotes’ form a monophyletic group? No 2. Based on figure 2.2, are the groups labeled “Archaea” monophyletic in the “two-domain” hypothesis? Yes 3. Bacillus anthracis - d Vibrio cholerae - f Chlamydia trachomatis - e Lokiarchaeota - c Yersinia pestis - b Thermus aquaticus - g Staphylococcus aureus - a 4. Based on table 2.2, to which class of ‘trophy’ do hum...

Pre-Lab 7: Introduction to Metazoa (Score: Question 1. Study the phylogeny of animals in figure 7.3. Where are humans on this phylogeny? What are the defining features of the phylum to which humans belong? Humans are on the chordata. The defining features are notochord, dorsal hollow nerve chord, and post-anal tail. Question 2. Study the phylogeny of animals in figure 7.3. What feature of the phylogeny supports the fact that deep relationships among animals remain unresolved? Polytomy:sho...
