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...

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 4: Introduction to Plant Diversity I

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...

BIS 2C “Biodiversity and The Tree of Life” Midterm 2 Study Guide: Plantae Lineage The Non-vascular plants-Bryophytes/Embryophytes: 1. Early non-vascular plants including Charates and Coleochaete (outgroup-streptophytes) had phragmoplast, branched filaments, apical growth (meristems), and oogamy. 2. Bryophyte: A small flowerless green plant of the division Bryophyta, which compromises the Mosses (Polytrichum), Hornwort (Anthoceros), and Liverworts. • Traditional name used to refer ...

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
