6. The mammalian phylogenies (labeled a and b) were produced by two different research groups. a. In which tree do phylogenetic relationships most closely align with biogeography and why? (consult the Teeling and Hedges paper) b. What are the most closely related species to Chiroptera in each tree? Might the use of convergent traits for building phylogenies explain this difference? If so, which tree is most likely to have relied on convergent traits and why? c. What are some possible reasons that the two research groups came up with different phylogenies (in general terms)? describe at least three possible reasons.

Build a model of a prokaryotic cell using any material of your choice. In your model be sure to include all the structures appropriate to your cell. You may model a bacterial cell or an archaea. You will model at least 4 structures in any model. Next, build a model of a virus using the same type of materials. You may choose any type of virus but be sure you can illustrate the key features of a virus (head shape for example). Once complete, take multiple photographs of your models from all angles. Include these images in a document that also contains the following completed table format. You may need to add rows to your table depending on the type of prokaryote you model. Structure Model Key Found in Different in Function Virus Virus Once your model is complete, write a brief description of your cell and your virus. Emphasize features that are absent in viruses that classify them as non-living. You can refer to specific structures in your table in this explanation. Some suggestions for…

(This is a 2-part work, Part 1 is done, only Part 2 is to be worked on at the bottom)Part 1 (Done): Describe the levels of structural hierarchy for the human body, starting with the organismal level and ending with the chemical level. In addition, you should make sure you link each level to the previous level, emphasizing the structural relationships. The human body is organized into a structural hierarchy that progresses from the macroscopic organismal level down to the microscopic chemical level. Each level builds upon the previous one, creating increasingly complex structures. Below is the hierarchy, from largest to smallest, with explanations linking each level to its predecessor: 1. Organismal Level The entire living human body.Relationship: All lower levels work together to sustain life at this highest level. 2. Organ System Level Groups of organs working together to perform major functions.Examples: circulatory, nervous, digestive systems.Relationship: The organismal…
