To determine: The biogeographic realm that has been separated from the other biogeographic realms for the longest period.
Introduction: The study of the earlier and current geographic distribution of plants and animals is called biogeography. It includes origin of patterns, origin of population, how they got there and when. According to the principle of biogeography, each species are originated only once from its center of origin. From this center of origin, all species spread until a barrier prevents them. The range of species is defined as the portion of the Earth in which it is found.
To determine: The animals that characterize Australian realm.

- Choose a catecholamine neurotransmitter and describe/draw the components of the synapse important for its signaling including synthesis, packaging into vesicles, receptors, transporters/degradative enzymes. Describe 2 drugs that can act on this system.arrow_forwardThe following figure is from Caterina et al. The capsaicin receptor: a heat activated ion channel in the pain pathway. Nature, 1997. Black boxes indicate capsaicin, white circles indicate resinferatoxin. a) Which has a higher potency? b) Which is has a higher efficacy? c) What is the approximate Kd of capsaicin in uM? (you can round to the nearest power of 10)arrow_forwardWhat is the rate-limiting-step for serotonin synthesis?arrow_forward
- What enzyme is can break down some but not all monoamines?arrow_forward6. 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.arrow_forwardBuild 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…arrow_forward
