Metazoa Guides d'étude, Notes de cours & Résumés

This document contains notes on all lectures. I added some information where necessary to make it more elaborate. This document also contains a table regarding the virulence of Toxoplasma gondii, which was an assignment to read and present.

BIS 2C Postlab 7: Introduction to Metazoa (Graded A+)

BIS 2C Pre-Lab 7: Introduction to Metazoa (Graded A+)

Pre-lab: Introduction to Lab 8 In this, the *nal lab of the quarter, you will be asked to solve a series of small puzzles in metazoan evolution. In BIS 2A you learned about mechanisms of genetic change, and in BIS 2B you learned how natural selection operates on individuals to produce genetic change in populations. You realize now that agents of natural selection can be biotic factors, such as interactions with predators and prey, as well as abiotic factors, such as temperature or moisture...

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...

NSG 221 FINALScreening program - correct answer -conducted by community health nurses -guidelines: -screen for conditions in which early detection and treatment can improve disease outcome and quality of life - screen populations that have risk factors or are more susceptible to the disease - select a screening method that is simple, safe, inexpensive to administer, acceptable to clients, and has acceptable sensitivity and specificity - plan for the timely referral and follow-up of...

Phylogeny (USABO) FINAL EXAM 2024. Chytridiomycota (chytrids) - ANSWER flagellated spores; fungi Zygomycota (zygomycetes) - ANSWER resistant zygosporangium as sexual stage; fungi Glomeromycota (arbuscular mycorrhizal fungi) - ANSWER arbuscular mycorrhizae formed with plants Ascomycota (ascomycetes) - ANSWER sexual spores (ascospores) borne internally in sacs called asci; vast numbers of asexual spores (conidia) produced; fungi Basidiomycota (basidiomycetes) - ANSWER elaborate fr...

Be familiar with the common characteristics of animals. - - Multicellular heterotrophs - cells lack cell walls -most have nerves, muscles, and capacity to move at some point in the life cycle - able to reproduce sexually - specialized sensory structures and nervous system - cells exist in extensive extracellular matrix - unique cell junctions What type of life cycle do all animals show? - gametic What is the most likely ancestor of animals? - choanoflagellates What are the 3 major featu...
