PurposeTo introduce you to principles of taxonomy as you look at morphological characteristics of sea shells and construct an evolutionary tree.DirectionsGo to the link http://media.hhmi.org/biointeractive/click/shells_online/index.html and work through the lab sorting sea shells based on morphological characteristics to study evolutionary relationships.Please take notes for your laboratory report. You will add an introduction later. Write a short note describing each step of identifying and selecting snails as you work through the lab. Please take a screen shot of the final drawing showing the evolutionary relationship of all snails listed.Please answer the following questions:Why was the scallop among the snails? (HINT: Watch "Dr. Olivera discusses major molluscan groups")What additional tests could be used to examine evolutionary relationships among molluscs (snail species)? (HINT: Watch "Dr. Olivera discusses how to classify shells")How was the name of different cone snail specied decided? (HINT: Watch the video "Dr. Olivera discusses species names")Where are cone snails found and what are their feeding habits? (HINT: Click on snail images on the final evolutionary tree for more information about species).Describe the evolutionary history of snails (Molluscs). In which eon, era and period did the first snails evolve? (HINT: Textbook, chapter 15.3)The laboratory report will have a title page (APA format), and an introduction. Summarize the life history of cone snails. List your steps to classify the snails under methods, post the final picture of snail specis under results and discuss limits of morphological classification in the discussion section of the lab report. Suggest additional tests which may clarify cone shell taxonomy. You should also have a reference section, with the textbook and web page listed in APA format.Please review the grading rubric for the assignment for additional details and grade criteria. Also use the "How to write a lab report" links in the Grading Rubrics  folder for futhur guidance.

attached are two files for chemistry assignments all the questions and instructions are in the files

Report will be on this case: https://www.youtube.com/watch?v=j4rpPv0EG7Q5 PARTS:Title page - with appropriate titles and subtitles in the appropriate sections of the report. 1. Introduction: In this section, identify/describe the case/ forensic problem tobe solved (the link above). Include a rationale for why the problem is of interest and relevance to this forensic sciencecourse. Include why you're interested in this case (maybe because an important process is explained through it, or you're interested in blood spatter? etc.)2. Science and Methods Used: This is where the research comes in. Explain the science and the methods used in solving the case i.e. the analysis of evidence and the scientific tools and concepts discussed. Then evaluate the methods discussed (i.e. Are/Were the results accurate and adequate? What are/were the limitations?)example of Scientific evidence/tools used in this case:- Fiber-glass- Blood stain analysis/nature of the spatter- 911 voice-recording- DNA (No DNA of an unknown assailant)3. Societal Impacts and Legal Ramifications. - i.e.: - remaining child doesn't have siblings - why the murder was done (she was depressed, they were behind on their mortgage, etc.) - address the death penalty4. Conclusion: students are expected to synthesize the material and summarize the casecovering the Science and Societal Impact.5. Bibliography: 1 page. Number the references. MUST include 2 scholarly references, 1 textbook reference (Tom Bevel's book is recommended to use for the Blood portion- http://index-of.co.uk/Tutorials-2/Bloodstain%20Pattern%20Analysis%20-%20An%20Introduction%20to%20Crime%20Scene%20Reconstruction.pdf), and the video itself is one reference that must be cited - CITE WITH PAGE NUMBERS, AND USE FOOT NOTES- Use the same format for all the references cited for consistency.
