Can they be proven with science

The goal of your Signature Assignment is to show that you can compute properties of solutions and analyze and interpret data. You will create a PowerPoint presentation that shows the process of going through an acid/base titration like you would if you were in a physical lab.For the presentation:You will prepare a sample of an unknown acid to titrate using a known concentration of base. You will set-up a burette filled with a known concentration of base and use proper titration techniques to reach an end-point to the titration. You will then calculate the concentration of the unknown acid on your own.For Part I:Create a PowerPoint presentation (4-6 slides) that covers the lab scenario above.Include your thoughts on why understanding acid/base titration is important to your future career, and how you will use this concept as you complete your degree.Your presentation must consist of more than merely a series of bullet points to earn full credit.Use the Notes section for each slide to fully explain your answerDear Students,Your lab assignment presentation involves putting together a presentation to show other students on how to perform titration. In other words, your presentation can be used to show other students (next term) how they can perform a titration by following your instructions and calculations. 2) To do this presentation, we are giving you the type of acid, acetic acid, the type of base, NaOH to be used, and you will use phenolphthalein as the indicator. You will use the data given to you to be used as an example of how to solve the mathematical calculations. At the end of your presentation, you will show the unknown concentration of the acetic acid (Molarity) and will also show the % mass/ vol of the Vinegar solution. Part 11. Purpose of a titration, what is titration and why do we perform a titration?2. Instrumentation- what are the instruments, glassware used when performing a titration.3. Chemicals and Procedures. What chemicals are needed? List and explain the procedures for this experiment.4. Observations and expectations- List the observations and write your expectations. This might include color change and when the equivalence point (endpoint) might be reached.Part 21. Calculations and Results. Show all your calculations and write your results, the Molarity of the acetic and the % of the acetic acid.2. Your instructor will provide guidance and examples for completing calculations for titration.This assignment should be in current APA Style with both a title slide and a reference list that includes all the sources used. At least two scholarly sources should be used (your textbook can be one of the sources).

Attached.The Trouble with Vision Pedigree A woman by the name of Stella Hansen had an eye condition that none of the other women in her family had. She married a man called Alfred Jones who did not have the eye condition. They had six children, Samantha, Carrie, Teresa, Randall, Herbert and David. All three boys had the eye condition but none of the girls displayed this eye condition. Samantha married John who did not have the eye condition and they had three sons Ben, Jerome and William. Ben and William both had the eye condition but Jerome did not. Draw a pedigree using squares and circles and darken in all the affected individuals. Use Roman numerals for the generations and use the names to show individuals in the pedigree. Make a representation of this family using a pedigree drawn freehand on paper or use the computer. Make sure you provide a key to represent male, female and affected male or female with your pedigree drawing. After you finish your drawing ask your instructor to check it. Answer the questions below. Is this condition recessive or dominant? Explain why you think your answer is correct. What is the genotype of Stella Hansen for the eye condition? Could this condition be a sex-linked trait? Explain why you think it is or isn’t. What genotype do you think Samantha might be for this eye condition? From the information given are there any other people in this pedigree that you can guess their genotype? Write the genotypes of all the people you believe there is sufficient information. Is there any member in this pedigree that you believe you do not have enough information on to guess their genotype? Who are they? Do you know what kind of trait this vision condition is? What is it? Webbed Toed Wonders A family has an unusual trait having webbing to the tips of their toes in affected family members. The grandmother had this condition but the grandfather did not. There were six children in the second-generation--three boys Philip, Paul and Samuel and three girls Jessica, Jenny and Joan. Three of the children had webbed toes--Paul, Samuel and Joan. Philip, Jessica and Jenny did not have webbed toes. Paul married and also had six children Joseph, Jacob, Joshua, Jane, Sandy and Nicole. Paul’s wife does not have webbed toes, neither do any of his three sons. However, all three of Paul’s daughters have webbed toes. Draw a pedigree using squares and circles and darken in all the affected individuals. Use Roman numerals for the generations and use the names to show individuals in the pedigree. Get an additional sheet of paper or use the backside of the vision pedigree. Then, draw a representation of the family using a pedigree. Make sure you provide a key to represent male, female and affected male or female with your drawing.After you complete your pedigree and your instructor checks it, answer the questions below. Can you determine whether this condition for webbed toes is dominant or recessive? Explain your answer. Can you determine whether this trait is sex-linked by the information given? Explain why or why not. If webbed toes are sex-linked does it make sense that all of Paul’s daughters would have webbed toes and none of his sons? Explain your answer. Can you determine the genotype of the grandmother because two sons and a daughter had the condition and two daughters and one son does not? Explain your answer. If Paul had the gene for webbed toes of his X-sex chromosome would any of his sons be able to inherit this condition from him? Explain your answer and provide a Punnett square. Can the condition for webbed toes be recessive if it is a sex-linked trait on the X-sex-chromosome? Explain your answer. Is it possible that the condition for webbed toes is on another set of chromosomes other than the sex chromosomes? Explain your answer.
