This I need finish fast The purpose of the following activity is to assess name brand versus generic brand products (similar to what you did in the on campus lab session when you looked at various antacids). Perform the following activity, and report your findings in your initial post. 1.) Consider a name-brand product and its similar generic product. (For example, opti free contact lens solution vs. target brand contact lens solution.) 2.) Compare the ingredients (especially the active ingredients) in the name-brand product with those in the generic product. 3.) If the active ingredients are different, determine which, if either, does a better job of accomplishing the product's objective. (You may have to do an internet search here. If so, provide the name and link of any website from which you find information. In all cases, be sure to present information in your own words.) 4.) Compare the cost of the name brand product with the cost of the generic product. 5.) Based on your findings, is it better to purchase the name-brand product, or will the generic product suffice? Be sure that your initial post includes all of the above information. Once you post your initial response, return to the discussion forum throughout the module and answer any replies to your initial post, and respond to at least two of your classmates' initial posts. Try to respond to those classmates that do not yet have responses from other students. When responding to your classmates' posts, you must do one of the following: Provide additional input: Do not simply reply to a post by saying "I agree with you" or "I disagree". Instead, explain why you agree or disagree, and build upon the initial post. Offer suggestions: If you feel your classmate is on the right track (or completely off base) and can improve in his/her response, offer ideas on how improvements can be made. Ask a question: If there is something unclear about a post, ask a question to promote further discussion. Please refer to the course calendar for appropriate due dates and the rubric below for grading information.
