A) David, an undergraduate research assistant in our lab, performed Western Blotting experiment and he used anti- Z protein polyclonal antibody raised in rabbit as a primary antibody. As a secondary antibody, he used anti-mouse HRP labeled antibody. Could you please tell him what is wrong with this experiment? B) David, an undergraduate intern in our lab, forget to block the blot with BSA and continue to the antibody hybridization steps and finally developed his blot. Could you please describe...

I recently performed a lab on Chemical Equilibrium. Here is some background on the experiment: -We made a stock solution by combining Fe(NO3)3 and NH4SCN. This made a blood red solution. Then, we added different reagents to see the change of color and the shift of equilibrium. I'm being asked the following question: Based on the color of solutions reported, determine the direction of the reaction's: Fe^3+(aq)+SCN^- --> [FeSCN]^2+(aq) equilibrium shift upon each addition of each reagent investigated and write...

Design an experiment that you could perform in our lab to determine the coefficient of kinetic friction and static friction and to compare the coefficient of kinetic friction and static friction. A good design should include details of the materials and equipment needs, the experimental procedure, including precautions, the types of data you will collect, how the data will be represented and analyzed, and how you will determine the accuracy of your experimental result(s).

2. An experiment was conducted to determine if a drug could be used as a treatment for the eating disorder anorexia. The test subjects were women being treated for anorexia. A group of 50 patients received the drug, and after a year, 39 were deemed healthy. Construct a 99% conﬁdence interval for the true proportion of patients who would be deemed healthy after receiving the drug for a year.

This Code Is Supposed To Be Performed In JAVA 1.) Create an abstract class DiscountPolicy. It should have a single abstract method computeDiscount that will return the discount for the purchase of a given number of a single item. The method has two parameters, count and itemCost. Create a driver class that tests this class and provide the UML. 2.) In a separate program, define DiscountPolicy as an interface instead of the abstract class. Create a driver class that tests...

. An experiment was performed on a certain metal to determine if the strength is a function of heating time (hours). Results based on 20 metal sheets are given below. Use the simple linear regression model. ∑X = 40 ∑X2 = 200 ∑Y = 80 ∑Y2 = 1120 ∑XY = 460 Find the estimated y intercept and slope and write the equation of the least squares regression line. Estimate Y when X is equal to 3 hours. Also determine the...
