You have isolated C57BL/6 embryonic stem cells and have tried a new culture condition to keep them pluripotent. To test for the success of your culture protocol, you are injecting the cells into a C57BL/6 blastocyst. Once the pups are born, you notice that your experiment failed. Why? HINT: It's related to chimera creation. (Donor blastocyst of a black fur mom vs. white fur foster mom. Foster mom will donate the blastocyst, and we will inject the derived ESC (ESL) of the donor mom into the blastocyst. We then implant it back to the foster mom and for the 1st generation of a chimera.)

2. If the adsorption of organic contaminant follows the Langmuir isotherm model (slope =2.7 and y-intercept= 6.5), determine the affinity of adsorbate for adsorbent ($K_{ads}$), and the maximum capacity of adsorbent for adsorbate $q_m$. based on estimated $K_{ads}$ and $q_m$ calculate the amount of adsorbent (gram) required to reduce the level of the organic contaminant to 0.2mg in 4L of water. initial concentration of the organic contaminant is 1mg/L.

Unit 4-Activity #2 Cost Estimation Name Problem 5 Corise's Cola was to manufacture 500 cases of cola next week. The accountant provided the following analysis of total manufacturing costs. Variable Coefficient Standard Error t-Value Constant 115 82.73 1.39 Independent variable 230 105.50 2.18 r2 = 0.82 1. What is the cost estimation equation according to the report? 2. What is the goodness of fit? 3. What is the estimated cost of producing the 500 cases of cola? Problem 6 The Perize Corporation used regression analysis to predict the annual cost of indirect materials. The results were as follows: Indirect Materials Cost Explained by Units Produced Constant $15,685 Standard error of Y estimate 3,500 r2 0.7832 Number of observations 20 X coefficient(s) 10.25 Standard error of coefficient(s) 2.1876 1. What is the total fixed cost? 2. What is the variable cost per unit produced? 3. Write the linear cost function. 4. What is the coefficient of determination? 5. Based on the above, I would conclude that there IS / IS NOT (circle one) a significant relationship between the cost of indirect materials and units produced.
