answer:Thank you for providing the relevant information from the output. Based on the provided output, we can determine the answers for Question 71. The researcher reported that the predicted blood glucose of an individual with a BMI of 30 would be "4.756788 + (0.032477 * 30)". The amount of variation in blood glucose explained by BMI is not directly given in the output. To determine this, you can check the "R-squared" value or "Multiple R-squared" value present in the output. Alternatively, you can calculate it using the ratio of the sum of squares for the model (346.1) and the total sum of squares (5976.7). Please note that without the exact values for the predicted blood glucose and the variation explained by BMI, I cannot provide the specific answers. However, you can use the given information from the output to calculate the answers for Question 71.

answer:Yes, based on the provided information from the output, we can calculate the percentage of variation in blood glucose explained by BMI. To do this, we can use the R-squared value. The R-squared value represents the proportion of the total variation in the response variable (blood glucose) that can be explained by the predictor variable (BMI). In the output, the R-squared value is not explicitly provided. However, you can calculate it using the ratio of the sum of squares for the model (346.1) divided by the total sum of squares (5976.7). The formula for calculating R-squared is: R-squared = (Sum of Squares for the Model) / (Total Sum of Squares) In this case, the R-squared value would be: R-squared = 346.1 / 5976.7 To find the percentage, you can multiply the calculated R-squared value by 100. Percentage of variation in blood glucose explained by BMI = R-squared * 100 Please calculate the R-squared value using the provided information and substitute it into the above formula to find the percentage of variation in blood glucose explained by BMI.

question:Now that you have weighed out the required amount of NaCl required for 150 mM final concentration, calculate the values for Y and Z. Procedure continued Step 2: Determine the volume of 0.5M Tris-HCl buffer required for 50mM final concentration 2.1 Measure out Y ml of 0.5M Tris-HCl buffer Step 3: Dissolve NaCl in Z ml dH2O Step 4: Add required volume of 0.5M Tris-HCl buffer to the 150 mM NaCl solution Question 64Answer A. Y = 100, Z = 3800 B. Y = 200, Z = 3800 C. Y = 50, Z = 3600 D. Y = 400, Z = 3400 E. Y = 100, Z = 3900

answer:To calculate the values for Y and Z, we need additional information about the quantities of NaCl and the final volume of the solution. Please provide the relevant information to proceed with calculating the values for Y and Z.

question:Tris-buffered saline (TBS) is a solution that is very commonly used for washing and suspending living cells in order to carry out experiments under defined conditions. TBS contains 150 mM NaCl and 50 mM Tris-HCl buffer pH 7.6. You are asked to make up 4 litres of TBS for your project. You are provided with solid NaCl and a stock solution of 0.5 M Tris-HCl buffer pH 8.0. How do you proceed? Procedure For Step 1, calculate the amount of NaCl that should be weighed out. Select the correct weight from the drop-down list. Step 1: Calculate amount (in grams) of solid NaCl required for 150 mM final concentration Mw NaCl = 58.44 Select the drop-down menu/box to select the CORRECT answer. (4 marks for this question) Weigh 35 g NaCl

answer:To proceed with making 4 liters of TBS, we need to calculate the amount of solid NaCl required for a final concentration of 150 mM. The molar mass of NaCl is 58.44 g/mol. To calculate the amount of NaCl in grams, we can use the formula: Mass (g) = (Molarity (M) * Volume (L) * Molar Mass (g/mol)) / 1000 Substituting the given values: Mass (g) = (0.150 M * 4 L * 58.44 g/mol) / 1000 Simplifying: Mass (g) = (0.87696 g) Therefore, we need to weigh out 35 grams of NaCl to make up 4 liters of TBS with a final concentration of 150 mM. Correct answer: Weigh 35 g NaCl
