Why was DCPIP added to the reaction in the cellular respiration lab?

By now, you have used various containers and have measured different volumes of liquid using different tools.  It’s important not only to follow protocols but also to develop a sense of what different volumes look like and which containers are appropriate for each amount. You are following a lab protocol that requires you to measure 0.5 mL of liquid. Based on what you’ve seen and used in lab, which of the following images best represents 0.5 mL of liquid?   

From the molecules listed below, penetrates the plasma membrane the fastest, while crosses it the slowest.

Consider the titration of 50.0 mL of 0.070 M weak base with 0.045 M strong acid (assume a 1:1 mole ratio of acid:base). Calculate the pH after 75.0 mL of strong acid has been added. The Kb of the weak base is 4.75 x 10-6.

Select the best answer for  the x_bar coordinate for the centroid of the cross-section shown above. (Reported to four significant figures.)

In what region of the beam is the internal bending moment constant, as measured from point A?
