Question

instructions this quick quiz covers information from the labster biuret lab simulations. this quiz is untimed but can only be completed once. you may want to go through the simulation once and then go back through a second time when completing the quiz. multiple attempts not allowed. this test can only be taken once. force completion this test can be saved and resumed later. your answers are saved automatically. question completion status: question 1 10 points save answer the biurets reagent will stay blue if mixed with something that does not contain a protein such as water true false question 2 10 points save answer we need to add heat to the protein and biuret reagent for the reaction to work true false

Explanation:

1. Biuret reagent is used to detect proteins. In the absence of proteins (such as in water), it remains blue. So, the statement in Question 1 is true.
2. The biuret - protein reaction is a simple color - change reaction at room temperature and does not require heating. So, the statement in Question 2 is false.

Answer:

Question 1: A. True
Question 2: B. False
