Answer:

The sample contains protein.

Explanation:

Biuret test is a test used to determine or assay for proteins in a solution. When the biuret reagent is added to a solution and it turns blue after 2 minutes, it means that the solution contains protein.

Benedict’s test is used to determine the presence of sugar (reducing sugar) in a solution. When it turns brick red, it means there is the presence of reducing sugar in large quantity.

From the question, since the solution turned blue on addition of Biuret  reagent and was also blue on addition of Benedict’s reagent (the reagent is usually blue), it means that the solution contained just proteins excluding reducing sugars.

Was reconstruction a success? <br><br> Please help
Vedmedyk [2.9K]
Though, like all things in life, it did come to an end, the resulting outcome has been labeled both a success and a failure. When Reconstruction began in 1865, a broken America had just finished fighting the Civil War. So yes, reconstruction was a success.

Answer: Social constructionist theory.

Explanation:

The social constructionist theory states that any social movement is an interactive, symbolically marked, a product of a negotiation process that requires participants, contestants, and spectators. Research conducted under this perspective will focus on the way problems are framed and named by people, depending on their own framework.
