Answer:
A positive result.
Explanation:
Biuret test is a test performed to check whether proteins are present in a given sample or not. If the solution changes its colour to violet then it means that the sample contains proteins. If the colour is not changed to violet, then the result would be negative and protein would not be present in the sample.
Steaks contain a rich amount of protein. Hence, when Biuret test is performed for a steak solution, the results will be positive. The steak sample would change colour to violet.
