Answer: Around the 5th century bc, the Persians under Cyrus the Great had rapidly expanded their domain. By the time of Darius I, the Persian empire covered most of southwest Asia and Asia Minor, reaching as far as the easternmost boundaries of Europe. The Persians demanded tribute and respect from all they dominated. The Greek cities in Asia Minor eventually decided to throw off the Persian yoke. Through those revolts, the assistance of the Athenians and the ensuing Battle of Marathon, the wheels had been set in motion to end Persian domination.

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.
