Answers

Answered by deepgaurav821

Answer:

Human blood is red because of the protein hemoglobin, which contains a red-colored compound called heme that's crucial for carrying oxygen through your bloodstream. ... That's why blood turns bright cherry red when oxygen binds to its iron. Without oxygen connected, blood is a darker red color.
