Question

what make the blood look red​

Answer 1

Explanation:

Blood is red because of the hemoglobin inside our red blood cells.

Hemoglobin is a protein that forms a complex with iron molecules and together they transport oxygen molecules throughout the body. Iron has the property of reflecting red light and because there is so much iron in our blood, blood looks red.

Hence Haemoglobin makes the blood look red.

Answer 2

The presence of red blood cells in the blood makes the blood look red in colour.
