Answer 2

The human blood is red in color, because of the presence of hemoglobin.

▪︎Human blood is red because hemoglobin, which is carried in the blood and functions to transport oxygen, is iron-rich and red in color.

Did you know !?

▪︎Octopuses and horseshoe crabs have blue blood.

▪︎This is because the protein transporting oxygen in their blood, hemocyanin, is actually blue.
