Answer:Cyandie turns a deep blue when certain chemicals are added
Explanation:
Cyanide seizes every form of oxygen from the body, leading to the death of cells in the human body, as cells need oxygen to be functional, liquid forms of cyanide can be absorbed through the skin, and when they do, they interfere with cellular respiration, making it difficult for the body tissues to use oxygen. Cyanide is more harmful to the heart and brain, which are major users of oxygen in body organs.
