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.

1. Agriculture begins in some areas of Central America. Pottery is made in Mexico which is used to store food.
2. Starting in the Middle East, the Neolithic period starts to move into the Copper Age as copper tools replace stone tools. Eventually all groups will move towards tools made with either copper, bronze, and/or iron as people realize how useful the new tools are. The Neolithic Era will be remembered as the major transition from the hunting, gathering, and wandering groups to the agricultural communities and the domestication of animals.
3. More areas start practicing farming, including parts of Europe and then eventually England and Scandinavia. Houses are made with wooden sticks woven together and then covered with clay and mud. As more people live in villages, some forms of government develop.
Hope this helps!
