Answer :
The answer is That percentage of composition of Zinc as determined said to be 19%, the percentage of iodine 81% and it shows that it is very close to accepted values by making calculations.
Explanations:
When iodine is dissolved in a strongly polar substance such as menthol. As the reaction is progressed, the color of the solution going from its initial color. Furthermore, after the reaction, small grey pallets supports the percentage between iodine reacted with the zinc. All the iodine reacted whereas portion reacted while the rest remained untouched.
Digestion and Absorption

Answer:
All life respires, or breathes. Respiration in mammals is similar to respiration in other air-breathing animals. Respiration extracts oxygen from the air, which is then used by cells. Respiration also carries waste carbon dioxide away from the cells. Although respiration depends on other systems, like the circulatory system, to take oxygen and carbon dioxide to and from cells, the respiratory system has the primary responsibility of bringing oxygen in to a mammal's body and sending carbon dioxide into the atmosphere.
