Answer: The carbon dioxide is the output and oxygen is the input of the Scuba apparatus.
Explanation:
The scuba apparatus is a life saving apparatus used by the sea divers. It recycles the exhaled gas and removes the carbon dioxide and compensates for the utilized oxygen gas before the diver is actually supplied with the gas for the purpose of breathing in a circuit. Hence, the carbon dioxide gas is the output and the oxygen is the input.

It is impossible for any sort of water to "expire". But, when in the bottle for to long, the plastic does become dangerous. The bottle begins to leak chemicals into the water. This doesn't make the water toxic, but it can alter the taste of your water.
Answer:
Radiometric dating methods
Explanation:
Absolute dating is the process of determining an age on a chronological or specified time scale in which events occurred in archaeology and geology. Absolute dating can be determined by using properties of the atoms that make up materials.
The most common method of absolute dating uses by geologists is radiometric dating methods which is based on the natural radioactive decay of certain elements such as potassium and carbon found in the rocks. By comparing the ratio of parent isotope with a known half-life to daughter product in the rock, the age of the rock can be determined.
The carbon-14 isotope is used in radiocarbon dating, but is only useful for measuring recently formed rocks in the geologic past. The decay of Potassium-40 isotope known as potassium-argon (K-Ar) method allows dating of materials that up to 1,000 billion years old.
