If an individual is a carrier of an infectious disease, he is BOTH ASYMPTOMATIC AND INFECTIVE .
An asymptomatic and infective carrier refers to a person, who is a carrier of a disease or has a disease causing infective agent in his system [that is, the person is infected with an infectious disease] but who is not showing any symptom of the disease. Carriers are not usually affected by the disease concerned but they can easily transmit it to other people.
They are called natural recyclers because they naturally break down dead and decaying matter. I hope this helps!---
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.
