Answer:
a catalytic converter is device made up from metals like metals like palladium and rhodium to reduce the toxic gases emitted in the environment
Explanation:
Catalytic converter is an exhaust emission controlling device. It was made to reduce pollutants in air. Almost every automobile has a catalytic converter. It is present to completely remove the fuel that was not combusted and other toxic/dangerous compounds before they are let out in the environment.
If the catalytic converters are not used then the harmful compounds are released in the air and thus increasing air pollution and also decreasing the air quality for breathing in the surrounding environment.

Answer: What is expected to happen is that the secondary immune system acts immediately against the virus.
Explanation:
When a virus first enters our body, in order to defend itself, the body must first recognize what the antigen is in order to fight it through <u>antibodies</u>. Once it does it will keep a memory of it that it can use if this virus enters the body again. <u>This will be done through the secondary immune system</u>.
As the body already recognizes the antigen, it knows how to fight it immediately, generating a thousand times the amount of antibodies generated the first time.
Thanks to its memory cells, the virus will remain much less time in the body.
