If Polaris were to go supernova today, no one currently on Earth ever know it happened because it would take 434 light years to reach the Earth
Explanation:
The Polaris or the North Star that we can see at the North Pole of the Earth in the night historically dates back to 434 years in the past. If the Polaris becomes a supernova or if it dies now, it will take 434 years in the future from now to know about it.
This is simply because ‘one light year is the distance traveled by light in one year’. Hence currently, one cannot know about what happened to the Polaris supernova even if it happens now.
The answer to your question should be the second option
Enzymes break up water or H2O into electrons, H+ ions, & oxygen atoms. Electrons replace the "highenergy" electrons that were lost in the electron transport chain.<span>Oxygen is released and the H+ ions are also released. - So the first one would be A. splitting of water or H2O
and the second one is B :)

Answer:
Amino acids are the building blocks of life and are encoded by DNA. Enzymes and structural proteins are made of amino acids, and are used as precursors for other important biomolecules in the body. In addition, many different industries ranging from pharmaceuticals to the food industry rely on amino acids.
