Answer:

It acts as a filter to prevent as much germs, or chemicals/substances, as possible from entering your immune system through your breathing. This is whether you're in a lab or in a grocery store with a pandemic going around. Not only does it protect you but it also protects those around you by filtering any germs you may already have in your system and preventing them from passing on to another person. That is why you should always wear your mask over your mouth <em>and</em> your nose.

Explanation:

Hope this helps. Have a great day. May it be filled with joy and happiness. Please, stay safe and wash your hands.

Which of these charges has the greatest magnitude
Natalka [10]

Answer:

magnitude means absolute value, so the one that is greastest, like |-7| and |4| even id |-7| is a negative number, but it is still the one farthest away from 0, so |-7| is greater than |4|.

That is the way to find the greatest magnitude, but because I don't know your numbers so I can not answer your question, but this is the way to solve for it.

HOPE THIS HELPS!!!!!!!!!( IF IT DOES <u><em>PLEASE MARK ME AS BRAINLIEST )</em></u>

The drugs Prilosec and Nexium both contain the same active ingredient. Nexium contains a single enantiomer, but Prilosec is a ra
Softa [21]

Answer:

both drugs will be equally effective

Explanation:

A racemic mixture is a substance that contains a 50/50 mixture of the (+) and (-) enantiomers of an optically active compound.

It is important to note that even if a drug occurs as a racemic mixture, only the biologically active enantiomer will interact with the substrate on which the drug acts. The other enantiomer present is just irrelevant. Similarly, its presence does not affect the biological activity of the active enantiomer.

Hence, both Prilosec and Nexium are both equally effective.
