Answer:
Adenosine.
Explanation:
Adenosine is a neurotransmitter that is created in the brain and when it binds to the adenosine receptors, it slows down nerve activity and it creates a sensation of drowsiness.
<u>Caffeine</u> looks like adenosine to the receptors, therefore, when we have caffeine, <u>it binds to these receptors and there is no room left for the adenosine to bind</u>. However, the caffeine doesn't slow down nerve activity but, in the contrary, it speeds it up.
Therefore we can tell that caffeine blocks the receptors for the adenosine thus promoting wakefulness.

Answer:
Its translation the third one.
Explanation:
This process is when mRNA comes out of nucleus from nucleus pores and goes to free ribosomes or RER ribosomes. Then the mRNA enters ribosome. each three codes on mRNA is a code of amino acid. then an amino acid chain will be produced.
This chain will fold until it gets to its fourth structure. At last the protein is produced.
The senthesis and replication are not related to protein production.
Its related to cell cycle.
Transcription happens inside nucleus when RNApolymraze transcripts a copy of one strand of DNA
What it makes is mRNA.
Hope you understand.
