Explanation:
Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. And the parts of the brain involved in motor control lose cells over time.
Researchers found that the brain's response time begins to decline at age 24. The descent is a slow, but nonetheless, steady one.
The number of electrons in the outermost shell of an atom
The answer is mRNA (messenger-RNA). In most eukaryotes, transcription occurs by firstly creating a primary

processed into a pre-mRNA that later becomes a mRNA
by removing introns. Processing of the RNA also includes
polyadenylation and 5’ capping.
