The answer is benedict’s reagent. Benedict’s
test is used to detect reducing sugars in solution when heated. The color
change occurs from clear blue to a brick-red precipitate in the presence of the
reducing sugars. The cupric compounds in
the benedicts reagent react with the reducing sugars (enediols) produced from
heating of the reducing sugars in the presence of an alkali. Benedict's reagent is comprised of a mixture of sodium citrate, sodium carbonate, and
copper(II) sulfate pentahydrate.
Answer:
Transcription, mRNA (processing, transport, localization and stability), translation.
Explanation:
- Transcription is regulated in two levels, though chromatin regulation (methylation and acetylation) to loose or increase histone's affinity to DNA and through cis and trans elements such as promoters, enhancers, and silencers (cis) to active/deactivate and RNA polymerase and transcription factors and co-factors (trans).
- mRNA can be regulated using poly-A tails or 5'-caps to shorten or give them more time before they degrade, it could also be spliced to eliminate introns.
- In the translation stage, the regulation occurs during the initiation through a scanning procedure that ensures the 40s ribosomal subunit bind correctly to the untranslated portion of RNA

The DNA is condensed before replication in the form of chromosomes and then the chromosomes are divided.
That would be A.
Cells have specific receptors for different hormones that allow the intake of them.
