The biosphere is made of different kinds of matter. Which substance is an
Sedaia [141]

Salt is the Inorganic matter.

Option D.

<h3><u>Explanation:</u></h3>

Organic matters are defined as those compounds of carbon expect the carbonates, bicarbonates, cyanides etc. These compounds were primarily thought to be produced only from the living organisms and were unable to be produced in laboratory. But later they were being produced in laboratory too.

Inorganic compounds are all the compounds except the organic ones.

Here, in the question, we see the compounds -

Protein - it's the polymer of amino acids which contain carbon, and isn't carbonates or bicarbonates, cyanides etc.

Carbohydrates and sugars are also similar to proteins which contain carbon and isn't the exceptions. So they are also the organic compounds.

But salt, commonly table salt is sodium chloride which doesn't contain carbon, so is Inorganic.

How does prokaryotic transcription and translation differ from these processes in eukaryotic cells?
daser333 [38]

A

Explanation:

The genome of prokaryotes has no introns hence their mRNA does not need splicing like in eukaryotic cells. Also, because the genome of prokaryotes is not delimited from the cytoplasm by a nuclear membrane, ribosomes can attach to the elongating mRNA during transcription and begin translation. Therefore translation of mRNA occurs concurrently with transcription which cannot happen with eukaryotic cells.

In the nucleus of eukaryotic cells, transcription results to a nascent mRNA which is spliced into a mature mRNA.The mature mRNA has to travel outside the nucleus to the cytoplasm to be translated by ribosomes.
