Answer:
Prokaryotes do not have introns, eukaryotes have introns
Explanation:
Prokaryotes do not have introns, eukaryotes do. Introns are regions of DNA that are transcribed but not part of the final protein. They interrupt exons, which are the coding parts of the gene. These are only present in eukaryotes.
Introns need to be removed before the mRNA can be translated into the protein sequence. This occurs by a process called splicing. The splicing machinery binds the junction between introns and exons and excises the intron. The exons are then fused together to create the mRNA.
Other processing steps occur to the eukaryotic pre mRNA to prevent it from being degraded in the cell. This includes adding a cap to the 5' end of the protein, and adding a poly A tail to the 3' end. One these steps are complete, the eukaryotic mRNA is complete.
The prokaryotic mRNA undergoes transcription and translation simultaneously because it doesn't require these processing steps.

Explanation:
The Function of the Shoot System
The shoot system works closely in part to the root system of the plant. The shoots are able to absorb nutrients via the plant's different roots. The water and other nutrients that are taken in are shuttled up through the plant's vascular system located in the shoot
Answer : The molar concentration is, 
Explanation :
First we have to calculate the moles of protein.
Number of molecules of protein = 2 molecules
Avogadro's number = 
Now we have to calculate the radius.
Radius = 
Conversion used : (1 mm = 0.001 m)
Now we have to calculate the volume.
Conversion used : (1 m³ = 1000 L)
Now we have to calculate the molar concentration.
Thus, the molar concentration is,
