Answer:
The three main domains into which the organisms are classified are archaea, bacteria and eukarya.
Archaea : The archaea is more closely related to eukaryotes. Although they have bacteria like metabolism and have 70'S chromosomes but shows presence of introns and shows similar molecular mechanism like replication, transcription and translation similar to eukaryotes. These are found in the extreme conditions as well.
Bacteria: The bacteria have circular DNA with 70'S ribosomes. The cell membrane has ester linkage and no nucleosome formation occur in bacteria. The transcription and translation are coupled together with no further modification.
Eukarya: The eukaryotes have linear DNA with 80'S ribosomes. The cell membrane has ether linkage and proper nucleosome fprmation occurs in eukarya. The transcription and translation occurs separately in the distinct compartments and further modification occurs.
Glycemic Index is a measurement associated with observing the effect of carbohydrate on an individual's blood glucose (or blood sugar). Specifically the index is utilized when there is a rise in an individual's blood sugar after 2 hours of consuming food. Due to the expected high level of blood sugar, GI can also be used to assess Insulin response to store the excess blood glucose from the blood into body cells to organs such as the Liver. Ultimately, blood glucose are stored in the liver as glycogen, a form of energy reservoir.
They provide the immune system with "memory" against previously encountered pathogens.
T memory cells are necessary for protective immunity against invading pathogens
Ribosomes perform protein synthesis
