The cell membrane is composed of a phospholipid bilayer.
The cell membrane is primarily composed of a mix of proteins and phospholipids
Phospholipids are a major component of cell membranes. They a head and a tail. The head is hydrophilic (attracted to water) and the tail is hydrophobic (repelled by water).
They form a bilayer in which their hydrophilic heads face the aqueous cytosol and extracellular fluid while their hydrophobic tails face away from the cytosol and extracellular fluid.
The lipid bilayer is semi - permeable
The correct answer is option C, that is, the Operons afford the organism the opportunity to simultaneously monitor the transcription of multiple genes, whose products are active in the same process.
The genes, which correspond to a particular metabolic procedure are usually under the control of a single promoter in a bacteria. This is known as Operon that assists in monitoring the expression of genes taking part in the similar metabolic procedure.

Answer:
Scientists have discovered what they say could be fossils of some of the earliest living organisms on Earth. They are represented by tiny filaments, knobs and tubes in Canadian rocks dated to be up to 4.28 billion years old.
