Membrane transport refers to the mechanisms by which solutes cross the plasma membrane, but there are additional prokaryotic cell structures through which a solute would pass when entering or exiting a cell. sequence the path of a solute from the external environment to the cytoplasm of a prokaryotic cell.

From the external environment of a prokaryotic cell, the solute will then go to the capsule, then enters in the rigid layer of polysaccharides located outside the plasma membrane which is the cell wall, then goes to the plasma membrane, and finally reaching the cytoplasm.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

the answer is yes, they are born/created, then they grow to their limit then produce offspring, then die.
