The eukaryotes are the organisms that contain the genetic material (DNA) inside the membrane enclosed nucleus. These organisms contain membrane bound cell organelles, such as mitochondria, Golgi apparatus etc. as opposed to the prokaryotic organisms that contain no membrane bound organelles and no nucleus. The presence of enclosed nucleus and membrane bound organelles helps in determining that the cell is Eukaryote, but the presence of cell wall will be of no help as both the prokaryotes as well as eukaryotes contain cell wall.
Hence, the correct answer is 'cell wall'.
The correct statement regarding a chemical synapse is sodium ions enter the axon terminal to signal release of neurotransmitters i.e., option B.
<h3>What is chemical synapse?</h3>
Chemical synapses are links created by two neurons or a neuron and a non-neuronal cell (muscle cell, glandular cell, sensory cell).
The synaptic complex is the basic non-reducible unit of each chemical synapse, representing the bare minimum for efficient chemical synaptic transmission.
The correct statement regarding a chemical synapse is sodium ions enter the axon terminal to signal release of neurotransmitters.
Thus, the correct option is B.
