Please help! What is the structure labeled with the question mark?
a. Motor neuron with synaptic terminal
b. Synaptic vesicle with neurotransmitter
c. Receptor protein with action potential
d. Motor end plate with deactivation enzyme
Answers
Ans.
The given diagram represent chemical synapse, which is defined as biological junction between two neurons and is responsible for the exchange of neural signals. The structure labeled with question mark is synaptic vesicle. The synaptic vesicles are small sac like structures that contain neurotransmitters. These neurotransmitters are released by these vesicles through expcytosis and bind to receptors present in another neuron.
Thus, the correct answer is option b). synaptic vesicle with neurotransmitter.'

The structures help both plant and animal cells meet the challenges of life is nucleus and cell membrane. Thus, option B is correct.
What is nucleus and cell membrane?
Nucleus is the main cell organelle and the main function of the nucleus is to control and coordinate all the function of the cell. Nucleus is known as the brain of the cell and it has been present in the center of the cell. The color of the nucleus is black in color.The main function of the cell membrane has to keep away the toxic material out of the cell.
Cell membrane has been defined as a wall that differentiate and protect the inner structure of the cell from the outer environment. Nucleus is known as the brain of the cell and it has been present in the center of the cell. The color of the nucleus is black in color.The main function of the cell membrane has to keep away the toxic material out of the cell. The cell membrane that contain the channels as well as receptors that give the permission to only selective permeable membrane to enter into the cell.
Therefore, The structures help both plant and animal cells meet the challenges of life is nucleus and cell membrane. Thus, option B is correct.
