Answer:The Law of Conservation of Mass states that mass is conserved in physical and chemical changes. Students explore this concept by taking initial masses, making predictions, and finding final masses of physical and chemical changes. Students observe water changing from ice to a liquid, a piece of cardboard being cut up, salt dissolving in water, Alka-Seltzer reacting in water, and water's physical property of cohesiveness being disrupted by soap.

What is the function of synaptic vesicles inside axon terminals? what is the function of synaptic vesicles inside axon terminals
Igoryamba

The correct answer is option (D) store and release neurotransmitters.

The function of synaptic vesicles inside the axon terminals is to store and release the neurotransmitters. A synapse refers to the junction between the two neurons which transmit the nerve impulses by the diffusion of a neurotransmitter. Synaptic vesicles ar important for the transmission or the conduction of the nerve impulses as they store and release the neurotransmitters.

These neurotransmitters are the chemicals that transmit an impulse between two neurons or a neuromuscular junction. A neurotransmitter is released by the synaptic vesicle of one neuron into a region between the two neurons called the synapatic cleft. From here, it reaches the neurtransmitter receptors present on the target neuron, thus conducting the impulse. Examples of neurotransmitters include the epinephrine, histamine, acetylcholine and others.
