Which one of the following processes does not occur to excess neurotransmitters in the synapse
svlad2 [7]

This question is incomplete because the options are not given; here is the complete question:

Which one of the following processes does not occur to excess neurotransmitters in the synapse?

A. Break down or digested into inactive fragments.

B. Collection by scavenger vesicles left over from the neurotransmitter release.

C. Drifting away from the synapse via diffusion.

D. Reuptake within the pre-synaptic neuron.

The answer to this question is B. Collection by scavenger vesicles left over from the neurotransmitter release.

Explanation:

The word synapse refers to the neurological structure that allows the transmission of signals or information between neurons. This process occurs through neurotransmitters, which are the molecules or substances with the messages.

Moreover, in this process, there can be in some cases excess. In this situation, the body reacts to this excess by degrading or breaking down the extra neurotransmitters, eliminating it through diffusion, or even reabsorbing it (reuptake). In this context, all are processes that occur due to excess neurotransmitters except collection by scavenger vesicles because in most cases neurotransmitters are simply absorbed or eliminated but there are not specialized scavenger vesicles that collect them.

Answer:

Dispersion of white light by a prism

Explanation:

When white light is passed through a prism, the white light separates into its component wavelengths which are:

Red

Orange

Yellow

Green

Blue

Indigo

Violet

Together, all of these wavelengths constitute the spectrum of white light.

Hence, the dispersion of white light shows that each color of visible light has a specific wavelength.
