Neurotransmitters are broken down by enzymes in order to avoid over-stimulation of a neuron and to allow for the transmission of impulse another impulse by the neurons.
<h3>What are neurotransmitters?</h3>
Neurotransmitters are chemical substances which are released at neuronal ends and which help transmit sction potential from one neuron to another.
After the transmission of impulse between the neurons, neurotransmitters ate broken down by enzymes.

It is known as structurlism
<span>Only one sperm normally fuses
with an egg because if more than one sperm fuses, through a process
called polyspermy, development of the zygote usually stops.
</span>
<span>Fertilization of one egg by
two sperm is possible, but the resulting zygote is almost never viable
because such a zygote would have three sets of chromosomes instead of
the normal two. This condition, called triploidy, is usually
incompatible with life. Those rare triploid infants that do survive to
term have severe and multiple birth defects and rarely live more than a
few days. </span>
Answer:
A. stratified squamous epithelium; absorption
Explanation:
Stratified squamous epithelium are composed of multiple layers of cells which rest on a basement membrane. Superficial layers are made of squamous cells and underlying layers can also be made of cuboidal or columnar cells.
Stratified squamous epithelium is generally present in area where there is frequent physical or chemical abrasion. It protects the underlying structures from the stress. Hence, it is found wherever the body comes in contact with the outer environment like skin, digestive system and respiratory system. It also prevents water loss and desiccation.
