The answer is A. The sample from a crime scene does not have enough DNA to perform forensics tests such as DNA matching. PCR -polymerase chain reaction - is used to amplify the DNA to required amount. Each cycle of PCR amplifies DNA two-folds
Answer:
In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell. ... In many synapses, the presynaptic part is located on an axon and the postsynaptic part is located on a dendrite or soma.
The function of the synapse is to transfer electric activity (information) from one cell to another. The transfer can be from nerve to nerve (neuro-neuro), or nerve to muscle (neuro-myo). The region between the pre- and postsynaptic membrane is very narrow, only 30-50 nm

The chemical composition of glycocalyx is sugar and protein.
<h3>What is the glycocalyx?</h3>
The envelope formed by <em>glycoproteins, glycolipids and hyaluronic acid</em> located in the cell membrane is known as glycocalyx. This component works as a <u>mechanical cell protection</u> thanks to its composition, it also allows <u>cell adhesion</u> and <u>hormonal reception</u> by giving it a suitable environment for this reception.
The glycocalyx is not only seen in eukaryotic cells, but also in prokaryotic cells or in bacterial cells. Each type of cell has its different conformation of the glycocalyx, this <em>depends on its individual need</em>.
Therefore, we can confirm that the chemical composition of glycocalyx is sugar and protein.
