Katena32 [7]

Answer:

only sympathetic fibers can regenerate accurately

Explanation:

Neuroregeneration is a complex biological process associated with the regrowth and/or repair of nervous tissues. This process depends on the type of nerve tissue and how seriously the nerve was injured. The autonomic nervous system, also known as the autonomic nervous system (ANS), is part of the peripheral nervous system (PNS) that is responsible for regulating involuntary physiological processes. The PNS contains two basic divisions: sympathetic and parasympathetic. The sympathetic fibers innervate tissues in nearly all the organ systems and they are responsible for regulating homeostatic processes (e.g., heart rate). The sympathetic nervous system is formed by nerves from the thoracic and lumbar segments of the spinal cord. These autonomic nerves can regenerate after injury in order to reinnervate target tissues (e.g., after chronic cardiac ischemia).

Answer:

There are no options in this question but generally a sample of DNA can be increased;

By using Polymerase Chain Reaction (PCR) technique.

Explanation:

This question describes the application of making molecular biology to solving a crime problem; a branch called forensics. In this case where an insufficient small amount of DNA sample was recovered from the blood in a crime scene, the polymerase chain reaction technique, commonly known as PCR can be used to increase the DNA sample.

In the 1980's, a molecular technique used to amplify part of a template DNA strand to produce several copies of it, was invented by Kary Mullis and his colleagues. This amplification refers to the numerical increase in the number of DNA sequence.
