<em>The autonomic nervous system is a section of the peripheral nervous system that specializes in the regulation of various body processes that requires no efforts. </em>
The system operates by collecting information from the external environment and the body of living organisms. It is further divided into 3 sub-sections according to their specialization namely; the sympathetic, the parasympathetic and the enteric nervous system
Answer: such involuntary functions are governed by the Autonomic nervous system
Explanation:
It is the duty of the autonomic nervous system to regulate certain involuntary actions in the human body such as blood-vessel movement, heart rate, breathing, digestion, urination, sexual arousal, pupillary responses, secretion of body fluids like saliva and sweat, control of body temperature, emotional responses etc.
The Autonomic nervous system is made up of two components which does work in opposition to each other. These components are - The Parasympathetic nervous system and the sympathetic nervous system. The later is the one that is responsible for our response to danger (flight-or-fight responses) and the former is responsible for maintaining normal body functions. It also helps in bladder control and slowing down of heart rate.
For mitosis, the DNA content of the daughter cells and the mother cell will always be identical. Since the number of cells have doubled, so has the DNA. The 16 chromosomes in the mother cell will be duplicated, then the duplicates split and evenly divided into the daughter cells. The 16 chromosomes in each daughter cell will be non-duplicated at first.
Because the paleontologist recovered only a bit of tissue and it is very old, it is very likely that the DNA in the sample is very small and part of it is degraded. Anyway, the paleontologist must first amplify the DNA sample to obtain many identical copies of the specific region of the DNA they want to compare. the above is done through a polymerase chain reaction (PCR).
