Collectively, the nerves of the gastrointestinal tract are referred to as: select one: a. hepatic nerves. b. peptic nerves. c. gastric nerves. d. enteric nerves.

The gastrointestinal tract is composed of the mouth, the oesophagus, the stomach, and the intestines.

Collectively, the nerves of the gastrointestinal tract are referred to as enteric nerves. Correct D

The enteric nervous system (ENS) consists of a mesh-like system of neurons that governs the function of the gastrointestinal tract.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

explanation:

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
