Natural selection is where positive traits survive more, allowing those to become more common. Mutation is where radioactivity changes genes in a random way. Natural selection allows positive mutation to become more common. Adaptation is where natural selection works for a species specifically more a new habitat.

A hormone released in the small intestine that stimulates the pancreas to release digestive enzymes and the gallbladder to release bile is known as Cholecystokinin.

Hormones play a huge position for your normal functioning. They manage heart rate, sleep cycles, sexual feature, and replica. Your metabolism, urge for food, growth and development, temper, strain, and body temperatures are all suffering from hormones.

Cholecystokinin is secreted by using cells of the upper small gut. Its secretion is stimulated by using the advent of hydrochloric acid, amino acids, or fatty acids into the belly or duodenum. Cholecystokinin stimulates the gallbladder to settlement and launch stored bile into the gut. Cholecystokinin (CCK) is produced more often than not inside the duodenum and the jejunum. The physiological roles of CCK are the stimulation of pancreatic secretion and the contraction of the gall-bladder. Secretin and CCK are peptide hormones secreted via the endocrine cells inside the gastrointestinal tract. Secretin stimulates the secretion of water and bicarbonate ions from the pancreas, while CCK stimulates the synthesis and secretion of bile juice and pancreatic enzymes.

A part of an mRNA has the sequence CCG. Which change to this sequence
Flauer [41]

Answer:

A single nucleotide changes in CCG which will result in missense mutation can be many possibilities.

Explanation:

Missense mutations  

CCG codes for Proline amino acid

• Mutation in first nucleotide codes for  

 UCG specifically encodes Serine

 ACG specifically encodes Threonine  

 GCG specifically encodes Alanine                              

                                                                                      Missense mutation  

• Mutation in second nucleotide specify for coding

 CUG specifically encodes Leucine

 CAG specifically encodes Glutamine  

 CGG specifically encodes Arginine

• Mutation in Third Nucleotide will not result in missense mutation because any point mutation in third nucleotide of codon will encode same amino acid i.e Proline.
