The correct option is (A) Gastrin.

Stomach acts as an important organ in the process of digestion aiding both the mechanical and chemical digestion. Gastric glands are present in the walls of the stomach and help in the secretion of the gastric juice into the lumen of the stomach. The zymogenic cells or the chief cells of the gastric glands secrete the gastric enzymes and the parietal cells or the oxyntic cells secrete hydrochloric acid.

The gastric juice is an acidic digestive fluid containing the hydrochloric acid, digestive enzymes like pepsin, gastric lipase and renin, potassium chloride and sodium chloride. Secretion of gastric juice is regulated by the autonomic nervous system (peripheral nervous system that influcences the funtioning of internal organs) and hormones.

The hormone produced mainly in the stomach which regulates the secretions of gastric juice is the gastrin. It is a peptide hormone stimulating the secretion of hydrochloric acid by the parietal cells of the stomach. It also stimulates the chief cells to secrete pepsinogen which is the inactive form of the enzyme pepsin catalyzing the protein digestion.

Secretin is a hormone produced by the duodenum (part of small intestine) to stimulate the secretions of liver and pancreas. Pepsin is an enzyme helping in the digestion of proteins. Thus, gastrin is the hormone produced in the stomach regulating the secretion of the gastric juice.

Hey!

ANSWER:
The hormone that is produced mainly in the stomach and also regulates secretions of gastric juice is gastrin.

EXPLANATION:
Gastrin is a type hormone that is produced by the something known as g cells. These cells become activated once a person eats food and the food travels to the stomach. The hormone is then left into what is called the bloodstream. There it starts to have an effect on some of the other cells that are in the stomach. This allows the acid of the hormone to be entered in the stomach.

Hope this helps!

Nature vs Nurture debate.

Explanation:

Development in human is inborn.The stages of development is dictated and directed by expression of genes encoded by the DNA.Therefore physiological and biochemical interpretations of these DNA dictates is known as human development. it is a fixed mechanisms which is fastest at childhood,and progressively slower at advanced stage.Although environmental factors may influence this developmental stages, the exact mechanism of occurrence is constant and fixed.

Nuture concept believe that, human development is as a result of societal and cultural factors in the environment, and the progression of the development is due to the influences of theses factors on human perception of life. Thus Human development is acquired through life exposure and experiences.They are therefore dynamic, and not static, but fluctuates based on level of exposure in the environment.

However, both concept interacts with one another to ensure an holistic human development. Generally it is the interaction of the environment with genetic that explains the concept of natural selection and evolution of human race.
