Answer:
The entry of food into the stomach.
Explanation:
Gastric secretion is triggered by the act of eating which is called as reflex phase and the entry of food into the stomach called a gastric phase. The entry of the food particles into the small intestine also helps to control the secretion of gastric called an intestinal phase.
The secreted fluid in the small intestine contains some ions, acids, etc such as pepsinogen, intrinsic factor, bicarbonate, hydrochloric acid, and mucus. The reflex phase or cephalic phase helps to stimulate parasympathetic neurons that release acetylcholine chemical, then it produces the higher secretion of gastric juice.

I am going to give you the material so that you can be your doubt but I will not solve it because that is the basis of your learning that you react to what you are reading
In Mendel's "Experiment 1", pea plants with smooth seeds intersect with pea plants with rough seeds. (smooth seeds is the dominant feature). Mendel collected the seeds of this cross, the plants and obtained the F1-generation of plants, let them self-pollinate to form a second generation, and analyzed the seeds of the F2 generation. The results they obtained; And the ones you would predict in this experiment are:
Guide
F1-generation plants
Mendel crossed SS (smooth seeds) with ss (rough seeds.)
All the gametes of parents smooth seeds, have the allele S (dominant) and all the gametes of parents rough seeds have the allele s (recessive). All the plants of the F1 generation will affect the Ss genotype (heterozygous), and all the seeds smooth seeds.
Generation-F2 plants
Mendel let the F1-generation plants self-pollinate to form a second generation and analyzed the seeds of the resulting F2 generation.
F2 generation
All F1 hybrid plants have the Ss genotype and all are smooth (dominant characteristic). Recessive alleles are secreted during gamete formation. As a result, one in four possible combinations in F2 generation plants will have the recessive homozygous genotype (ss).
