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.
A unicellular organism must perform all functions necessary for life. A multicellular organism has specialized cells, tissues, organs, and organ systems that perform specific functions.
Answer:
In the physical sciences, subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles.
Explanation:
Answer:
C
Explanation:
Sugar, which is a product of the photosynthetic process of green plants can be converted to glucose (a simple carbohydrate). Enormous amount of these glucose molecules can be linked together to form a complex carbohydrate called cellulose, which is a polysaccharide because it is made up of a long chain of glucose molecules. The cellulose is ultimately used to build the cell wall of plants.
Anabolism is the production of a complex molecule by a living organism from a much simpler one. Since, cellulose is produced by the building up of glucose molecules, the process can therefore, said to be anabolic
D is the correct answer i think.
