Parietal cells are the epithelial cells which secrete hydrochloric acid and intrinsic factors. The cells are located in the gastric glands which are found in the linings of the walls of the stomach. The hydrochloric acid produced by the parietal cells helps in the conversion of the enzyme pepsinogen to pepsin during the digestion process.
Transfer = 10/100 of total energy.
<u>Explanation:</u>
Energy and matter is transferred from one organism to another by the process of food chain and food web. In food chain the organism of higher trophic level feeds on the organisms of lower trophic level. On feeding only 10% of the energy gets transferred to the organism of higher trophic level while the rest are being used in the metabolic processes and are produced as heat. This is called as ten percent energy transfer rule.
The mathematical representation of the transfer of energy is given as
Transfer = 10/100 of total energy.

Answer:
A new rock is produced that is different from the original rock.
Explanation:
During chemical weathering, a new rock is produced that is different from the original rock.
- Chemical weathering is the chemical decomposition of rocks to form sediments and soils.
- A large chunk of rock combines with water, air and other chemical materials.
- This cause chemical action and a new substance is produced.
- This process is known as chemical weathering.
Physical weathering is the breaking down of rocks into smaller fragments.
