The correct option is D.
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.

Answer:
carbon is the main element
Explanation:
Organic compounds make up the cells and other structures of organisms and carry out life processes. Carbon is the main element in organic compounds, so carbon is essential to life on Earth. Without carbon, life as we know it could not exist.
Answer:
We turn now to transcription in eukaryotes, a much more complex process than in prokaryotes. In eukaryotes, transcription and translation take place in different cellular compartments: transcription takes place in the membrane-bounded nucleus, whereas translation takes place outside the nucleus in the cytoplasm.
Answer: The heating process and the freezing process
Explanation:
When ice is heated up and begins to melt, the matter that makes up the ice (water) is infused with energy. The energy causes the ice to melt into a liquid and then into a gas. As the energy becomes greater and faster, the heat is more effective on melting/evaporating the ice/water.
When water is put in the freezer to chill, the cold air causes the energy cells to slow down, causing air to condense into water, and water to freeze into ice.
These are some examples that are easier to understand than other concepts, but there are many more of these occurrences in the world!
