The hormone that stimulates the secretion of gastric acid is: MCQ with Answer and Explanation

Explanation:
Biological nitrogen fixation, performed by bacteria (Rhizobium, Azotobacter) and cyanobacteria, reduces N₂ to NH₃. Nitrification oxidizes ammonia to nitrates, denitrification returns N₂, ammonification releases ammonia from organic matter.

Explanation:
Transcriptomics studies the complete set of RNA transcripts (transcriptome) produced by the genome under specific conditions. It often uses microarrays or RNA-seq. Genomics is DNA, proteomics proteins, metabolomics metabolites.

Explanation:
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy (glucose) using carbon dioxide and water, releasing oxygen. It occurs in chloroplasts. Respiration releases energy from organic molecules. Transpiration is water loss. Chemosynthesis uses chemical energy (by some bacteria).
