"The process of assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure [goid 6457] [pmid 10802661] [evidence TAS]; The process whose specific outcome is the progression of a male gamete over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell [goid 7286] [evidence IEA]; The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood [goid 7507] [pmid 10802661] [evidence TAS]; The series of events required for an organism to receive an olfactory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Olfaction involves the detection of chemical composition of an organism's ambient medium by chemoreceptors [goid 7608] [evidence IEA]; The process whose specific outcome is the progression of the gonad over time, from its formation to the mature structure. The gonad is an animal organ that produces gametes; in some species it also produces hormones [goid 8406] [pmid 10802661] [evidence TAS]; The assembly of a flagellum. In bacteria, this is a whiplike motility appendage present on the surface of some species; in eukaryotes, flagella are threadlike protoplasmic extensions used to propel flagellates and sperm. Flagella are composed of flagellin and have the same basic structure as cilia but are longer in proportion to the cell and present in much smaller numbers [goid 9296] [evidence IEA]; The assembly of a sensory cilium, a primary cilium found on sensory neurons that contains an a 9+0 axonemal arrangement of microtubules [goid 35058] [evidence IEA]; Behavior that occurs predominantly, or only, in individuals that are part of a group [goid 35176] [evidence IEA]; Any process preventing the degeneration of the photoreceptor, a specialized cell type that is sensitive to light [goid 45494] [evidence IEA]; A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus [goid 50896] [evidence IEA]; The series of events involved in the perception of sound in which a sensory mechanical stimulus is received by a cell and converted into a molecular signal. Sound is picked up in the form of vibrations [goid 50910] [evidence IEA]"
