the parasympathetic nervous system stimulates the secretion of diluted saliva. The nervous center for this reflex is the superior salivatory nucleus in the pons for sublingual and submandibular glands(seventh cranial nerve-facial), and the inferior salivatory nucleus for parotid glands(ninth cranial nerve-glossopharyngeal nerve)
Living indicators are species that are sensitive to changes in the environment. For example air pollution can be monitored by looking at lichen, which are sensitive to sulphur dioxide in the air. The number of lichen at a particular location indicates how clear the air is. Similarly, mayfly larvae are good indicators for water pollution because they're sensitive to the concentration of dissolved oxygen in water.
Non-living indicators are things like satellites which can measure the temperature of the sea surface, weather stations that measure atmospheric temperature, rain gauges to measure rainfall, and dissolved oxygen meters to measure concentration of dissolved oxygen in water.
Answer – B (Electrons)
When atoms combine, their nucleons fuse to produce a new nucleus and interactions occur between their electrons, particularly the outer valence electrons. The interaction between the outer valence electrons of the combining atoms forms bonds between them.
