If you take a bite of something that is highly unappealing (for example meat that tastes rotten) what is the response of the salivary glands? what does this tell us about the regulation of digestive enzyme secretion from the salivary glands?

The salivary glands are monitored by the autonomic nervous system. The smell, sight, or taste of the food instigates the discharging of saliva from the salivary glands. Thus, if an unappealing food is put in the mouth, the sympathetic nervous system gets stimulated and the discharging of saliva ceases. This demonstrates that the monitoring of digestive enzyme secretion from the salivary glands is not voluntary and is controlled by autonomic nervous system.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
