The scientific meaning of salt is an ionic compound that is formed when an acid and a base reaction take place and is neutralized.
The common meaning of salt (table salt) is specifically the organic mineral of sodium chloride (NaCl) and is digestible.
Ionic salts are often not digestible (or not commonly digested, anyway)
Body temperature is controlled by a negative feedback control system.
What is negative feedback?
In biological systems, a type of control known as negative feedback occurs when a process's output lowers its own stimulus. A common regulation mechanism in many biological responses is feedback. The body may regulate numerous aspects of its internal environment by permitting particular routes to be switched on and off. This is like turning a switch. Feedback enables a pathway's output to operate a switch. Negative feedback, often known as a "negative feedback loop," happens when a pathway's end product disables the corresponding metabolic step.
In order to maintain body temperature, the hypothalamus reacts to this information by directing nerve impulses to effectors. For instance, the hair erector muscles tighten up if we get too cold. As a result, a layer of air is trapped near to the skin, raising the skin hairs. Systematic negative feedback regulates body temperature.
<u>Thus the </u><u>hypothalamus</u><u> is the vital organ for this system.</u>

Answer:
Convection is the process of heat transfer in which hotter and therefore less dense matter floats to the top, while cooler and therefore more dense material sinks to the bottom to absorb heat.
Explanation:
Convection is one form of heat transfer; other forms include conduction and (heat) radiation (not exactly the same as the kind uranium emits).
This form of heat transfer is characterised by a use of current in a liquid, in which the sinking and rising create a current which has a shape of a loop.
This requires an outside source of heat, since to sustain the current, once the heated fluid rises up, it must lose heat to the environment to sink, but to rise it must gain heat again.
Answer:
The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
When a syringe is inserted into the flask containing methane gas the plunger of the syringe is raise up. This led to filling of the syringe with the gas.This relate to Charles law which explain how gas expand with increase in temperature.
