The answer is c02 regulation, the carbonic acid bicarbonate buffer regulation, the H+ regulation and gas exchange. The following regulations are all completed through the circulatory, excretory and respiratory systems which is part of one huge function that is called homeostasis. Homeostasis is the predisposition to repel alteration in order to uphold a even comparatively constant internal situation.
The right answer is A rapid temperature increase will give a melting point range that is too high.
The melting point is determined in a capillary tube. it means the temperature at which the substance is completely melted, indicated by the disappearance of the solid, will not differ by ± 4 ° C from the given value, unless otherwise indicated.
The following technique can be applied to determine the melting point:
Grind some amount of substance in a small mortar. Place in a vacuum desiccator containing silica gel or phosphorus pentoxide and allow to dry for 24 hours at room temperature (unless another method of drying is indicated in the test protocol) . Introduce the substance into a dry capillary tube 1 mm inside diameter to form a column about 3 mm high. Heat the melting device to a temperature 5 to 10 ° C below the expected melting temperature and adjust the heating so that the temperature of the enclosure rises by approximately 1 ° C per minute. Introduce the capillary tube containing the substance into the heated chamber and note the temperature at which the agglomerated substance becomes completely transparent; this temperature constitutes the melting point.
