<h2>Receptors for hearing are in the cochlea; receptors for balance are in the vestibule.</h2>
Hope this will help....
They are used for them to adapt to the environment
The color and texture of both things can be used for the upper middle and lower layers of the earth
The log will float on the water because his density is lower than the liquid, so it will stay at the top due to Archimedes' principle.
<span>Archimedes' principle is a physical law that describes the upward force (the vertical thrust) experienced by any body immersed in a fluid (liquid or gas). This force is strongly related to the density of both the fluid and the body.

You can try the experience at home, by using an object that has a lower density than the water like the sunflower oil, you will see that it will stay at the top of the water too.
When using the forced-choice procedure in measuring odor detection thresholds, the experimenter should separate trial by about 30 second Forced force method an experimental methods which help to obtain threshold.For a single interval and forced choice method there they are at least three procedure for collecting data.
