Answer;
Oxygen or an oxidizing agent to receive electrons must be present for oxidation to occur in chemical reactions.
Explanation;
Oxidation entails the loss of electrons from these molecules, causing them to become unstable and highly reactive and leading to their eventual reaction with and damage of cell components such as membranes.
-In redox reaction; The ion or molecule that accepts electrons is called the oxidizing agent; by accepting electrons it causes the oxidation of another species. Conversely, the species that donates electrons is called the reducing agent; when the reaction occurs, it reduces the other species.
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.
Answer:
<em>Moving</em><em> </em><em>of</em><em> </em><em>fan</em><em> </em><em>is</em><em> </em><em>convection</em><em>.</em>
<em>The faster moving air from the fan displaces the warmer air that is in direct contact with our skin. This enhances the rate of convective heat transfer, which means we feel cooler.</em>
