Because they are used to make semiconductors. The reason why semiconductors are made out of metalloids is that heat and electricity don't travel as fast through metalloids as they do in true metals therefore protecting from a possible overheat or a fried circuit board.
When we say independent variable, this is the variable in an experiment that is being controlled in order to come up with an answer of a certain problem. In the given scenario above, the independent variable is the sugar consumption. This is the variable that is being controlled in order to know the effects (dependent variable). Hope this helps.
It is electrons because they are in the outermost shell of an atom that reacts with other atoms.<span>
