I believe aluminum is the easiest material to recycle.

A rate of change in this case would refer to </span><span>the speed at which the respiration</span> is happening<span> over the measured period of time. G</span>raphically, is the slope of a line and that is why is easier to gather conclusions from a line graph instead of any other type.<span>

Answer:
In this given statement , the plastic base becomes negatively charged because plastic is an insulator . And the metal cup does not become charged because metal is a conductor.
Explanation:
<u>Reason behind , why plastic base becomes negatively charged -:</u> When a plastic base is rubbed with a dry cloth in the metal trophy, electrons are shifted from one material to the other. Thus, the substance that gains electrons (which is the plastic base) becomes negatively charged. thus , the plastic is an insulator , which causes charge (negative ) by rubbing.
<u>Reason behind , why the metal cup does not become charged -:</u> The metal cup is a conductor, and the surplus charge on the metal flows to the person who charges the cup and to the ground so that it is not charged. Thus, rubbing a metal can trigger hand\finger injury because metals generate excess heat in rubbing .
Strong base. Anything below seven is an acid while anything above it will be a base. Seven is Neutral because it is directly in the middle. <span />
