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 .
The snail would release Carbon Dioxide like humans do.
Answer:
A green ball is used for the sets which were then replaced with CGI with a human
Respiration is the chemical reaction that break down nutrient molecules in living cells to release energy .
in humans and other living organisms except plants, our cells need energy ATP for muscle contraction and for cell division to repair damaged tissues and growth ,also for active transport which involves movement of molecules across a cell membrane against a concentration gradient.
Answer:
Transporte activo, El Transporte pasivo es una gran estrategia para el movimiento de que la célula debe hacer es quedarse allí y dejar que las Moléculas se difundan a su interior. Por ejemplo, supongamos que tenemos una alta concentración de iones y sodio en el espacio extracelular(gracias al gran esfuerzo de la bomba sodio-potasio).
