Answer:
False
Explanation:
Diffusion uses the concentration gradient that has been set up, this is a naturally occurring phenomena, and using a diffusion gradient some small particles can cross over the cell membrane. Some bigger or polar molecules require facilitated diffusion to move these molecules across the membrane.
Facilitated diffusion still uses the gradient for passive transport. This means that ATP is not used to transport molecules.
The reason that glucose will not move into the cell via passive transport is because there is a higher concentration of glucose inside the cell, meaning it needs active transport to move glucose (against the concentration gradient) into the cell.
Explanation:
It should be seen that perhaps the intensity of Ebony timber is greater than the concentration. This can drown if this is heavier than water, but that will floating whether it is not viscous than air.
Answer:
loses electrons and loses potential energy.
Explanation:
A reducing agent looses electrons in an oxidation-reduction reaction. Oxidation is defined as the loss of electrons.
Reducing agents are oxidized in an oxidation-reduction reaction. When a specie looses electrons, it also looses energy. Hence the answer given above.
<span>Sulfuric acid has the highest production levels of any chemical in both the US and the world. The US alone creates 37 million tons a year. It has many uses, but one of the largest is as fertilizer.</span>
