Agricultural chemicals is an example of a nonpit source of freshwater pollution
The answer is C, the sugar, as the D stands for deoxyribose
By sodium and potassium pump.
The sodium-potassium pump is observed in various cellular membranes. They are fueled by ATP, the pump moves potassium and sodium ions in reverse orientation, each against its concentration gradient. In a single cycle, two potassium ions are imported into the cell, and three sodium ions are extruded out.
These pumps are utilized to produce gradients of sodium and potassium ions. These gradients are used to proliferate electrical signals, which travel along the nerves.
<span>The speed of sound change as the sound of a boat engine moves down to the depths of the ocean The speed increases and then decreases as the temperature of the water increase. Sound do not travel faster in water than air due to the resistance. The salt and water molecules of the ocean cause interference for the sound wave to travel across it. It it had travel through air, then you can hear the sound of the incoming boat. But if it goes down into the water, and as you know it, going deeper into the water increases the pressure all the more that it muffles the sound of the engine of a boat. That is why it increases then decreases its sound as it goes down the ocean.
