Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.
The correct answer is "transport proteins within the cell membrane pick up and release the minerals across the membrane".
Sodium and potassium travel in and out of cells with the help of sodium-potassium adenosine triphosphatase (or Na+/K+ ATPase). This is a transmembrane ATPase, meaning that it is an enzyme located in the cellular membrane of all animal cells. It works as a pump, by pumping sodium out of the cells while pumping potassium out of the cells.
<span>The answer is B. We require trees to breath. We would be stuck in an unfortunate situation without our woods. Trees expel carbon dioxide from the environment and discharge oxygen through a procedure called photosynthesis. Basically all creature life on Earth needs oxygen to inhale and woodlands assume a key part in the complex worldwide oxygen cycle.</span>
