Facilitated diffusion therefore allows polar and charged molecules, such as carbohydrates, amino acids, nucleosides, and ions, to cross the plasma membrane. Two classes of proteins that mediate facilitated diffusion are generally distinguished: carrier proteins and channel proteins.
They can enter your blood stream (via breathing/ingesting) and once in your bloodstream they can enter cells and mutate your dna, which can cause cancer/birth defects/ reproductive harm
Do you have a full detailed question? Or perhaps a photo of the question?
1. Osmosis
Recall that osmosis specifically refers to <em>water specifically</em> moving through a membrane in and out. In this case, water is moving out of cells through the cell membrane into the water.
2. Diffusion
Diffusion is the movement of molecules according to a concentration gradient. Because of this, diffusion is a form of passive transport because it does not require energy. In this case, oxygen is moving freely from the lungs into the bloodstream. This process does not take energy, and because oxygen is a small, non charged molecule, it can diffuse freely, therefore the process is diffusion.
3. Active Transport
The sodium pump is a prime example of active transport. Remember that when pumps are involved, it essentially means whatever is moving cannot move by itself, but rather needs force behind it, which is provided by the pump. Because sodium cannot simply move out of a nerve cell, this is a form of active transport.
Hope this is helpful!
Explanation:
dependent is what ur measuring, independent is the diff salt concetration
and the control group is what stays the same like the water or the plant. not sure, it's not rlly clear
