Answer:
Diffusion is the net movement of any substance from a higher concentration region to the lower concentration region. It is conducting by a concentration gradient.
Osmosis is a process in which solvent (molecules) pass through a semipermeable membrane (SPM) from a lower concentration solution region to a higher concentration region so it equalizes the concentrations on each side of the SPM.
A <u>hypotonic solution</u> is a solution that has a higher concentration of solutes inside the cell than outside of the cell. Thus the movement of water is from outside to the inside of the cell.
A <u>hypertonic solution</u> is a solution in which solutes concentration is greater outside the cell and low concentration inside. The movement of water is from inside the cell to outside the cell.
An <u>isotonic solution</u> where two solutions having the same concentration inside and outside of the cell so there is free movement of molecules across a semipermeable membrane.
Like three sometimes four it depends..
Answer:
Explanation:
The BUN test or blood urea nitrogen test measures the concentration of urea and nitrogen present in the blood. This describes how well the two kidneys in the body are functioning. Urea and nitrogen are the two waste products produced by the liver that travels through the blood to the kidneys. The test is done by drawing blood out of your body through a vein of the arm. The small amount of urea and nitrogen in the blood can be considered as normal the excess urea and nitrogen in the blood indicate s that it is not filtered by the kidneys.
