Thnx

Answer 1

1. False (charged ions like Na+, K+ being polar require special protein channels for their transport across the cell membrane)

2. True

3. False. It is number of moles per one liter and one mole contains Avagadro's # of molecules or particles.

4. ??? Edema is free fluid in interstitial space so, may be True (not sure of this one)

5. True. (Only two organs with negative interstitial hydrostatic pressure are skin & lungs)
