Enzymes at the wrong pH experience changes in the charge of the molecule, this can cause impacts on hydrogen and iconic bonds. Enzymes become denatured as terry structure is lost and the active site is no...

Increase in surface area, which is provided by the many alveoli that are located at the end of the bronchioles. These can number in the thousands.
The alveoli have a thin wall, one cell thick, so dif...

-       Larger cell have smaller SA:Vol Ratio-       Difficulty in exchange materials-       Multicellular more efficient-       Revisit – transfusion, osmosis, active transport

The loop of henle is a region of the kidney's nephrons which through active and passive transport of Na+ and Cl- ions lowers the water potential of the kidney's medulla, allowing greater reabsorbtion of w...

Osmosis is the net movement of water from an area of high water potential to an area of lower water potential through a partially permeable membrane.An area of high water potential means there is less sol...
