Some of the properties that will change as the biological membrane composed primarily of phospholipids change from the saturated to unsaturated fatty acid tails of the phospholipid would include, permeability of the membrane, this will cause the membrane to be more fluid and not remain as controlling of the materials. The membrane will ultimately become poor in regulating ions and other materials from coming into the cell, as the phospholipids are not tightly packed due to them being unsaturated and having carbon double bonds within them. This can also affect the overall shape of the plasma membrane as well, causing it to be not as structured, and more fluid,
Answer:
sodium is metal because it has one electron in its outer shell and gives it to other to be stable.so it is metal.but sulfur gains 1 electron from other so it is non metal.
The reaction between iron and nitric acid eventually produces a red-brown rust colour (iron(III) oxide). could link this with corrosion and acid rain
