The main molecules present in the plasma membrane are<em><u> phospholipids</u></em>, those molecules are made of a polar, hydrophil end(glycerol with a phosphate group attached) and two non-polar, hydrophobe ends(two fatty acids rests). The cell identity is determined by <u><em>proteins </em></u>present in the membrane, a very important type of protein that determines the identity of a specific cell is called marker. The membrane fluidity is reduced by a lipid with a ring structure, <u><em>cholesterol</em></u>, this molecule belongs to a class of biomolecules called steroids.

Canada is the country that has the most forest area from the countries on this list. It is actually the second country in the world by forest area, with only Russia being in front of it. Canada has around 4,916,438 km² of forest. Brazil is very close to it, and it is in the third place globally, with the United States being placed as fourth, China as fifth, and Argentina as eight.
Canada's forests are stretching pretty much all over its southern half, creating a landscape of dense coniferous forests, and in certain areas of deciduous forests. Even Canada's flag has a leaf on it, more specifically a leaf of a maple tree.
