The right ventricle is deoxygenated. It is responsible for the pumping of the deoxygenated from the heart to the lungs.
Primary succession is a method of fertilizing soil that was barren and had never supported plant life, for example soil left over by a moved glacier of lava.
The soil is first "normalized", using pioneer species such as lichens, algae and fungi.
After this, plants able to survive in less harsh conditions such as grasses.
Therefore, the fertility of soil during early years of primary succession does not increase much and it is a process that involves a long period of time.
It results from the composition of the cell membrane. The cell membrane consists of a phospholipid bilayer, which have hydrophilic heads and hydrophobic tails. Hope this helps! :)
