Well, first off, the sediments get brought down from the mountains after eroding away. Those sediments combine with others as it passes through the creeks and streams, rivers etc. Whatever dies, for example lets say chum salmon since they have nutrients within them. They aren't good swimmers so they are normally at the mouth of the river or in the small streams nearby. When they die, their nutrients go into the soil, that soil or whatever nutrients in that, could be swept out to the wetlands and piled up. Thus, adding rich nutrients. Adding the sediments from high up, you have a rich supply of nutrients from the wildlife that dies there as well.
Answer:
Polar; hydrophobic (Ans. B)
Explanation:
Glycerophospholipids are known as the class of lipids which are found extensively in the biological membrane. They are usually consisting two regions of lipids which provide structure to the lipid bilayer in which the hydrophilic heads (polar) attaching outside to the cell and the hydrophobic tails (non-polar) pointing insides to the cell membrane.
Glycerophospholipids helps to provide permeability and fluidity to the membrane and also helps in the programmed cell death, and modulation of actions of membrane-bound enzymes.
