If it changes more rapidly, few adaptive walks will be completed, and the population will be poorly adapted most of the time. If it changes very rapidly selection may be inadequate to restore adaptation quickly enough, and the population will dwindle and eventually become extinct
Not being able to adapt creates competition from those who can adapt. This is called the survival of the fittest. New predators and loss of habitats create environmental pressures that can limit the growth of a population and lead them to extinction if they are unable to adapt. The faster the change occurs, and the more drastic the change is with respect to the way that species lives, the more likely it is that the species will not be able to adapt in time and may disappear. This is also called Natural selection.
A single layer of phospholipids forms what is called a micelle. The polar and hydrophilic phospho head groups would form the outermembrane which interacts with the aqueous environment. The nonpolar and hydrophobic lipid tails would be in the cytosol where they pack tightly and form stable interactions with the hydrophobic chains of the stored oil molecules.
Other deposits may be from fossilized bone or bird droppings called guano. Weathering and erosion of rocks gradually releases phosphorus as phosphate ions which are soluble in water. Much of the phosphate eventually is washed into the water from erosion and leaching.
