The answer is; hydrophilic heads; hydrophobic tails
The hydrophilic heads of a phospholipid are composed of a phosphate and glycerol molecule. Since the phosphate has a charge, the head are able to interact with water molecules through hydrogen bonds (Remember water is a polar molecule). The hydrophobic tails are composed of hydrocarbon chains that are uncharged hence do not interact with water. When phospholipids are immersed in water, they form a bilipid layer - with the hydrophobic tails clumped up together in the center and the hydrophilic heads on the outside.
<span>Volcanoes form at different plate boundaries because of the plates divergent and convergent nature. the plates are always in motion, however minimal they may be. When the plates move apart from each other, the magma from below comes up to fill in the vacant space and thus a volcano is formed. It may be the other way round also and that is the magma forces the plates to move away and this results in the formation of a volcano. When one of plates dives under another plate, then the pressure creates melting of the mantle and thereby forms magma which in turn creates volcanoes.</span>
