charged molecules such as ions can</span> pass <span>through cell</span> membranes
by facilitated diffusion using specific transmembrane protein channels, which act as
transporters that are implanted into the plasma membrane. Such transport proteins regulate the selective
permeability of cell membranes and play a critical function in cell membrane.
<span>Moreover,
this specific transmembrane protein have multiple membrane-spanning regions
that create a passage through the phospholipid bilayer, allowing charged
molecules to pass the membrane through a protein pore without interacting with
the fatty acid chains of the membrane. </span>
Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. ... At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed.
