Intermediate filaments are uniquely non-polar and built by lateral bundling in five steps: 1. synthesis of an alpha-helical monomer
2. formation of a coiled-coil dimer
3. formation of a staggered tetramer of two coiled-coil dimers
4. lateral association of 8 tetramers
5. addition of 8 tetramers to a growing filament.

At what step is polarity lost?

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
