How is energy from nuclear fusion transferred through the layers of the sun?

By radiation and convection.  

Step-by-step explanation:

Just outside the core is the radiative region.

Here, ions of hydrogen and helium emit photons that travel a short distance before being reabsorbed by other ions, and the process repeats many times.

After several hundred years, a photon reaches the convective zone, about 200 000 km below the surface.

The temperature near the radiative zone is about 2 000 000 K but only about 5700 K at the surface.

Pockets of hot plasma rise to the surface in convection currents, much like water boiling on a stove. This journey takes about 10 days.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
