Which conditions are required for nuclear fusion to begin? The gas cloud must be very dense. Gravitational attraction must stop. Atoms must be stripped of their electrons. Helium atoms must break down into hydrogen. Temperatures must exceed 14 million Kelvin.

Explanation:

Fusion requires temperatures about 100 million Kelvin (approximately six times hotter than the sun's core).

At these temperatures, hydrogen is a plasma, not a gas. ...

The sun achieves these temperatures by its large mass and the force of gravity compressing this mass in the core.

this process is called "phosphorylation." a phosphate bond joins adenosine diphosphate to form adenosine triphosphate.

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
