Atoms heavier than helium were at one time manufactured by
A)photosynthesis.
B)thermonuclear fusion.
C)radiant energy conversion.
D)radioactivity.
E)none of the above

Question

Quizplus · Accepted Answer

Atoms heavier than helium are synthesized through thermonuclear fusion, which occurs in stars. The fusion process occurs at extremely high temperatures and pressures, causing lighter elements to fuse and create heavier ones. This process is also what powers stars, including our own Sun. Photosynthesis is the process by which plants convert sunlight into energy, and radiant energy conversion refers to the conversion of one form of energy into another using electromagnetic radiation. Radioactivity involves the decay of atomic nuclei, and while it can produce new elements, it is not the primary process by which atoms heavier than helium are synthesized.
