Why are the fields of science and mathematics so interdependent? select all that apply. scientists need to be able to illustrate scientific laws and formulas. scientists need to be able to take careful measurements. scientists cannot rely so heavily on calculators and computers. scientists need to be able to make precise measurements.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
