Which three statements accurately describe the blood buffering system in humans? the blood buffering system depends on the ionization of h2po–4 . the blood buffering system is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid, ionizing into bicarbonate and h+ . the blood buffering system utilizes the h2co3 / hco–3 conjugate acid/base pair. the blood buffering system utilizes the acetic acid/acetate conjugate acid/base pair. the blood buffering system maintains the ph of blood near 7.4.

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.
