What happens in nuclear fusion reaction is that<span> four hydrogen </span>nuclei combine in a <span>proton-proton </span><span>fusion </span><span>to form one </span>helium atom. In the process of fusing to form the helium atom, some of the mass of the hydrogen atoms is converted into vast amounts of energy, which is released.
Answer:
The breathing rate increases.
These organisms convert nitrogen in the soil to ammonia, which can then be taken up by plants. This process also occurs in aquatic ecosystems, where cyanobacteria participate. After nitrogen has been fixed, other bacteria convert it into nitrate, in a process known as nitrification.
