Answer:
Difference between fusion reaction and fission reaction.
Explanation:
Fission reaction produce energy while fusion reaction absorb energy.This happens because fission reaction deals with the breakdown of one larger nucleus which result in the generation or liberation of energy.Whereas Fusion reaction combines two smaller atomic nuclei,as a result of which it requires energy for the joining of two smaller atomic nuclei into a larger nucleus.
<span> Very inefficient. Almost 90% of all energy is lost between trophic levels. That is why larger animals need to eat more, because less energy is being consumed.

Myosin and actin protein filaments attach to each other . Calcium ions release into myofibrilles . Myosin filaments pull on the actin filaments
