Im not sure how to answer this since there were no choices given but I will answer by telling you what nuclear fusion is...
so basically nuclear fusion is the merging or combining of 2 isotopes, typically isotopes of hydrogen, under conditions of extreme temperature and pressure thus resulting in the release of massive amounts of energy. I think the answer to your question would be new types of electricity because the heat emitted from the reaction could be turned into electricity by using its steam. This is what happens in nuclear reactors  
i hop this answers your question

Answer:
Malaria can be described as a disease which is caused by a parasitic organism. The Anopheles mosquito carries the parasite Plasmodium in it. When this mosquito bites a human being, the parasite gets transferred into the blood of the person causing malaria. Before entering the blood cells, the plasmodium travel to the liver where they get matured. 
Malaria is a life-threatening disease which kills many humans each year, especially people living in underdeveloped countries.
 
        
             
        
        
        
Answer:
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.
