(1) Bacteria divide symmetrically during normal growth and have a central constriction to bring about binary fission of the cell.

(2) The fission process itself provides a mechanism for creating a so-called u251cu00f6u251cu00e7u251cu2510chain reaction.u251cu00f6u251cu00e7u251cu00fb

(3) Several of these new departments have been reorganised on a number of occasions to accommodate shifting trends in policy, through what might be referred to as a process of fission and fusion.

(4) Because fission releases additional neutrons, a chain reaction can take place.

(5) These heavy nuclei can also fission

(6) In most cases, the purpose of a nuclear reactor is to capture the energy released from fission reactions and put it to some useful service.

(7) Apparently, this creature reproduces by binary fission , a process common to the single cell creatures of earth.

(8) Because tribes are so segmental and undifferentiated, their constituent parts - e.g., families, lineages, clans - tend to oscillate between fusion and fission .

(9) Bacteria divide by transverse binary fission

(10) These fission products are not found in natural background radiation, but are exclusively byproducts of nuclear weapons explosions and nuclear reactor operations.

(11) It produces no fission radioactive by-products or fallout of serious concern.

(12) The party dissolved into fission and acrimony

(13) During fission , a nucleus splits into two nuclei of less mass with greater stability.

(14) In the current wave, processes of fission and disintegration predominate.

(15) The ecclesiastical fission has led to some tiny island villages being split religiously among as many as five different bodies.

(16) Primarily they reproduce asexually, which they accomplish by binary fission , or simple cell division.

(17) In either case, she is no longer with him, another fission in this song of mournful departures.

(18) There are many great ideas for both fission and fusion.

(19) A fission product

(20) As already noted in the context of the collapse of communism, this challenge to the map has taken the form both of fission and fusion.
