In many simple organisms, including bacteria and various protists, the life cycle is completed within a single generation: an organism begins with the
fission
of an existing individual; the new organism grows to maturity; and it then splits into two new individuals, thus completing the cycle.
选项
A、split
B、fusion
C、explosion
D、modification
答案
A
解析
A项split“劈开,(使)裂开,分裂,分离”与画线词fission“裂开,分裂,分体”的意思相吻合,如Argument over policy led to a split in the party(有关政策的争论导致了党内的分裂),故选A。B项fusion“熔化,熔解,熔合,熔接”;C项explosion“爆发,发出,爆炸”;D项modification“更改,修改,修正”,均与画线词的意思不一致。
