Answer: Structural chromosomal mutation
Explanation: In translocation, a small piece of chromosome is detached from one chromosome and is attached to another non-homologous chromosome. Translocation can be simple, shift or reciprocal.
Simple translocation involves single break in the chromosome. The broken piece gets attached to the end of the non-homologous chromosome.
In Shift translocation, the broken segment of one chromosome gets inserted interstitially in a non-homologous chromosome.
Segment from one chromosome is exchanged with a segment from another non-homologous chromosome simultaneously in Reciprocal translocation.
These circular DNA molecules are called C: Plasmids
Microorganisms such as bacteria can be removed by disinfection. Certauns substances called biocides are addes to water to make it pure. Purification can also be done by UV-light .
Natural ladybugs.
You can indeed use ladybugs in a pest control, but that depends on the pest. Since in the question, you don't specify what the pest is, the answer is natural ladybugs.
If the animal was something that ladybugs eat, like aphids for example, than ladybugs could be used as a pest control insect.
