Give one
example of how bacteria maintain
equilibrium in the environment.

-Some produce organic compounds and some break down organic compounds.

-Bacteria are vital to maintaining the living world. Some are producers, others are decomposers, and others have human uses.

-Bacteria act as decomposers. They recycle the nutrients, such as breaking down a dead tree into simpler materials, thus helping out the ecosystem

the last 2 are the same i think but i hope this helps :D

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
