Answer:
By 1900, Fingerprint was the evidence which was collected at crime scenes to help positively identify suspects by one particularly unique trait. No two people can have the same type of fingerprints. It is a unique characteristic which is even not common among identical twins. Therefore, was considered as an important evidence for identification of suspects and linking them with the scene of offence. In 1904, the city of St.Louis, Missouri used fingerprint evidence for the first time for criminal identification.
The statement is - True.
The production of the nuclear energy by the nuclear reactors requires lot of water. The water's role is to constantly keep cool the reactors because if they overheat there can be a disaster of big proportions.
Because of the heating up of the water the water changes its properties slightly. Those changes have big environmental impact, easily seen in the local flora and fauna in close proximity to the nuclear reactors. There is way to big of a percentage of bad mutations among the flora and fauna where the water is released from the nuclear reactors, where very often there's animals with either more or less extremities, two heads, weird growth and shape of the plants etc.

It causes eutrophication which means that the algae have too much nutrients and take over the pond, use the oxygen so there is not enough left for marine life, which die as a result.
When using the term 'life form' I assume you are speaking of animals, bacteria, etc. Scientists take years to find their desired conclusion because of how the environment tends to change quite frequently (Depending on where the creature lives). The earth is constantly revolving and rotating, which causes changes in the environment. These changes affect the animals behavior, eating habits, and overall chances of survival. A factor that must also be considered is that scientists have to examine these creatures in their natural habitat which can be an issue depending on where they live. For example, if I were to study the behavioral patterns of a Leopard, it would be extremely difficult to do so because the Leopards are specifically keen at camouflaging in their environment. That would make observing its behavioral patterns very frustrating and time consuming. In a way, mother nature is always against us.
(Hope this helps)
