True, laboratory examination may narrow the origin of such evidence to a group of persons that includes the suspect.
More about laboratory examination:
Scientists examine the evidence gathered from crime sites, suspects, and sufferers in crime laboratory. They can examine everything, including DNA, biometrics, human body parts, and questionable objects.
Numerous labs have seen increased responsibilities as a consequence of the increasing reliance on scientific approaches in criminal investigations. By narrowing their procedures and offering up-to-date training, NIJ is committed to assisting crime laboratories in growing their capacity to keep up with technological advancements in crime solving.

not sure if this helps but I hope it does
sorry its so long
To date erosion scientists have failed to address — or have addressed inadequately — some of the ‘big questions’ of our discipline. For example, where is erosion occurring? Why is it happening, and who is to blame? How serious is it? Who does it affect? What should be the response? Can we prevent it? What are the costs of erosion? Our inability or reluctance to answer such questions damages our credibility and is based on weaknesses in commonly-used approaches and the spatial and temporal scales at which much research is carried out. We have difficulty in the recognition, description and quantification of erosion, and limited information on the magnitude and frequency of events that cause erosion. In particular there has been a neglect of extreme events which are known to contribute substantially to total erosion. The inadequacy and frequent misuse of existing data leaves us open to the charge of exaggeration of the erosion problem (a la Lomborg).
Models need to be developed for many purposes and at many scales. Existing models have proved to be of limited value, in the real as opposed to the academic world, both because of problems with the reliability of their results, and difficulties (with associated costs) of acquiring suitable data. However, there are some positive signs: models are now being developed for purposes including addressing questions of off-site impacts and land-use policy. Cheap, reliable and technically simple methods of erosion assessment at the field scale are needed. At the global scale, an up-date of GLASOD based on a scientific approach is urgent so that we are at least able to identify erosion ‘hotspots’.
In terms of explanation of erosion, the greatest need is for a full recognition of the importance of socio-economic drivers. The accession of new countries to the EU with different economic and land-use histories emphasises this need. Too often we have left people, especially the farmers, out of the picture. Our approach could be characterised as ‘data-rich and people-poor’.
Answer:
The main goal was the total elimination of poverty and racial injustice
Answer:
Classical conditioning
Explanation:
In psychology, classical conditioning is a method of learning by pairing stimuli. Usually, first one stimulus causes a natural answer (the unconditioned stimulus causes an unconditioned answer), then this unconditioned stimulus is paired with another stimulus that doesn't cause an answer by itself at first but after some repetitions, the new stimulus (conditioned stimulus) causes the same answer from the unconditioned stimulus and this answer becomes the conditioned answer.
In this example, pets have learned to pair the sound of the electric can opener with the arrival of their canned food so they have learned to respond to this sound and therefore, they run toward the sound of the can opener even if there is no cat food present. <u>The can opener would be the conditioned stimulus which has been paired with the food (unconditioned stimulus) and has created the response of the pets running toward this sound (Conditioned answer). </u>Therefore this is an example of classical conditioning.
Spartans were trained from the time they were seven years old to be warriors. Girls as well as boys were taught in the art of war. The Spartans also lived a very austere lifestyle so that they would be used to long millitary campaigns.
