The invasive species are the species who are present in a non native ecosystem. The invasion of These species disturbs the environment of particular system by increasing the competition or destroying the vital component of the ecosystem.
The invasive species like brown tree snake exhaust the food of the other animals present in the ecosystem, as they are capable eating almost every type of food. Due to the presence of the brown tree snake, the competition for food increasing, which result in disappearance of many native species. Other invasive species can feed on the native species and cause decrease in their number, so, the invasive species disturb the ecological balance in the ecosystem.
Answer:
It allowed us to put a formation date on some geologic crossections
Explanation:
Absolute dating is a newer way of evaluating the chronology of historical events by assigning numerical ages to them. The age thus assigned might not be the exact age but it is still closer to the real age.
It is unlike relative dating techniques which simply give the chronology or order of past events instead of the exact dates. Relative dating techniques have been in use before the emergence of absolute dating techniques in the twentieth century.
To classify animals and distinguish them

Therefore, a 10x eyepiece used with a 40X objective lens, will produce a magnification of 400X. The naked eye can now view the specimen at a magnification 400 times greater and so microscopic details are revealed. More on objective lenses here. Magnification is the ability to view an object as larger.
Without a charge, it would be 35 electrons. Protons have a positive charge and electrons negative. They must balance each other out, otherwise the atom will be charged.
