Answer:
Open-cast mining
Explanation:
The aftermath of open cast mining are pits (called quarries) on the surface of the earth where the surface soil has been removed/ displaced to access the mineral deposits that are just close or at the surface of the earth. This type of mining results in environmental degradation because they disturb the biodiversity of the ecosystem in which the mining is taking place. Rehabilitation of the area is required after the mining has been exhausted to restore the initial environment.
Answer:
hmm
Explanation:
what, tell me the answer your looking for is it definition or where they are found
Each (both large and small) colony is carefully counted (using magnifying colony counter if needed). Each colony represents a “colony-forming unit” (CFU). For accurate counts, the optimum count should be within the range of 30-300 colonies/plate. To insure a countable plate a series of dilutions should be plated.
Answer:
Genetic drift.
Explanation:
Genetic variation is the change in the genome of the organisms. The genetic variation might occur in the population due to the natural selection, mutation and genetic drift.
As the information given in the population, the variation is possible due to the genetic drift. This mainly occur due to the random sample of the small population and might cause the complete loss of the particular gene. The genetic variation might decreases in the organisms.
Thus, the answer is genetic drift.
