Answer:
Using Bacteria such as Acidithiobacillus ferrooxidans to leach copper from mine tailings has improved recovery rates and reduced operating costs. Microbial leaching is especially useful for copper ores because copper sulfate, as formed during the oxidation of copper sulfide ores, is very water-soluble.

Answer:
Three ways a scientist can reduce bias include: 1) Sampling a larger pool (assuming the subjects are human) in order to broaden recorded data. 2) Making sure to sample more than one group. This means to not just sample one's friends, etc.
Improper agricultural methods may elevate concentrations of nutrients, fecal coliforms, and sediment loads. increased nutrient loading from animal waste can lead to eutrophication of water bodies which may eventually damage aquatic systems.
The answer is C or B.
If it was permeable water and other substances could get through.
And hard? That is one of those answer choices teachers throw in to try and make an obvious elimination choice.
I hope I have helped!
The right answer is BB or BO
The blood group is inherited through a gene located on chromosome 9. Call it the ABO gene. The ABO gene exists in 3 forms, called alleles. We inherit one of these alleles from each of our parents.
The combination of these two alleles is called genotype. The blood group that results from this combination is the phenotype.
* B and B give the BB genotype, which means at the phenotype level, blood group B.
* B and 0 give the B0 genotype, which means at the phenotype level, blood group B, because B is dominant.
