Summarize what the researchers did to improve the quality of post mining site soil
Salsk061 [2.6K]

Answer:

The researcher centred on the potential uses of biochar, charcoal primarily used for agricultural and to improve the quality of post mining sites.

A method called mountaintop removal was used by mining firms. This means that they remove rock and mineral deposits off the top of the mountain to gain access to within the coal seams. The resulting soil is infertile and strongly acidic. The compacted soil after mine proves harder to  bring seed into the soil.

The researchers  try to use biochar to help reforest the soil at the post-mining site. Before it was reseeded and replanted, they got permission to add a layer of biochar to a post-mining site. the team created “planting cells” of biochar‐enhanced soil on the post‐mining site and that showed improvment in the sapling growth.

In ____, several sets of alleles control the phenotype and each dominant allele present codes for a product which has a quantita
tatuchka [14]

Answer:

Polygenic inheritance

Explanation:

Polygenic inheritance occurs when a genetic trait is regulated by more than one genes. All the alleles of these genes together determine the phenotype of the organism for the polygenic trait. Here, the phenotype is regulated by the total number of dominant alleles for all the genes that regulate a polygene trait.

For example, human skin color is a polygenic trait. The final phenotype depends on the total number of dominant alleles of all the genes that regulate the skin color in human.
