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.

2.) Laws of Genetics

Explanation:

George Mendel has discovered the fundamental laws of Genetics or inheritance by working on his pea plant, Mendel founds that Genes come in pairs and they are inherited as specific units each one is different from parents.

Inheritance Genetics is when something is passed down from one generation to the next generation.

Write one scientific question about the organism in the photo? With sunflowers
vodomira [7]
How did the sunflowers depict their rivalry in the image? Why should they fight it out?
The reason I've chosen this as a scientific topic is because the area is covered in sunflowers. With the conditions of their surroundings, living organisms attempt to live. As a result, there is rivalry among the organisms.

The PCR primer ‘D7S820’ is used to amplify the D7S820 locus. Using this gel below, determine whether each person (M1, P1, P2, C1
Ahat [919]

Answer:

1) M1 is heterozygous since it contains 2 bands, which means that it contains one recessive and one dominant allele

P1 is homozygous for this locus, since it contains a single band or is known to be homozygous for the locus or gene.

P2 is hetozygous for this locus because two bands appear in which each band represents one allele for the gene.

ChildC contains two gel bands, representing two alleles and is therefore heterozygous

P1 is the father of the child C1, if we look at the gel, each father shows a similar band, one coinciding with the mother and the second with the father p1

As for the paternity study, the PCR test is not useful, since it provides asymmetric results, thus only one strand information will be provided, and because the DNA is double-stranded, a more complete study is required.:
