Explanation:

Mitochondrial DNA typing -

This method is mainly used by forensic scientist who investigate crime scenes.

It involves the use of DNA from an unknown sample to match a DNA collected from a crime scene.

This method is normally used in special scenarios.

These scenarios include:

1) When the DNA is discarded.

2) When the sample does not contain nuclear DNA.

From the description above we can now answer the question as follows:

an unknown nuclear mtDNA is matched to a nuclear mtDNA found at a crime scene.

What evidence supports Hess's theory of seafloor spreading? Check all that apply.

Zarrin [17]

The direction iron in ocean rocks points

The new crust, formed at constructive/divergent boundary (regarding tectonic plate movement), has band-like patterns that orient in different directions (in alignment with earth's magnetic fields) and visible on the surface. This shows that it is newly made crust made from new magma.

Explanation:

These bands are firmed when the iron minerals in magma orient themselves with the earth's magnetic field before the magma cols into rock and lock the minerals permanently in position. This magma upwells from the mantle to fill the void made when the tectonic plates are moving away from each other.

The earth's magnetic field on the other hand is dynamic. Its angle increases gradually from the true north or south and then flips orientation over several hundred years. The iron minerals therefore will align differently depending on the orientation of the earths magnetic field at the time. This is why the new crust has band-like features visible on its surface.

One method of lessening the environmental impact of strip mining is by replacing landscaping after mining. This will help to seal off the bare land to avoid accidents. It also prevents soil erosion of the lose soil due to mining. Landscaping will modify the features of the land and make it beautiful and environment friendly
