Answer:
1. The lines (or bands) represent pieces of DNA of different sizes. If two samples come from the same individual, all bands in one sample must match up with all the bands in the other. Compare the bands in each sample and determine if either suspect left the blood found at the crime scene.
2. Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth's tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.
3. Magmatic and tectonic processes at mid-ocean ridges form oceanic crust and accommodate relative plate motions. Oceanic lithosphere forms and becomes denser as the plate moves away from the mid-ocean ridge and cools.
4. I think it's the same with number 2?
I really hope it helps:)
