1) A few things that sound waves can go through pushing the particles of the medium, closer together, the particles that have been upset at that point push adjoining particles, prior to bobbing once again into their unique positions. An example can be a guitar string producing sounds.
2) Light waves can travel however space through a vacuum a totally airless space.
1. because everything you can see has particles that can vibrate but if there are no particles, nothing to bump into to create that vibrate in this case sounds can't travel.
2. light waves can travel through a vacuum does not require a medium. In empty "space," the wave does not grow smaller no matter how far it "travels" because the wave is not interacting with anything else... As a "wave travels" from a source, it spreads outward in all directions.
This is what I got I don't know if this is the answer that you were hoping for but I hope that it'll help you!
These base pair relationships are often called Chargaff's rules of DNA base pairing, named after the Columbia University scientists who observed that there are equal molar concentration of A & T, as well as G & C in most DNA molecules.
