When meselson and stahl performed their experiments on dna replication, they grew cultures of e. coli in a heavy isotope of nitrogen (15n), then transferred cultures to a light isotope of nitrogen (14n) and allowed the cultures to grow in the latter for one or two generations. if replication occurred through a conservative mechanism, which of the following results would they have obtained?

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
