1. Bacteria where grow in a medium composed of heavy nitrogen. After several generations the bacteria DNA was composed of heavy nitrogen (heavy nitrogen is an isotope of nitrogen).
2. After several generations had passed, the bacteria were transferred to a nitrogen light medium.
3. As soon as the bacteria were transferred the bacteria DNA was isolated after the first and second generation through centrifugation.
4. Results: after 2 generations half of the DNA was intermediate and half was light; there was not heavy-only DNA. The conclusion was that the new DNA is formed by an "old" strand and a "new" strand producing an intermediate weight.

Explanation: If you were to travel to the desert, the only plants you would find would be shrubs and cacti, because unlike most plants, they are able to survive in a dry climate with very little water. All plants need the basics- that is, sun, water, and CO2, but only a select few have been able to adapt to the harsh desert climate. There are other places in the world where there is intense sunlight all day, (like my front yard, for example, which is ALWAYS yellow smh) but the plants usually are okay as long as they get enough water, which my grass doesn't lol.
