<span>it was molecular structure of DNA this was appeared 1n April 1953 Watson and Crick presented the structure of DNA- Helix.it carried the genetic information. the DNA Molecule shaped in twisted ladder.franklin produced an X- ray photograph.
DNA structure is made of molecules called nucleotide. Watson and crick also work on 3-D structure of DNA. this mark the history in molecular biology to understanding the genes control and genetic information.they also work on cell.they use stick and ball to understand to test their idea.</span>

Answer:
In the Precipitation Map of Washington, the dark orange section indicates low rainfall in the region. Using the Shaded Relief Map of Washington, you can tell that this area is flat, possibly a plain. These regions typically don't receive a lot of rain. The Precipitation Map of Washington has areas that are dark purple and dark green. This indicates that they both receive a lot of rainfall every year. If you look at these areas on the Shaded Relief Map of Washington, you can tell that these areas with a lot of rainfall are mountainous.
On the Precipitation Map of Washington, purple/blue means more rain, and orange/red means less rain. The Shaded Relief Map of Washington shows mountains (brown), valleys, plateaus, and canyons. Areas that are flat are smooth on the map. Areas with steep slopes and mountains look rougher.
Explanation:
Answer: the dam cause no more fertile soil to enter in to farmers land for growing crops hope this helps :)
Explanation: this dam has caused a big change to the lifes of farmers downstream from the dam. Usually when the river flooded once a year before the dam was built. It deposited fertile soil from upstream on its banks downstream. This washed up soil was extremely furtile, and renewed itself every year at in flood season. But now, since the dam was built the annual flood has been stopped. Causing all the farmers downstream to have to use fertilizers to grow their crops, which makes it more expensive.
