How did hershey and chase build upon avery's chemical analysis results?

Avery chemical analysis result showed that the element phosphorus is present in the transforming principle. Hershey and Chase build upon Avery's chemical analysis results and used it to show that the transforming principle is DNA and not protein and that the element phosphorus is present in the DNA molecule and not in protein. They did this by infecting bacteria with phages. The phages used had their DNA tagged with radioactive phosphorus. Their results showed that radioactivity was present in the bacteria used. 

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
