Afew key experiments to discover the structure of the dna molecule. who was responsible for the research suggesting that dna had a helical structure with a relatively uniform diameter and was probably too wide to be a single-stranded helix?

Dr. James Watson and Francis Crick

Explanation:

It was Dr. Rosalinda Franklin who first take a picture of DNA in its helical structure. Using this picture of Dr Franklin, Dr. James Watson and Francis Crick recognized from the image and suggested that the DNA has a double helix structure. They assemble a model of the DNA structure and wrote a paper describing the DNA as a double helix.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.
