<u>X-Ray crystallography</u> was the technique that helped Watson and crick in developing their model for the structure of DNA.
A crystal's crystalline structure causes a beam of incident X-rays to diffract into a variety of distinct directions, which is how X-ray crystallography, an experimental science, determines a crystal's atomic and molecular structure.
Famous researchers Watson and Crick made history by figuring out the structure of DNA. They discovered that DNA is composed of two strands wound around one another to form a double-helical structure using X-ray crystallography. It was developed by Rosalind Franklin using an approach called X-ray crystallography and showed the DNA molecule's helical structure. The genetic code for all living things is encoded in two chains of nucleotide pairs that make up DNA, as Watson and Crick discovered.

Answer:
Support the plant.
Explanation:
Long answer:
Holds the plant in the ground/ soil.
Provides nutrients and water from the dirt, to the stem.
A) physical properties because it is not changing its chemical properties and there is no such thing as internal properties.
The reason the flower is pink, is mainly because when you mix a light color ( in this case a a white flower) in with a red, it creates a pink color. In others words, when you mix white and red, it creates pink. Hope this helped!
The functional groups determine the shapes of macromolecules and this in turn determines their functions. ... Proteins have complex structures caused by interactions between the functional groups. A change of a single amino acid can make a major change in the function of a protein.
