<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.

Water exhibits capillary action.
When the water and nutrients travel from the roots of the plants to the various parts of it, transport is needed to make this phenomenon occur.
The active transport is the process by which a substance is transported or transferred from one area to another using a chemical energy in the course. <span>As oppose to passive transport, active transport’s key to its description uses energy to be able to transfer the said substance. This is important in a lot of aspects such as providing the needed elements or compounds in cellular activity.<span> </span></span>
Even though this belief eventually gave way to Darwin's theory of natural selection acting on random variation, Lamarck is credited with helping put evolution on the map and with acknowledging that the environment plays a role in shaping the species that live in it.
