Answer:
The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
Explanation:
Your answers are 2. It contains 46 chromosomes and 3. Each strand contains chromosomes from one parent.
<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.
