Answer: The sun is what makes the water cycle work. The sun provides what almost everything on Earth needs to go—energy, or heat. Heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form clouds... clouds that move over the globe and drop rain and snow
The reason is that DNA sequences code for certain amino acids. If you look at an amino acid chart there are more than one way to code for certain amino acids. For an example say GGTTA codes for a certain amino acid. But it got changed to GCTTA even though it changed this particular mutation was just another way to code for the same amino acid. So it wouldn't affect the phenotypic expression. It basically is a different way to code for the same things.
False.
The layering is usually thin.
Deoxyribose is found in DNA, whereas ribose is found in RNA. Deoxyribose is also a double helix while ribose is a single helix
