Scientists have tried lots of different ways of predicting earthquakes, but none have been successful. They haven't been able to find a signal for earthquakes( there is no obvious sign to say that an earthquake is coming very soon). They do have a pretty good idea of where an earthquake is most likely to hit, but they still can't predict exactly when it will happen.

However, the probability of a future earthquake can be calculated, based on scientific data. Scientists estimate that the probability of a major earthquake occurring in the San Francisco Bay area over the next 30 years is 67%.

WILL MARK BRAINLIEST FOR BEST AND ACCURATE ANSWER! What are the three parts of a nucleotide?

nasty-shy [4]

The nitrogenous base is the central information carrying part of the nucleotide structure. These molecules, which have different exposed functional groups, have differing abilities to interact with each other.

The second portion of the nucleotide is the sugar. Regardless of the nucleotide, the sugar is always the same. The difference is between DNA and RNA. In DNA, the 5-carbon sugar is deoxyribose, while in RNA, the 5-carbon sugar is ribose. This gives genetic molecules their names; the full name of DNA is deoxyribonucleic acid, and RNA is ribonucleic acid.

The last part of nucleotide structure, the phosphate group, is probably familiar from another important molecule ATP. Adenosine triphosphate, or ATP, is the energy molecule that most life on Earth relies upon to store and transfer energy between reactions. ATP contains three phosphate groups, which can store a lot of energy in their bonds. Unlike ATP, the bonds formed within a nucleotide are known as phosphodiester bonds, because they happen between the phosphate group and the sugar molecule.
