Many reasons are involved in this combination. First, as bone cancer is not easy to determine, doctors may have to use biopsy to have a first look, but it needs to be paired with x rays and different scnas to confirm and do it more acurately. Some bone infection may cause symptoms and imaging results that could be confused with bone cancer.Have in mind that <span>bone metastases can usually be diagnosed based on x-rays and other imaging tests.A combination of all the scans and X rays can help to detect bone cancer in different places of the body, as every method can show tumors in specific parts of the skeleton. </span>
Protection of certain species is a very controversial topic. Many species like the mountain lion or jaguar that are near extinction in certain areas, are threats to human life. Another reason is that they could off set the food chain when they come back and be stonger than ever. For example the mountian lion could eat out the thriving white tail deer population which was struggling because of the mountain lion. And many people rely on white tail deer for food.
Hope this helped :)
The bond formed between the sugar of one nucleotide and the phosphate of an adjacent nucleotide is a covalent bond. A covalent bond is the sharing of electrons between atoms. A covalent bond is stronger than a hydrogen bond (hydrogen bonds hold pairs of nucleotides together on opposite strands in DNA).
Scientists have tried lots of different ways of predicting earthquakes, but none have been successful. They<span> haven't been able to find a signal for earthquakes( there is no obvious sign to say that an earthquake is coming very soon).</span> 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%.
