Some people worry that the increasing number of cell phones will cause cancer because of the energy of the radio waves they emit. cell phones are a new technology that only recently became widely used. and because cancer takes years to develop, the amount of risk is not yet known. research this issue, and summarize what’s known so far. in your summary, include information about the energy of radio waves. be sure to only use credible sources. based on what you learned from your research, do you think people should limit their cell phone use? why or why not?

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.
