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?

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.

Factors that can increase mutation rates a. high temps b. low temps c. food additives d. uv rays
