Biology Paper
The article I chose was from seattletimes.com, and was entitled “Study: Stem cells mutate.” This article was about how, like ordinary cells, embryonic stem cells can develop genetic mutations over time. Contrary to what scientists once though, stem cells, though able to self-replenish, do not remain “ageless and perpetually unblemished.” According to a study by an international team of scientists, stem cells can develop potentially harmful mutations over time. And if these mutated stem cells

Biology Summary
We have known for centuries that traits are passed from parents to offspring. What has not always been understood is how traits are determined. One explanation that appealed to scientist for many centuries was that traits of parents were blended, or mixed in offspring. The blending hypothesis accounted for many observable traits and was widely accepted for many years. However, the idea of blending could not account for the appearance of unexpected traits in some
