Living in one place for my entire life has opened my eyes to the world and the people around me. In my home, like most others, doing well in school, being responsible, and going to a good college is important to build and maintain a trust with my parents. Unlike most of my friends, and really the majority of teenagers, I am always motivated to study and work hard in order to get things done, for I know that doing so will ultimately get me accepted to a good college, and most importantly, allow me to have a successful career and life.

YAY

Sirens escape echoing speakers, piercing my mind like hollow tip rounds. It was an obnoxious operation of cooperation between that and the blinding brightness of red and blue as pollutants to the sky. It exhibited such cooperation that it could instill fear into any man; absent ability to hear or even absent sight. I had taken part in many wild stunts in my life. Some, you could even call obscenities. Though, none unveiled a curtain of fear as this. Atom-like thoughts bounced around my head like that within an unknown gas. Questions like, ?How could I be so wrong!?! How could- could they be so right,? and, ?How am I supposed to think with this impossible, shrieking screech!?!?

1. The half-life of Carbon-14 decaying to Nitrogen-14 is 5,730 years. A mammoth bone fossil found in Siberia appears to be 22,920 years old. If these fossils now contain 6 grams of C-14, how much C-14 did they contain when this mammoth died? 22,920 6 17,190 12 11,460 24 5,730 48 1 96 22,920 / 5,730 = 4 half lives OR end = starting amount / 2 ^ half-lives 6 = start / 2 ^ 4 6 = start / 16 96 = starting amount 2. A disease is controlled by a single gene with two alleles. Assume Hardy-Weinberg equilibrium for this gene. If one in 2,000 monkeys have albinism, what is the ratio of heterozygous carriers to those with the disease? P^2 + 2pq + q^2 = 1

IB Biology Evolution We are all related, one big family in the ?tree of life? We are not just a HUMAN FAMILY ? we are a LIVING family Evolution Do you mean the yeast are OUR distant cousins? Some thoughtful questions? What happened when scientist Paul Nurse added human DNA to the yeast cells? What does this indicate about the evolutionary history of yeast and humans? An interactive website for you to go to Standard 5.4.1 Define Evolution The cumulative change of heritable characteristics of a population Cumulative change ? small changes upon small changes that add up to large changes over long time scales and many generations! Heritable characteristics ? traits controlled by the genes Population ? not an individual 5.4.2

Chapter 22 pages 428 ? 430 What is the full name of the book that Darwin published and what was the date of publication? What are the four manners in which this book focused biologists? attention on the great diversity of organisms? What are the two points that Darwin made in his book? What is natural selection? What is the result of natural selection? In what two ways did this book ?rock the house,? in other words why was it truly radical? What was the conventional paradigm (the prevailing view) of life at the time of Darwin?s publication? Plato was one of the philosophers that had great influence on western culture. What was Plato?s view of life? How about Aristotle, what was his view? Explain the philosophy that dominated biology in the 1700s.
