Carl Kogstrom Neuberg IB MYP Biology 9 May 2014 Effects of Genetically Modified Food Genetically modified food contributes a major portion to the world’s food supply. Genetically modified food (GMF) is food that is produced from plants or animals that have had artificial changes to their genetic material. GMFs have been tested and experimented on since 1992 and sold commercially since 1994. The DNA of crops has been altered to make them grow faster as well as resist many different pesticides. This

Stride Rate and Length Although strides vary greatly among runners‚ a few studies have worked to quantify differences in stride rate between barefoot and shod runners. They have concluded that an elite shod runner usually has a stride frequency between 170-180 steps per minute even at low speeds such as 2.75 m∙s-1. On the other hand‚ nonelite runners often fall in the range of 150-160 steps per minute at similar speeds. Barefoot or minimally shod runners are often characterized by shorter strides

EVOLUTION and NATURAL SELECTION (30 pts) a. What is a mutation? Provide 3 examples of different mutations causing specific diseases in human population. For each example explain what kind of mutation that is (ie. A point substitution‚ a chromosomal duplication etc). Mutation is a genetic mistake(s) that occur during DNA replication. 1. Progeria accelerated aging; mutation in the LMNA gene 2. Hypertrichosis excessive hair on the shoulders‚ face and ears; implicate it to a rearrangement

Life story on the man behind genetics Johann Gregor Mendel was a biologist and ordained priest who conducted experiments in heredity. He used his resources at his monastery to grow thousands of pea plants‚ keeping detailed records and calculations that debunked the previous theory of “trait blending.” Although people largely didn’t recognize his work during his lifetime‚ his lengthy research showed that characteristics can be dominant or recessive and are passed on independently. These facts transformed
