Peter Dang Mrs. Truesdell AP Biology Period 5 2 October 2013 CHAPTER 7 STUDY GUIDE AN OVERVIEW OF PHOTOSYNTHESIS Autotrophs are plants that can feed themselves by making their own food. Photo-autotrophs are organisms that produce organic molecules from inorganic molecules using the energy of light. Producers are when plants make their own organic molecules. A redox reaction is oxidation and reduction. Photosynthesis takes water and carbon dioxide to make glucose and oxygen. Cellular respiration

Women in the military have a history that extends over 400 years into the past‚ throughout a large number of cultures and nations. Women have played many roles in the military‚ from ancient warrior women‚ to the women currently serving in conflicts‚ even though the vast majority of all combatants have been men in every culture. Even though women serving in the military has often been controversial‚ relatively few women in history have fought alongside men. In the American Civil War‚ there were a

Chapter 3 Molecules of Life I. Carbon 1. 6 electrons- (4 valence) has the ability to bond with 4 other elements 2. Hydrocarbons- (contains only C & H) 3. Asymmetric carbon- attached to 4 different atoms or groups of atoms II. Isomers - Compounds having the same molecular formula but different structure and properties 1. Structural- differ in covalent arrangement of their atoms and may differ in location of double bonds 2. Geometric- same structure different arrangement 3. Enantiomer/stereoisomer

"We serial killers are your sons‚ we are your husbands‚ we are everywhere. And there will be more of your children dead tomorrow." - Ted Bundy. Serial killers have long been the taboo of society since the beginning of time. The horror movie industry portrays serial killers through scary masks‚ or a maniac running around the streets with a knife; but the truth is most serial killers are introverted and were once abused as children. Serial killers are not born serial killers they are influenced at

1. Human population growth prehistoric times to the present…. a. Has slowed considerably over the last 50 years b. Follows an S-shaped curve. c. Has been strongly influenced by density-dependent factors d. Exhibits large oscillation around K e. Roughly fits an exponential curve 2. The experimental design used in the Ribeiroia limb abnormality study ensured that the individuals handling the tadpoles‚ examining the adult frogs and compiling the data did not know which treatment (if any)

To study biomedical engineering has been my dream. Einstein distinguished science from engineering when he explained‚ "Scientists investigate that which already is; engineers create that which has never been.". I wish to pursue a career in biomedical engineering as it is a great way of being involved in both fields of engineering and medicine. My desire to study biomedical engineering had been driven by the desire to treat diseases through the help of modern technology. I was always been fascinated

Evolution by natural selection is slow but can be observed in certain situations. How to spot evolution in real time: Artificial selection – manipulation by humans such as breeding dogs or growing corn. Repro-rate – rate of reproduction. Stochastic Event: unexpected disaster like a volcano eruption or tornado. (Research geological time) LIVING THINGS: Biology – Study of living things. Living things – all the organisms descended from a single-celled ancestor. * Characteristics:

I. A. Neutral Evolution 1. Kimura 1968 2. Proposed much of genetic variation is neutral 3. Neutral mutations do not affect phenotype a) Either do not alter product of gene b) Affect non-coding regions of DNA 4. Not subject to natural selection 5. Useful for reconstructing phylogenies B. Speciation 1. Formation of new species from ancestral species 2. 2 components a) genetic isolation b) Genetic divergence 3. Adds new branch to the tree of life C. Species Concept 1. Evolutionary independent
