Danielle Christian AP Bio FRQ #2 January 22nd‚ 2013 A.) Graph #1 A.) Calculation The rate of reaction from 0-30 minutes is 0.34667; r=10.4μM /30 minutes B.) Explanation The reaction was observed after 30 minutes because the reaction rate eventually slows down and the enzyme reaches its maximum potential. Since the enzyme is using the substrate so quickly‚ the substrates concentration depletes. That means the rate will slow down. Our graph shows that after about 40 minutes‚ the enzyme

AP Bio DNA‚ RNA‚ Protein synthesis Study Guide DNA Structure Nucleotide structure - sugar‚ phosphate group‚ base backbone structure - alternating sugar and phosphate group directionality (5’-3’) - DNA is anti parallel. The side that sticks out s the 5’ side bases - adenine = thymine & guanine=cytosine purines vs Pyrimidines - purines have two rings while pyrimidines have one ring Bonding - hydrogen bonds Base Pairing rules - look at bases ^^ DNA Replication Semi-conservative replication

Free Response When the dog first barks it creates sound waves that travel through the air‚ spreading out and dissipating as they go‚ until they reach the ear of the musician. When the sound waves reach the musician they are “gathered up” into the ear by the oracle and travel into the middle ear. Once in the middle ear the sound waves vibrate the ear drum which transfers the vibrations to the hammer. The hammer then moves the vibrations on to the anvil which transfers them to the stirrup.

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

Observing Ecosystems Ecosystems-The sums of all the organisms living within its boundaries and all the abiotic factors with which they interact. Chemical Elements such as carbon and Nitrogen are cycled among abiotic and biotic components of the ecosystem. Photosynthetic organisms assimilate these elements in inorganic form from the air‚ soil‚ and water and incorporate them into their biomass‚ some of which is consumed by animals. Both energy and matter are transformed in ecosystems throught

inherited ability to recognize certain pathogens. Plants respond to the environment. Examples are touch‚ light and gravity. Through photoreceptors they can detect light‚ its direction‚ intensity and wavelength. Most responses are triggered due to plant hormones. Tropism is any type of response that results in curvature of of organs toward or away from a stimulus (ex. Light). Plants reproduce by pollination‚ also called fertilization‚ which is the transfer of pollen from an anther to a stigma. A pollen

Cells are not smaller that 0.1 um because within the cell all the necessary components have to take place‚ cellular metabolism‚ reproduction‚ photosynthesis and there has to be a sufficient amount of space for that to
