Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules

Monuments are an irreplaceable way in which individuals throughout the world commemorate the triumphs of heroes or disastrous events. When devising a monument‚ individuals often disregard three critical factors; the location‚ size and material of the monument. Location‚ size and material must be utilized in preciseness to obtain optimum success. The precision of where a monument is to be erected must be precise in order to gain maximum appreciation.

focus on chemical signals. 1. External signals are converted to responses within the cell a. Evolution of cell signaling i. In yeast a cells and αcells both secrete chemicals‚ which can only be received by the alternate type yeast. This signals the two cells to join via fusion 1. The process by which the signal on the surface of the cell is converted to a series of steps by the cell in response is called a signal transduction pathway ii. Signal transduction

AP LITERATURE OPEN RESPONSE QUESTIONS 2011: In a novel by William Styron‚ a father tells his son that life “is a search for justice.” Choose a character from a novel or play who responds in some significant way to justice or injustice. Then write a well-developed essay in which you analyze the character’s understanding of justice‚ the degree to which the character’s search for justice is successful‚ and the significance of this search for the work as a whole. 2010: Palestinian American literary theorist

potential" (Ψ) is a measure of the free energy of water; pure water (which has a high amount of free energy) is arbitrarily assigned a water potential of zero; units pressure: MPa; can be positive or negative factors that determine plant water potential: 1) amount of solutes- increasing concentrations will lower the free energy (water potential); termed osmotic potential (ψs) 2) turgor pressure (ψp) in plant cell- positive pressure inside plant cells; increases free energy; loss of turgor = wilting
