bioJared Kerr Chapter 7 Section 2 I. Aerobic Respiration a. Overview of aerobic 1. Aerobic respiration has two major stages; the Krebs Cycle and the electron transport chain. 2. In the Krebs cycle‚ the oxidation of glucose that began with glycolysis is completed. 3. In the electron transport chain‚ NADH is use to make ATP. 4. In prokaryotes the reactions take place in the cytoeol. 5. In eukaryotes the reactions take place in the mitochondria. 6. The mitochondrial

Summary of Reading – Chapter #2 Chapter 2 of The New Jim Crow focuses on how the system of mass incarceration works. Alexander concentrates on the "War on Drugs‚" because "convictions for drug offenses are the single most important cause of the explosion in incarceration rates in the United States." Early on‚ she exposes myths‚ noting that the war is not "aimed at ridding the nation of drug ’kingpins’ or big-time drug dealers‚" and the drug war is not "principally concerned with dangerous drugs"

Biology – Chapter 1 Study Guide The goal of science is to try to understand the world around us. Scientists often work in groups so they can exchange data‚ which is extremely important in the study of science. Understanding of science and the scientific approach is essential to intelligent decision making because it would make scientists make reasonable decisions and conclusions. A control is the experiment set-up not containing any independent variable. Analyzing data and drawing

Week #1 -autotrophs are organisms that harvest light or chemical energy in organic compounds. They self nutrition -heterotrophs are organisms that get complex nutrients from the environment (by eating other organisms) -Fungi are heterotrophs or predators because they are parasitic. Bread mold secretes digestive enzymes to enter the membrane. Same as foot fungus‚ it extends hyphae (fungal branches) into the cells to absorbs nutrients -One fungus makes traps for nematode worms while another fungus

Evolution Evolution- change in a population over time Charles Darwin: A Naturalist (type of biologist) Sailed with an explorer on the HMS Beagle to the Galapagos Island in 1831 (22 years old) He observed Turtles: On the island they were huge and had to eat food up high (the neck would extend) over time‚ the shell changed. The ones with the short necks died off because of lack of food Published the book: Origin of Species By Means of Natural Selection (to beat Wallace) He’s Catholic Owen-

\ Chapter 23 Reading guide 1. what is the smallest unit of evolution and why is this important to understand? The population is the smallest unit of evolution . This is important to understand because it keeps clear what is evolving. 2. Define the following terms: a. Microevolution: evolutionary change below the species level; change in the genetic makeup of a population from generation to generation. It is evolutionary change on its smallest scale b. Population: a localized group

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
