Organism Emergent Properties- Novel properties that emerge as each step up the hierarchy of biological order is taken. Reductionism- Reducing complex systems to simpler components that are more manageable to study. Cells- The lowest level of structure capable of performing all the activities of life‚ all organisms are composed of cells which are the basic units of structure

Robert Brown is credited with the discovery of the cell nucleus. 4. Schleiden and Schwann’s contribution to biology was proposing that cells are the basic structural unit for plants and animals. 5. Before Virchow‚ one idea was that living things could arise from non-living and from dead matter‚ a process called ‘spontaneous generation’. 6. Person B is more

Lab: Inhibiting the Action of Catechol Oxidase By: Kimberly G. Introduction: In this lab‚ Mr. Greene ’s sixth period AP Biology class split into groups "to investigate inhibition of enzyme activity by specific chemicals called inhibitors" (1). Group three pondered this lab ’s inhibitor‚ phenylthiourea (PTU). Is it a competitive inhibitor? That is an inhibitor that literally "competes" with the substrate by mimicking it‚ and thus "wins" the position at the active site of the enzyme. The blocked

Biology Major substances: Organic compounds – are compounds that contain carbon and were originally made by living things e.g. carbohydrates‚ lipids‚ proteins‚ nucleic acids Inorganic compounds – are compounds do not contain carbon as a main element Organic compounds | Composition | Function | Proteins | Carbon‚ hydrogen‚ oxygen and nitrogen | Used in the structure‚ storage‚ movement and transport of cells for growth and repair. | Lipids | Carbon‚ hydrogen and oxygen | Stores energy

Reading Guide for Chapter 35 – The Vertebrates 1. What are the five features of the chordates? • A hollow dorsal nerve cord just beneath the dorsal surface of the animal. In vertebrates this differentiates into the brain and spinal cord. • A flexible rod called the notochord that’s on the dorsal side of the primitive gut in the early embryo‚ present at some developmental stage in all chordates‚ located just below the nerve cord. May persist in some chordates; in others‚ it is replaced by

Frederick Griffith | This person made an experiment that involved injecting mice with pneumonia: smooth S cells‚ rough R cells‚ heat-killed S cells‚ and heat-killed S cells with living R cells. | Avery‚ McCarty‚ and MacLeod | First to show that DNA was the genetic material‚ but not believed. Repeated Griffith’s experiment‚ but subjected the strains to different enzymes‚ isolating RNA‚ DNA‚ lipids‚ carbohydrates‚ and proteins. Only the DNA killed the mice; the others had the mice survive. | Hershey

Test 1 Study Guide 1. Respiration * Respiration * Gas exchange * Necessary because cells require oxygen. * Exchanging O2 and CO2 * Carbon Dioxide is a waste product and must be removed from the body. * Internal respiration = gas exchange at the cellular level. * Oxygen diffuses from the blood into the tissue cells. * External respiration = gas exchange at the alveoli level. * Oxygen from the inhaled air diffuses into the blood in the pulmonary
