Unit1: Cell functions/ Cell division Cells Cell theory: -All living things are composed of one or more cells. -The cell is the smallest entity that retains the properties of life. -New cells arise only from cell that already exists. Structure of the cell: The outer boundary (plasma membrane) similar to a city wall It is constructed with molecules called lipids (fat and oils) The cell membrane is composed of: -Proteins and Lipids -FUNCTION: to allow molecules into and out of the

Chapter 29 An Overview of Land Plant Evolution 1. Describe four shared derived homologies that link charophyceans and land plants. a. The complexes that produce cellulose are rose shaped in both charophyceans and land plants. Next both have peroxisome enzymes that help minimize the loss of organic products from photorespiration. The structure of their flagellated sperm is very similar. Finally‚ both form a phragmoplast during cell division. 2. Distinguish among the kingdoms Plantae‚ Streptophyta

AP Biology notes: Chapter 2- The Chemical Context of Life 1. Overview * The bombardier beetle fights the ants that plague it by using chemistry. * The natural systems and environment that organisms live in involves chemistry and physics. * Biology is not the only category of science. There is also chemistry‚ physics‚ and engineering. * Organization of life is separated into a hierarchy of structural levels. 2. Elements and Compounds * Matter- anything that takes up

Why are some colors of light more effective than other colors? Answer Photosynthetic saturation is the maximum rate of photosynthesis. What was the value for photosynthetic saturation in tomato leaves? Answer Light quality does not effect the rate of photosynthesis. Answer Based on what you know about photosynthesis‚ provide possible reasons for what causes photosynthetic saturation (these cannot be determined from the graph). Answer Which color

1. The handicaps the Federalists and Adams had running in the election of 1800 was their Alien and Sedition Act arousing a host of enemies‚ although most of these critics were dyed-in-the-wool Jeffersonians anyhow. Also‚ the refusal of Adams to give them a rousing fight with France was a handicap. 2. The Federalists attacked Jefferson in a " whisper campaign" by accusing him of having robbed a widow and her children of a trust fund and of having fathered numerous mulatto children by his own slave

AP Chemistry Lab 2: Analysis of Alum Lab Objective: In this lab we will analyze alum by two techniques in order to verify its identity. The melting point and the mole ratio of hydrated water to anhydrous aluminum potassium sulfate will be determined. Lab Procedure: 1. Use a mortar and pestle to crush alum. 2. Pack the alum in capillary tube‚ and then fasten it to the thermometer. 3. Fasten the thermometer to the ring stand. 4. Immerse the bottom of the
