AP Biology Sunday‚ October 24‚ 2010 Enzyme Lab Write-Up Purpose: To observe how an enzyme affect the speed of chemical reaction. To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of

AP Biology Name: Chapter 51 Guided Reading 1. How do behavioral ecologists define behavior? Behavioral ecologists define behavior as everything an animal does and how it does it 2. What is the focus of: a. Proximate questions of behavior? Focuses on the environmental stimuli‚ if any‚ that trigger a particular behavioral act‚ as well as the genetic‚ physiological‚ and anatomical mechanisms underlying it. b. Ultimate questions of behavior? Focuses on the evolutionary significance

Ecology Unit Study Guide AP Biology Study Guide: Read through these concepts. If you are not sure of what the concept is or means search for the answer in your textbook and write it on a separate sheet of paper. If you know these terms you should do well on the test. Chapter 52 – Ecology and the Biosphere 1. Distinguish among the following types of ecology: organismal‚ population‚ community‚ ecosystem‚ and landscape. 2. Explain how dispersal may contribute to a species’ distribution.

INTRODUCTION Levels of organization (cell to biosphere) and characteristics of life Levels: Cells->tissue ->organs & organ systems->organisms->populations->communities->ecosystems-> biosphere Characteristics of life: Cell and Organization: Each cell can only do the job it is tasked with. Example: brain cells Energy Use and Metabolism: Energy is needed many organisms. Energy is utilized in chemical reactions Response to Environmental Changes: responds to stimuli Regulation and Homeostasis: ex:

ECOSYSTEMS BIODIVERSITY- the variety of life on Earth and the essential interdependence of all living things. Three components of biodiversity; 1. Genetic- variety within species 2. Species- all different species 3. Ecosystems- can support diversity Advantages of biodiversity Oxygen Food Clean water Medicine Aesthetics Intrinsic vs Utilitarian value Intrinsic value is something that has value in and of itself Utilitarian value is the value something has‚ as a means

What are the differences between the four common types of organic molecules? 6. Why do cells make ATP? 7. How can you distinguish between prokaryotic and eukaryotic cells‚ and between haploid and diploid cells? What types of cells fall into these categories? 8.

Genes and Genetics 1. 2. each chromosome exists as two genetically identical chromatids attached to their centromere. Each chromosome appears as two chromatids attached to a centromere. In the first meiotic division chromosomes align in homologous pairs. Points of contact form between members of the same homologous pair. The points of contact or crossing over between members of a homologous pair are the chiasmata. 3. The homologous pairs move to the equator of the cell. Equal lengths of the

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
