Peter Dang Mrs. Truesdell AP Biology Period 5 2 October 2013 CHAPTER 7 STUDY GUIDE AN OVERVIEW OF PHOTOSYNTHESIS Autotrophs are plants that can feed themselves by making their own food. Photo-autotrophs are organisms that produce organic molecules from inorganic molecules using the energy of light. Producers are when plants make their own organic molecules. A redox reaction is oxidation and reduction. Photosynthesis takes water and carbon dioxide to make glucose and oxygen. Cellular respiration

Guided Inquiry • Skills Lab Chapter 11 Lab Modeling Meiosis Problem How does meiosis increase genetic variation? Introduction Most cells in organisms that reproduce sexually are diploid. They have two sets of chromosomes and two complete sets of genes. Gametes are an exception. Gametes are the cells that combine during sexual reproduction. In animals‚ these cells are called sperm and eggs. Gametes are haploid cells with only one set of chromosomes. Meiosis is the process in which haploid
Premium Chromosome Meiosis
Meiosis I Prophase I: - nuclear membrane dissolves * centrioles move to poles * spindle fibres forming * DNA has been replicated and forms chromosomes made of 2 identical chromatids * Homologous chromosomes line up to form a bivalent‚ 2 chromosomes or 4 chromatids (TETRAD)‚ this process is called SYNAPSIS * Where chromatids overlap is called a CHIASMATA‚ and it allows for CROSSING OVER of genetic information between chromosomes Metaphase I: - homologous chromosomes

Exercise 4 Lab Report (3) Individual: Prepared blood slide (a.) Compare red and white blood cells - what cellular features are present in white cells but not in red blood cells and vice versa? Include a digital image of the blood cells present in the permanent dry. Red Blood cells carry hemoglobin inside of them which helps carry oxygen from the lungs to the rest of the body. Hemoglobin is what gives blood cells the red pigmentation. The amount of blood cells present in the blood give it

Kinesiology 303 Lab Vertical and Horizontal Power Lab Write up Introduction: Running and jumping competitions have taken place for centuries‚ dating as far back as the first Olympian games. These physical competitions measured individual’s prowess‚ but also competing for power to rule or show their masculinity. Today‚ in modern times‚ this is synonymous to individuals who are judged on their highest jump and fastest 40-yard dash time as part of the National Football League draft‚ which combine

What are the names of the species used in this experiment? Which of these species was the most tolerant of increased acidity in the aquarium? Which species was the least tolerant? The names of the species used in the experiment were clam‚ dragonfly‚ and side swimmer. The specie that was the most tolerant was the dragonfly and the least tolerant was the clam. Describe how acid precipitation affects ecosystems. Acid precipitation affects the ecosystem‚ for example‚ lowering ph in water when it

CHAPTER 14 1. Norm of reaction: the phenotypic range that a genotype is associated with due to environmental influences. 2. Multifactorial: characters that have many factors‚ both genetic and environmental‚ collectively influence phenotype. 3. Pleiotropy: when a gene controls multiple phenotypic effects 4. Epistasis: When a gene at one locus alters the phenotypic expression of a gene at a second locus 5. Carrier: a person who is heterozygous for a recessive disease and therefore

Title: studying organisms in an ecological habitat Aim: to determine the feeding relationships in an ecological habitat Method: * Explore ecological habitat * Make notes of features of selected habitat * Measure the seize of the area to be explored * Record the name of all organisms found in the habitat * Make note of any special features of the organisms * Note the presence of any symbiotic relations Observations and results: Tabulation of the organisms in habitat

“too acidic to justify the worth of drinking every morning for the miniscule amounts of vitamin C it contains” (Dr. Kenny and Henderson). It has been found that orange juice‚ while it does contain vitamin C‚ does not contain enough vitamin C to live up to the “super food” standard that was set for it in the past. Instead of assisting one’s immune system‚ it has now been discovered that due to the naturally high acidity of orange juice‚ they actually are detrimental to ones health. Drinking orange
