Study Guide Biology
Subject:
Biology Semester 1 Final Study Guide A group of students wants to determine if different types of music affect the growth rate of plants. They expose one group to two hours of classical music, a second group to two hours of rock music, a third group to country music, and a fourth group to no music. Identify the following: independent variable, dependent variable, constants, and control. What are the 3 principles of the cell theory? Compare and contrast animals and plant cells. Animal Cells Plant Cells Describe the functions of nucleus, ribosome, chloroplast, mitochondria, endoplasmic reticulum, and golgi apparatus. Draw the cell membrane and label the proteins, phospholipids, cholesterol and carbohydrates.

Lecture Presentations byNicole Tunbridge and Kathleen Fitzpatrick Chapter 5The Structure and Function of Large Biological Molecules 1 The Molecules of Life All living things are made up of four classes of large biological molecules: carbohydrates, lipids, proteins, and nucleic acids Macromolecules are large molecules and are complex Large biological molecules have unique properties that arise from the orderly arrangement of their atoms ? 2017 Pearson Education, Inc. Concept 5.1: Macromolecules are polymers, built from monomers A polymer is a long molecule consisting of many similar building blocks The repeating units that serve as building blocks are called monomers Carbohydrates, proteins, and nucleic acids are polymers ? 2017 Pearson Education, Inc.

AP biology test bank chp 14
Subject:
Campbell's Biology, 9e (Reece et al.) Chapter 14 Mendel and the Gene Idea The questions in Chapter 14 are mostly at the Application/Analysis skill level. The material in the chapter invites students to apply Mendel?s laws, and by doing so encourages problem solving. Because of the human-related Concept 14.4, a fair number of Synthesis/Evaluation questions are included as well. Very little of the chapter lends itself to Knowledge/Comprehension questions only. In addition, to help students make maximum use of information presented about one or more specific traits, a greater number of questions than usual is grouped together to explore brief scenarios or figures. Multiple-Choice Questions 1) What do we mean when we use the terms monohybrid cross and dihybrid cross?
Solubility rules
Subject:
Solubility Rules 1. All common salts of the Group 1 elements and ammonium ion are soluble. 2. All common acetates and nitrates are soluble. 3. All binary compounds of Group 17 elements (other than F) with metals are soluble except those of silver, mercury(I), and lead. 4. All sulfates are soluble except those of barium, strontium, lead, calcium, silver and mercury(I). 5. Except for those in Rule 1, carbonates, oxides, sulfides, and phosphates are insoluble. 6. Oxides and peroxides are always written in molecular form. 7. Gases are always written in molecular form. 8. The only strong bases are the hydroxides of Group I & II metals except beryllium. 9. The only strong binary acids are those of chlorine, bromine, and iodine.
AP Bio_dna_replication
Subject:
DNA Replication: A Closer Look * The copying of DNA is remarkable in its speed and accuracy * More than a dozen enzymes and other proteins participate in DNA replication Getting Started * Replication begins at particular sites called origins of replication, where the two DNA strands are separated, opening up a replication ?bubble? * A eukaryotic chromosome may have hundreds or even thousands of origins of replication * Replication proceeds in both directions from each origin, until the entire molecule is copied * At the end of each replication bubble is a replication fork, a Y-shaped region where new DNA strands are elongating * Helicases are enzymes that untwist the double helix at the replication forks * Single-strand binding proteins bind to and stabilize single-stranded DNA
AP Bio_dna_is_genetic_material
Subject:
The Molecular Basis of Inheritance Life?s Operating Instructions * In 1953, James Watson and Francis Crick introduced an elegant double-helical model for the structure of deoxyribonucleic acid, or DNA * Hereditary information is encoded in DNA and reproduced in all cells of the body * This DNA program directs the development of biochemical, anatomical, physiological, and (to some extent) behavioral traits * DNA is copied during DNA replication, and cells can repair their DNA Concept 16.1: DNA is the genetic material * Early in the 20th century, the identification of the molecules of inheritance loomed as a major challenge to biologists The Search for the Genetic Material: Scientific Inquiry
AP Bio_chromosomal_structure_and_dieases
Subject:
Alterations of chromosome number or structure cause some genetic disorders * Large-scale chromosomal alterations in humans and other mammals often lead to spontaneous abortions (miscarriages) or cause a variety of developmental disorders * Plants tolerate such genetic changes better than animals do Abnormal Chromosome Number * In nondisjunction, pairs of homologous chromosomes do not separate normally during meiosis * As a result, one gamete receives 2 of the same type of chromosome, and another gamete receives no copy * Aneuploidy results from the fertilization of gametes in which nondisjunction occurred * Offspring with this condition have an abnormal number of a particular chromosome * A monosomic zygote has only 1 copy of a particular chromosome
