Asexual Reproduction

...Asexual reproduction Asexual reproduction is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only; it is reproduction which almost always does not involve meiosis, ploidy reduction, or fertilization. The offspring will be exact genetic copies of the parent, except in the specific case of automixis. A more stringent definition is agamogenesis which is reproduction without the fusion ofgametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea, bacteria, and protists. Many plants and fungi reproduce asexually as well. While all prokaryotes reproduce asexually (without the formation and fusion of gametes), mechanisms for lateral gene transfer such asconjugation, transformation and transduction are sometimes likened to sexual reproduction.[1] A complete lack of sexual reproduction is relatively rare among multicellular organisms, particularly animals. It is not entirely understood why the ability to reproduce sexually is so common among them. Current hypotheses [2] suggest that asexual reproduction may have short term benefits when rapid population growth is important or in stable environments, while sexual reproduction offers a net advantage by allowing more rapid generation of genetic diversity, allowing adaptation to changing environments. Developmental constraints[3] may underlie why few animals have relinquished sexual reproduction completely in their......

EVOLUTION CONNECTION Life before and after Oxygen 91 102 103 Aerobic versus Anaerobic Lifestyles BIOLOGY AND SOCIETY Marathoners versus Sprinters Track-and-field athletes usually have a favorite event in which they excel. Some runners specialize in sprints of 100 or 200 meters. Others excel at longer races of 1,500, 5,000, or even 10,000 m. It is unusual to find a runner who competes equally well in both 100-m and 10,000-m races; most runners are more comfortable running races of particular lengths. It turns out that there is a biological basis for such preferences. The muscles that move our legs contain two main types of muscle fibers: slow-twitch and fast-twitch. Slow-twitch muscle fibers can contract many times over a longer period but don’t generate a lot of quick power for the body. They perform better in endurance exercises requiring slow, steady muscle activity, such as marathons. Fast-twitch muscle fibers can contract more quickly and powerfully than slow-twitch fibers but......

...Chapter 8 Individual Income Tax Computation and Tax Credits SOLUTIONS MANUAL Discussion Questions 1. [LO 1] What is a tax bracket? What is the relationship between filing status and the width of the tax brackets in the tax rate schedule? A tax bracket is a range of taxable income that is taxed at a specified tax rate. Because only the income in the particular range is taxed at the specified rate, tax brackets are often referred to as marginal tax brackets or marginal tax rates. The level and width of the brackets depend on the taxpayer’s filing status. The tax rate schedules include seven tax rate brackets. The rates for these brackets are 10%, 15%, 25%, 28%, 33%, 35%, and 39.6%. In general, the tax brackets are widest for Married filing jointly (for example, more income is taxed at 10%), followed by Head of household, Single, and then Married filing separately (the brackets for Married filing separately are exactly one-half the width of the brackets for Married filing jointly, and the width of the 10% and 15% brackets for Single and Married filing separately are the same). 2. [LO 1] In 2014, for a taxpayer with $50,000 of taxable income, without doing any actual computations, which filing status do you expect to provide the lowest tax liability? Which filing status provides the highest tax liability? For a taxpayer with $50,000, the married filing jointly filing status should provide the lowest tax liability in 2014 because the MFJ tax rate schedule......

...Solutions to Questions 8-1 Activity-based costing differs from tradi-tional costing systems in a number of ways. In activity-based costing, nonmanufacturing as well as manufacturing costs may be assigned to products. And, some manufacturing costs—including the costs of idle capacity—may be excluded from prod-uct costs. An activity-based costing system typically includes a number of activity cost pools, each of which has its unique measure of activity. These measures of activity often differ from the allocation bases used in traditional costing systems. 8-2 When direct labor is used as an allocation base for overhead, it is implicitly assumed that overhead cost is directly proportional to direct labor. When cost systems were originally devel-oped in the 1800s, this assumption may have been reasonably accurate. However, direct labor has declined in importance over the years while overhead has been increasing. This suggests that there is no longer a direct link between the level of direct labor and overhead. Indeed, when a company automates, direct labor is replaced by machines; a decrease in direct labor is accompa-nied by an increase in overhead. This violates the assumption that overhead cost is directly propor-tional to direct labor. Overhead cost appears to be driven by factors such as product diversity and complexity as well as by volume, for which direct labor has served as a convenient measure. 8-3 Top managers provide leadership that is needed to properly motivate...

...Biology » Outlines Chapter 21 - The Genetic Basis of Development Chapter 21 The Genetic Basis of Development Lecture Outline Overview: From Single Cell to Multicellular Organism * The application of genetic analysis and DNA technology to the study of development has brought about a revolution in our understanding of how a complex multicellular organism develops from a single cell. * In 1995, Swiss researchers identified a gene that functions as a master switch to trigger the development of the eye in Drosophila. * A similar gene triggers eye development in mammals. * Developmental biologists are discovering remarkable similarities in the mechanisms that shape diverse organisms. * While geneticists were advancing from Mendel’s laws to an understanding of the molecular basis of inheritance, developmental biologists were focusing on embryology. * Embryology is the study of the stages of development leading from fertilized egg to fully formed organism. * In recent years, the concepts and tools of molecular genetics have reached a point where a real synthesis of genetics and developmental biology has been possible. * When the primary research goal is to understand broad biological principles, the organism chosen for study is called a model organism. * Researchers select model organisms that are representative of a larger group, suitable for the questions under investigation, and easy to grow in the lab. * For......

Her simple motto: "You can't run a company efficiently with a 'bunch of babies.' If you don't like it, leave. This is not a prison." Advice to other senior managers, be tough.
