| pearson meiosis: Multiple Representations in Biological Education David F. Treagust, Chi-Yan Tsui, 2013-02-01 This new publication in the Models and Modeling in Science Education series synthesizes a wealth of international research on using multiple representations in biology education and aims for a coherent framework in using them to improve higher-order learning. Addressing a major gap in the literature, the volume proposes a theoretical model for advancing biology educators’ notions of how multiple external representations (MERs) such as analogies, metaphors and visualizations can best be harnessed for improving teaching and learning in biology at all pedagogical levels. The content tackles the conceptual and linguistic difficulties of learning biology at each level—macro, micro, sub-micro, and symbolic, illustrating how MERs can be used in teaching across these levels and in various combinations, as well as in differing contexts and topic areas. The strategies outlined will help students’ reasoning and problem-solving skills, enhance their ability to construct mental models and internal representations, and, ultimately, will assist in increasing public understanding of biology-related issues, a key goal in today’s world of pressing concerns over societal problems about food, environment, energy, and health. The book concludes by highlighting important aspects of research in biological education in the post-genomic, information age. |

| pearson meiosis: Molecular Biology Nancy Craig, Rachel Green, Orna Cohen-Fix, Carol Greider, Gisela Storz, Cynthia Wolberger, 2014-05 The biological world operates on a multitude of scales - from molecules to tissues to organisms to ecosystems. Throughout these myriad levels runs a common thread: the communication and onward passage of information, from cell to cell, from organism to organism and ultimately, from generation to generation. But how does this information come alive to govern the processes that constitute life? The answer lies in the molecular components that cooperate through a series of carefully-regulated processes to bring the information in our genome to life. These components and processes lie at the heart of one of the most fascinating subjects to engage the minds of scientists today: molecular biology. Molecular Biology: Principles of Genome Function, Second Edition, offers a fresh approach to the teaching of molecular biology by focusing on the commonalities that exist between the three kingdoms of life, and discussing the differences between the three kingdoms to offer instructive insights into molecular processes and components. This gives students an accurate depiction of our current understanding of the conserved nature of molecular biology, and the differences that underpin biological diversity. Additionally, an integrated approach demonstrates how certain molecular phenomena have diverse impacts on genome function by presenting them as themes that recur throughout the book, rather than as artificially separated topics As an experimental science, molecular biology requires an appreciation for the approaches taken to yield the information from which concepts and principles are deduced. Experimental Approach panels throughout the text describe research that has been particularly valuable in elucidating difference aspects of molecular biology. Each panel is carefully cross-referenced to the discussion of key molecular biology tools and techniques, which are presented in a dedicated chapter at the end of the book. Molecular Biology further enriches the learning experience with full-color artwork, end-of-chapter questions and summaries, suggested further readings grouped by topic, and an extensive glossary of key terms. Features: A focus on the underlying principles of molecular biology equips students with a robust conceptual framework on which to build their knowledge An emphasis on their commonalities reflects the processes and components that exist between bacteria, archae, and eukaryotes Experimental Approach panels demonstrate the importance of experimental evidence by describing research that has been particularly valuable in the field |
| pearson meiosis: Molecular Architecture and Dynamics of Meiotic Chromosomes Ricardo Benavente, Mónica Pradillo, Pedro A. San-Segundo, 2024-03-11 Meiosis is a special type of cell division that allows the generation of haploid gametes and is a key process for sexual reproduction of animals, plants and fungi. Haploidization requires that meiotic cells undergo a series of unique processes; namely, pairing, synapsis, recombination and segregation of homologous chromosomes. This involves profound meiosis-specific changes in the protein composition and architecture of homologous chromosomes as well as of the condensation and folding of chromatin that require a critical timing and regulation. Despite this enormous complexity, different organisms may achieve haploidization through common molecular mechanisms. A major goal of this article collection is to provide an overview of how meiotic chromosomes and their components are critically involved in the mechanisms of haploidization and how dynamic protein complexes yield important structural intermediates and temporal regulation to this process. We welcome submissions of original articles, mini-reviews and review articles dealing with the composition, architecture, function and regulation of meiotic chromosomes of animals, plants and fungi using microscopic, biochemical, molecular, genetic and/or ‘omic’ techniques. |
| pearson meiosis: Plant Cytogenetics, Third Edition Ram J. Singh, 2016-11-18 Cytogenetics plays an important role in understanding the chromosomal and genetic architecture of plant species. Plant Cytogenetics, Third Edition follows the tradition of its predecessors presenting theoretical and practical aspects of plant cytogenetics. Chapters describe correct handling of plant chromosomes, methods in plant cytogenetics, cell division, reproduction methods, chromosome nomenclature, karyotype analysis, chromosomal aberrations, genome analysis, transgenic crops, and cytogenetics in plant breeding. This new edition begins with a brief introduction on the historical aspect of cytogenetics and flows directly into handling of plant chromosomes by classical and modern cytological techniques, classical Mendelian Genetics, brief description of cell division, and chromosome identification by karyotype analysis. The comprehension of cytogenetics is incomplete without information on the role of aneuploidy in associating a gene on a particular chromosome, and the book covers these methodologies as a primary topic. Covering classical to modern cytogenetics, the book presents to the reader the crucial role of cytogenetics in improving crops. |
| pearson meiosis: Biocommunication of Archaea Guenther Witzany, 2017-09-27 Archaea represent a third domain of life with unique properties not found in the other domains. Archaea actively compete for environmental resources. They perceive themselves and can distinguish between ‘self’ and ‘non-self’. They process and evaluate available information and then modify their behaviour accordingly. They assess their surroundings, estimate how much energy they need for particular goals, and then realize the optimum variant. These highly diverse competences show us that this is possible owing to sign(aling)- mediated communication processes within archaeal cells (intra-organismic), between the same, related and different archaeal species (interorganismic), and between archaea and nonarchaeal organisms (transorganismic). This is crucial in coordinating growth and development, shape and dynamics. Such communication must function both on the local level and between widely separated colony parts. This allows archaea to coordinate appropriate response behaviors in a differentiated manner to their current developmental status and physiological influences. This book will orientate further investigations on how archaeal ecosphere inhabitants communicate with each other to coordinate their behavioral patterns and whats the role of viruses in this highly dynamic interactional networks. |

| pearson meiosis: Overcoming Students' Misconceptions in Science Mageswary Karpudewan, Ahmad Nurulazam Md Zain, A.L. Chandrasegaran, 2017-02-28 This book discusses the importance of identifying and addressing misconceptions for the successful teaching and learning of science across all levels of science education from elementary school to high school. It suggests teaching approaches based on research data to address students’ common misconceptions. Detailed descriptions of how these instructional approaches can be incorporated into teaching and learning science are also included. The science education literature extensively documents the findings of studies about students’ misconceptions or alternative conceptions about various science concepts. Furthermore, some of the studies involve systematic approaches to not only creating but also implementing instructional programs to reduce the incidence of these misconceptions among high school science students. These studies, however, are largely unavailable to classroom practitioners, partly because they are usually found in various science education journals that teachers have no time to refer to or are not readily available to them. In response, this book offers an essential and easily accessible guide. |
| pearson meiosis: Ovarian Aging: Pathophysiology and Recent Development of Maintaining Ovarian Reserve, volume III Antonio Simone Laganà, Akira Iwase , Osamu Hiraike, 2024-08-16 Age-related fertility decline is a striking phenomenon for women and there is an increasing tendency for later marriage and the postponement of childbearing in industrial countries. Many epidemiological observations also point out that almost one-tenth of reproductive-aged women require infertility treatment in these countries. Although the uterus is somewhat affected by ageing, the ageing ovary is considered a major but inevitable phenomenon. Consequently, preserving future fecundity is generally understood as preserving ovarian function; this is becoming a major concern for physicians specialized in reproductive medicine. Several chemicals have proved to improve or maintain the ovarian follicular pool, though the efficacy is still limited. |

| pearson meiosis: Reproduction and Development in Platyhelminthes T. J. Pandian, 2020-01-28 This book is a comprehensive elucidation on aspects of reproduction and development in platyhelminthes covering from acoelids to taeniids. With the unique presence of neoblasts, turbellarians serve as a model for studies on cancer and senescence. Of ~ 27,000 species, ~ 77% are parasites; they are harmful to man and his food basket from livestock and fish. The stress hormone, cortisol level is responsible for susceptibility and resistance of the host. In digeneans, the propagatory multiplication potency is retained by all the larval forms and in either direction in sporocyst. The higher clonal diversity, mixing and selection in Second Intermediate Host (SIH) may purge inbreeding depression suffered by the fluke on propagatory multiplication in First Intermediate Host (FIH). Of 12,012 digeneans, 88% may engage 33,014 potential SIH species. They have the choice to select one among the available/awaiting 3.5 host species. The motility of vertebrate host and euryxenic flexibility/scope for selection of SIH species has increased lineage diversification in digeneans. The life cycle of cestodes is divided into aquatic and terrestrial patterns. The former includes (i) oncosphere and (ii) coracidium types and the latter (iii) hexacanth-cysticercoid, (iv) hexacanth-tetrathyridium and (v) hexacanth-cysticercus types. The share for the oncosphere, coracidium and hexacanth types is 17.0, 29.5 and 46.5%, respectively. The staggering fecundity and adoption of the intermediate host in the herbivorous/insectivorous food chain have enriched Taenioidea as the most (2,264) speciose order. Sex specific genes Smed-dmd 1 and macbol have been identified, and neuropeptides and dipeptides are involved in sexualization. Trematodes are unable to parasitize elasmobranchs, as they cannot suck body fluid/blood containing a high level of urea. Relatively higher fecundity supplemented with propagatory multiplication, incorporation of SIH in 88% species, clonal selection in SIH, and euryxenic flexibility and the widest choice for selection of SIH have led to the highest lineage diversification to render digeneans as the most speciose order in Platyhelminthes. |
| pearson meiosis: The Tomato Crop J. Atherton, J. Rudich, 2012-12-06 The tomato is commercially important throughout the world both for the fresh fruit market and the processed food industries. It is grown in a wide range of climates in the field, under protection in plastic greenhouses and in heated glasshouses. Genetic, physiological and pathological investigations frequently adopt the tomato plant as a convenient subject. Hitherto, much of the information on tomatoes has been fragmented: tomatoes grown in the field and under protection have been considered separately and the more fundamental findings from research have often failed to reach those involved directly or indirectly in commercial crop production. Similarly, the research scientist is often unaware of the problems of commercial crop production and the possible relevance of his work to the crop. This book is an attempt to rectify that situation. By giving a thorough scientific review of all factors influencing tomato production systems, it is hoped that this book will prove useful to students, researchers and commercial producers alike. It gives the basis for the develop ment of improved cultivars, the formulation of strategies for managing pest, disease and disorder problems and the production of high yields of good quality fruit as well as suggesting important areas for scientific initiatives. The extensive bibliographies provide a comprehensive database for tomato researchers. Such a vast subject could not be covered with authority by anyone author. |

| pearson meiosis: Aneuploidy Vicki Dellarco, 2012-12-06 The Symposium on Aneuploidy: Etiology and Mechanisms was held at the Carnegie Institution of Washington Auditorium from March 25-29. 1985. This Symposium developed as a consequence of the concern of the Environmen tal Protection Agency with the support of the National Institute of Envi ronmental Health Sciences about human exposure to environmental agents that cause aneuploidy. The program was chosen to explore what is currently known about the underlying causes, the origins, and the extent of the prob lem of human aneuploidy, and whether exposure to environmental agents is assodated with an increased incidence of aneuploidy in humans. Basic research findings in the area of mitosis and meiosis were presented and related to possible mechanisms of how aneuploidy may be produced spontane ously and chemically. A survey of data regarding the chemical induction of aneuploidy in experimental organisms was presented. Outstanding scientists from different fields were invited to cover a broad perspective of aneu ploidy from the molecular aspects to the human situation. We hope that the publication of the proceedings will share the enthu siasm of the meeting and its scientific content. The topic of aneuploidy has received little attention and it is the purpose of this Volume to establish a scientific basis for assessing health risks posed by environ mental exposures to aneuploidy-inducing chemicals.

| pearson meiosis: Signaling-Mediated Control of Cell Division Swathi Arur, 2017-02-28 This volume covers the current knowledge base on the role of signaling and environmental pathways that control the normal development of germline stem cells, meiotic progression of oocytes, events of oocyte maturation and fertilization, and the birth of an embryo. Germ cells are uniquely poised to sustain life across generations through the fusion of oocyte and sperm. Because of the central importance of germ cells to life, much work has been dedicated to obtaining a clear understanding of the molecular and signaling events that control their formation and maintenance. Germ cells are set aside from somatic cells in the embryo and go through specialized meiotic cell cycles as the animal matures. These cell cycles are interspersed with long periods of arrest. In human females, meiosis I is initiated in the fetus. At birth, oocytes are arrested in meiosis I; after puberty, every month an oocyte initiates meiosis II – ovulation. Upon sperm availability these cells are fertilized, generate an embryo, and the cycle-of-life continues. During meiotic I progression and arrest, the fitness of oocytes and their progeny are likely influenced by environmental cues and signaling pathways. A lot of recent work has focused on understanding the mechanisms that regulate oocyte fitness and quality in humans and vertebrates. Much of our understanding on the events of meiosis I and germline stem cell populations comes from work in invertebrates, wherein the germline stem cells produce oocytes continuously through adult development. In both inverbrates and vertebrates nutritional and signaling pathways control the regulation of stem cells in such a manner so as to couple production of gametes with the nutritional availability. Additionally, mature oocytes arrest both in meiosis I and meiosis II, and signaling and nutritional pathways have been shown to regulate their formation, and maintenance, such that despite long periods of arrest, the oocyte quality is assured and errors in chromosome segregation and varied cytoplasmic events are minimal. |
