cause and effect essays about drinking and drivingCause and effect essays about drinking and driving -adaptive radiation: The diversification, over evolutionary time, of a species or group of species into several different species or subspecies that are typically adapted to different ecological niches (for example, Darwin's finches).Brodie, Edmund D., Jr.: A biologist recognized internationally for his work on the evolution of mechanisms in amphibians that allow them to avoid predators.Asexual reproduction occurs without fertilization or genetic recombination, and may occur by budding, by division of a single cell, or by the breakup of a whole organism into two or more new individuals.The diameter of the aperture determines the intensity of light admitted. archeology: The study of human history and prehistory through the excavation of sites and the analysis of physical remains, such as graves, tools, pottery, and other artifacts.Bruner, Jerome: A psychologist and professor at Harvard and Oxford Universities, and a prolific author whose book, The Process of Education, encouraged curriculum innovation based on theories of cognitive development.The forms of most domesticated and agricultural species have been produced by artificial selection; it is also an important experimental technique for studying evolution.biogeography: The study of patterns of geographical distribution of plants and animals across Earth, and the changes in those distributions over time.bryozoan: A tiny marine invertebrate that forms a crust-like colony; colonies of bryozoans may look like scaly sheets on seaweed.antibiotic resistance: A heritable trait in microorganisms that enables them to survive in the presence of an antibiotic.The term can also be applied to larger groups of organisms, as in "the adaptive radiation of mammals." adaptive strategies: A mode of coping with competition or environmental conditions on an evolutionary time scale.A recent book, The Meme Machine, offers an introduction to the subject of memes. brachiopod: Commonly known as "lamp shells," these marine invertebrates resemble bivalve mollusks because of their hinged shells.carbon isotope ratio: A measure of the proportion of the carbon-14 isotope to the carbon-12 isotope.asteroid: A small rocky or metallic body orbitting the Sun.Burney, David: A biologist whose research has focused on endangered species, paleoenvironmental studies, and causes of extinction in North America, Africa, Madagascar, Hawaii, and the West Indies.These mechanisms include toxins carried in skin secretions, coloration, and behavior.Carroll, Sean: Developmental geneticist with the Howard Hughes Medical Institute and professor at the University of Wisconsin-Madison.bacteria: Tiny, single-celled, prokaryotic organisms that can survive in a wide variety of environments.Australopithecus afarensis: An early australopithecine species that was bipedal; known fossils date between 3.6 and 2.9 mya (for example, Lucy).bivalve: A mollusk that has a two-part hinged shell.Coauthor, with Jennifer Grenier and Scott Weatherbee, of From DNA to Diversity: Molecular Genetics and the Evolution of Animal Design.cause and effect essays about drinking and drivingBlackmore, Susan: A psychologist interested in memes and the theory of memetics, evolutionary theory, consciousness, the effects of meditation, and why people believe in the paranormal.In a diploid cell there are usually two alleles of any one gene (one from each parent).amphibians: The class of vertebrates that contains the frogs, toads, newts, and salamanders.Mendelian inheritance is an atomistic theory because in it, inheritance is controlled by distinct genes.amino acid sequence: A series of amino acids, the building blocks of proteins, usually coded for by DNA.Within a population there may be many different alleles of a gene; each has a unique nucleotide sequence.Much of his work concentrates on the coevolutionary arms race between newts that posess tetrodotoxin, one of the most potent known toxins, and the resistant garter snakes who prey on them.biodiversity (or biological diversity): A measure of the variety of life, biodiversity is often described on three levels.Peaks on the landscape correspond to genotypic frequencies at which the average fitness is high, valleys to genotypic frequencies at which the average fitness is low. adaptive logic: A behavior has adaptive logic if it tends to increase the number of offspring that an individual contributes to the next and following generations.Ecosystem diversity describes the variety of habitats present; species diversity is a measure of the number of species and the number of individuals of each species present; genetic diversity refers to the total amount of genetic variability present.About 20,000 have been observed, ranging in size from several hundred kilometers across down to dust particles.acquired trait: A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation (for example, the large muscles of a weightlifter).biological species concept: The concept of species, according to which a species is a set of organisms that can interbreed among each other.allometry: The relation between the size of an organism and the size of any of its parts.australopithecine: A group of bipedal hominid species belonging to the genus Australopithecus that lived between 4.2 and 1.4 mya.Some cause serious infectious diseases in humans, other animals, and plants.Carson, Rachel: A scientist and writer fascinated with the workings of nature.For example, an allometric relation exists between brain size and body size, such that (in this case) animals with bigger bodies tend to have bigger brains.amniotes: The group of reptiles, birds, and mammals.anatomy: (1) The structure of an organism or one of its parts. ancestral homology: Homology that evolved before the common ancestor of a set of species, and which is present in other species outside that set of species. anthropoid: A member of the group of primates made up of monkeys, apes, and humans. cause and effect essays about drinking and driving autosome: Any chromosome other than a sex chromosome.They have moist scaleless skin which is used to supplement the lungs in gas exchange.algae: An umbrella term for various simple organisms that contain chlorophyll (and can therefore carry out photosynthesis) and live in aquatic habitats and in moist situations on land. Algae range from macroscopic seaweeds such as giant kelp, which frequently exceeds 30 m in length, to microscopic filamentous and single-celled forms such as Spirogyra and Chlorella. For example, if a gene determines the seed color of peas, one allele of that gene may produce green seeds and another allele produce yellow seeds.It cannot be used to determine the age of Earth, for example.The eggs are soft and vulnerable to drying, therefore reproduction commonly occurs in water.Her best-known publication, Silent Spring, was written over the years 1958 to 1962.Then, even if circumstances change such that it no longer provides any survival or reproductive advantage, the behavior will still tend to be exhibited -- unless it becomes positively disadvantageous in the new environment.In artificial selection, breeders select the most desirable variants in a plant or animal population and selectively breed them with other desirable individuals.The amnion surrounds the embryo with a watery substance, and is probably an adaptation for breeding on land.Living material contains carbon-14 and carbon-12 in the same proportions as exists in the atmosphere.analogous structures: Structures in different species that look alike or perform similar functions (e.g., the wings of butterflies and the wings of birds) that have evolved convergently but do not develop from similar groups of embryological tissues, and that have not evolved from similar structures known to be shared by common ancestors. Note: The recent discovery of deep genetic homologies has brought new interest, new information, and discussion to the classical concepts of analogous and homologous structures.The pupil of a human eye is a self-adjusting aperture. archetype: The original form or body plan from which a group of organisms develops.Carroll's research has centered on those genes that create the "molecular blueprint" for body pattern and play major roles in the origin of new features.Because most carbon-14 will have decayed after 50,000 years, the carbon isotope ratio is mainly useful for dating fossils and artifacts younger than this.biogenetic law: Name given by Haeckel to recapitulation.base: The DNA molecule is a chain of nucleotide units; each unit consists of a backbone made of a sugar and a phosphate group, with a nitrogenous base attached.From the large-scale changes that distinguish major animal groups to the finely detailed color patterns on butterfly wings, Dr.Batesian mimicry: A kind of mimicry in which one non-poisonous species (the Batesian mimic) mimics another poisonous species.belemnite: An extinct marine invertebrate that was related to squid, octopi, and chambered nautiluses.The book looks at the effects of insecticides and pesticides on songbird populations throughout the United States. cause and effect essays about drinking and driving These all develop through an embryo that is enclosed within a membrane called an amnion.atomistic: (as applied to theory of inheritance) Inheritance in which the entities controlling heredity are relatively distinct, permanent, and capable of independent action.agnostic: A person who believes that the existence of a god or creator and the nature of the universe is unknowable.biometrics: The quantitative study of characters of organisms.artifact: An object made by humans that has been preserved and can be studied to learn about a particular time period.Bivalves include clams, oysters, scallops, mussels, and other shellfish.adaptation: Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment.If such a behavior is even partly genetically determined, it will tend to become widespread in the population.assortative mating: The tendency of like to mate with like.bioengineered food: Food that has been produced through genetic modification using techniques of genetic engineering.aperture: Of a camera, the adjustable opening through which light passes to reach the film.adaptive landscape: A graph of the average fitness of a population in relation to the frequencies of genotypes in it.Also used to describe the process of genetic change within a population, as influenced by natural selection.Amphibian larvae are aquatic, and have gills for respiration; they undergo metamorphosis to the adult form.Mating can be assortative for a certain genotype (e.g., individuals with genotype AA tend to mate with other individuals of genotype AA) or phenotype (e.g., tall individuals mate with other tall individuals).The publication helped set off a wave of environmental legislation and galvanized the emerging ecological movement. E.: An early experimental geneticist, his 1901 paper was the first on Mendelism in America.antibiotics: Substances that destroy or inhibit the growth of microorganisms, particularly disease-causing bacteria.asexual reproduction: A type of reproduction involving only one parent that ususally produces genetically identical offspring.Exceptions are those coded for by the RNA of certain viruses, such as HIV.We know from the fossil record that belemnites were common in the Jurassic period and had bullet-shaped internal skeletons. cause and effect essays about drinking and driving Asexual reproduction occurs without fertilization or genetic recombination, and may occur by budding, by division of a single cell, or by the breakup of a whole organism into two or more new individuals. cause and effect essays about drinking and driving
