Biology 5th Edition Brooker Test Bank Chapter 1 An Introduction to Biology Plant photosynthesis and the consumption of plants by animals are both examples of what unifying principle of life? All living organisms use energy. All living organisms maintain organization. All living organisms have evolved over the course of many generations. All living organisms maintain some level of homeostasis. All living organisms are composed of similar structures. A plant will begin floweri ng in response to changes in length of daylight, temperature, and light quality. This is an example of which unifying principle of life? Plants conduct photosynthesis. Living organisms maintain homeostasis. Living organisms interact with their environment. Living organisms grow and develop. Populations of organisms evolve from one generation to the next. Whether the external temperature is hot or cold, birds maintain an internal body temperature of approximately 40°C. This is an example of. metabolism. cellular respiration. growth and development. homeostasis. proteomics. Proteins are largely responsible for the traits of living organisms, while provides the blueprint for the organization, development, and function of living things. DNA protein carbohydrate lipid metabolite Which level of organization includes all of the others in the list? cell tissue organ organism population Which level of organization is common to all life forms? cell tissue organ organelle colony When cells in an organism associate with each other, they form atoms. molecules. macromolecules. tissues. populations. A community of organisms interacting with their physical environment is a(n) population. organism. biosphere. ecosystem. macromolecular community. Which is the smallest of all levels of organization? atom cell organ organism population Molecules are made up of atoms. cells. organs. organisms. populations. Boa constrictors on an island are an example of a(n) cell. organ. organism. population. ecosystem. A flower on a plant represents which level of organization? atom cell organ organism population The phenomenon through which populations of organisms change over several generations is termed homeostasis. growth and development. reproduction. biological evolution. organization. Changes in _ represent the predominant cause for biological evolution. homeostasis growth and development reproduction genetic makeup energy A variety of finch species within the Hawaiian Islands have acquired different types of beaks needed for utilizing specific food resources. What is the likely process by which these different species of finches came about? vertical descent with mutation horizontal gene transfer an accumulation of harmful genetic mutations What feature of genetic mutations can eventually lead to the evolution of new species? Mutations always produce harmful effects. Mutations never affect protein structure or function. Muta tions are not a mechanism through which biological evolution occurs. Mutations always produce beneficial effects. Mutations produce changes in the DNA sequence of a gene. New species evolve from preexisting species by the accumulation of metabolic events. genetic mutations. proteomes. reproductive events. developmental events. How does evolutionary change occur? Through the modification of characteristics in a preexisting population. It may involve vertical descent with mutation. It may involve horizontal gene transfer. All of these choices are correct. None of these choices are correct. In the process of biological evolution, new species may evolve through exchange of genes from one species to another. This process is called proteome transfer. horizontal gene transfer. vertical evolution. vertical descent with mutation. genomic sciences. The grouping or classification of species is termed genus. kingdom. taxonomy. When grouping organisms, which classification is most general for a particular type of organism? Kingdom Phylum Order Family Species All organisms in the Kingdom can perform photosynthesis. Animalia Protista Fungi Plantae Bacteria Our species is called Homo sapiens . The first word refers to which taxonomical grouping? Kingdom Phylum Order Genus Species
