Must be psychological trait must be a physical trait can not be a heritable trait must be a physiological trait must be a heritable trait must be a heritable trait what is the availability of one or more organisms in genetic resistance a population to tolerate a chemical designed to kill it such as when bacteria tolerate antibiotics? genetic resistance genetic adaptation genetic mutation genetic strength genetic tolerance biological evolution by natural selection is when Mutate; are selected; evolve genes___, Individuals ,And populations___. are selected; mutate; evolve evolve; are selected; mutate mutate; evolve; are selected Mutate; are selected; evolve evolve; mutate; are selected What adaptations have allowed humans 2 increase opposable thumbs our chances of survival and reproduction through gripping and use of tools? walking upright with 2 legs complex brain opposable thumbs 5 digits on each hand physical strength what human adaptation may enable us to live more our complex brain sustainably by understanding and copying the ways in which Nature has sustained itself for billions of years despite major changes in environmental conditions? our biological Fitness is superior to other animals our physical strength our genes can change over time our complex brain our ability to use tools why do species such as humans take a much longer species such as humans are limited by reproductive capacity time (Thousands of millions of years) to adapt through natural selection than species such as bacteria and insects? species such as humans are limited geographically species such as humans are much larger in size species such as humans are limited by biological Fitness species such as humans are limited by reproductive capacity species such as humans are limited by natural selection from a scientific point of view which of the Fitness as a matter of reproductive success following is true? Evolution leads to survival of the strongest Evolution leads to survival of the most valuable Evolution follows a plan of nature organisms develop traits because they need them Fitness as a matter of reproductive success fossils tell us about the long history of life on Earth 1% and so far are fossil record probably represents_____ of all species that have ever lived. 20% 1% 50% 5% 75% the process whereby Earth's life changes over time evolution through changes in gene of populations of organisms in succeeding Generations is called____. Natural selection Mutation emmigration genetic drift evolution who was responsible for providing a convincing Charles Darwin and Alfred Russet Wallace explanation of how organisms change over time and are descended from a single common ancestor through the mechanism of natural selection? Charles Darwin and Alfred Russet Wallace Charles Darwin Charles Darwin and Edward O. Wilson Alfred Russel Wallace Edward O. Wilson the process in which individuals with certain traits natural selection are more likely to survive and reproduce under a particular set of environmental conditions than those without the trait is called__. Genetic drift Adaptability scientific theory Mutation natural selection The Variety in genetic makeup of individuals in a genetic variability population is known as____. genetic variability Heritability gene flow genetic differences genetic drift Changes in the DNA molecules of a gene in any heritable traits cell that can be inherited by offspring are called Mutagens Adaptations selected traits heritable traits APES chapter 4 test scientists are now able to produce desirable traits mutation in some organisms by adding deleting or changing segments of DNA this process is known as____. genetic modification genetic drift Speciation genetic engineering mutation the Earth has sustained life for______ years 3.5 billion 1.5 billion 3.5 million 3.5 billion 1.5 million 1.5 trillion the fact that tectonic plates drift influences changing the earth's climate evolution by___. changing magnetic fields and disrupt migration patterns decreasing soil nutrient richness changing the earth's climate increasing levels of carbon dioxide changing the spin of the Earth mass extinctions with 25 to 95% of species going 3-5 extinct have occurred how many times in history of the Earth? -8 3-5 1 or 2 the Earth's biodiversity is determined by the speciation and Extinction balance between _. speciation in genetic engineering reproductive isolation and Extinction geographic isolation and reproductive isolation mass extinction and background Extinction speciation and Extinction under certain circumstances natural selection can Speciation lead to an entirely new species a process called _. Mutation genetic isolation Diversification Speciation genetic drift geographic isolation may result from____. mountain ranges Extinction Reproductive isolation Artificial selection Speciation mountain ranges when a species becomes extinct over a large local extinction region but not worldwide it is called___. Global Extinction background Extinction partial Extinction local extinction mass extinction which of the following is true? the higher the species richness the more sustainability The higher the species richness the lower the sustainability the higher the species richness the lower the productivity the lower the species richness the more productivity the lower the species richness the more sustainability the higher the species richness the more sustainability what term describes the number of different species richness species in a given area? species richness species evenness species niche Habitat speciation a measure of the relative abundance of species evenness comparative number of individuals of each species present is called Species abundance species counts species diversity species evenness species richness According to some scientists the more diverse an more productive ecosystem is the it will be less abundant less even more productive less productive more even Which of the following would be the least likely prolonged rainy periods cause for the decline of amphibians? prolonged rainy periods Pollution Parasites increase in UV radiation habitat destruction the role a species plays in its ecosystem is its__. ecological niche Ecological job Function ecological niche Habitat geographical location the loss of a___ can lead to population crashes and keystone species extinctions of other species in a community that depends on them for certain ecosystem services. native species indicator species Foundation species keystone species specialist species before conservation efforts facilitated their Hunters comeback the American alligator population was nearly completely wiped out primarily because of___. Diseases Pollution Parasites Hunters land Developers which of the following does not describe an the place where the species lives element of an ecological niche? how much water the species needs How much sunlight does species needs the place where the species lives how much space does species needs temperatures the species can tolerate a species with a broad niche is considered a generalist species specialist species generalist species native species endemic species endangered species which of the following would not be considered a Pandas generalist species Raccoons Humans Cockroaches Pandas White tail deer which of the following is true of specialist species they can tolerate a narrow range of climatic conditions they are less prone to Extinction they can live in many different places they can eat a wide variety of foods they can tolerate a narrow range of climatic conditions they can tolerate a wide range of environmental conditions today the____ is among the most threatened of all Giant panda species in the world, with only 1600 to 3000 individuals left in the wild Giant panda American alligator killer whale American bullfrog koala which of the following is another name for a non- invasive native species invasive Indicator Native Keystone Foundation non-native species can spread rapidly if they find a Predators new location with favorable conditions often because they do not face the same that they face in their native niches Pollinators Temperatures precipitation ranges soil nutrients Predators Species that provide early warnings of damage to a Indicator species community or an ecosystem are called__.
