Bio 1108 Final Exam (Grade A) The term "n" refers to the size of a population, that is the number of individuals in a population. In general, in a sample of n individuals, the frequency of an allele is If a population is not in Hardy Weinberg, we can conclude that: The goldenrod gall fly lays its eggs on the terminal buds of goldenrod plants. Larvae chew through the buds and into the stems, where their saliva induces the plant to generate a gall (an outgrowth of tissue). This gall then provides food and shelter for the developing larva. The larvae are prey of both parasitoid wasps and birds. Wasps selectively prey on larvae inside the smallest galls while birds selectively prey on larvae inside the largest galls. Goldenrod gall flies are therefore subject to.. You find that a wild population of antelope is not in Hardy-Weinberg Equilibrium. From this information alone, can you determine the mechanism of evolution operating on the population? A population with a novel adaptation has evolved that adaptation A polytomy is a graphical depiction of what type of relationship between groups? Phylogenetic trees are: Which phylogenetic group includes all descendants of a common ancestor and only the descendants of that ancestor? When comparing trees with various hypotheses of evolutionary relationships between a group of animals, the tree with ______ would be the strongest candidate. Three populations of crickets look very similar, but the males have courtship songs that sound different. What function would this difference in song likely serve if the populations came in contact? The peppered moth provides a well-known example of natural selection. The light-colored form of the moth was predominant in England before the industrial revolution. In the mid-nineteenth century, a dark-colored form appeared. The difference is produced by a dominant allele of one gene. By about 1900, approximately 90% of the moths around industrial areas were dark colored, whereas light-colored moths were still abundant elsewhere. Apparently, birds could readily find the light moths against the soot-darkened background in industrial areas and therefore were eating more light moths. Recently, use of cleaner fuels has greatly reduced soot in the landscape, and the dark-colored moths have been disappearing. Should the two forms of moths be considered separate species? How does the level of genetic variation in humans typically compare to other species Where did Homo sapiens evolve? Cultural traits are transmitted horizontally and vertically through learning. Which example shows horizontal transmission? Why do we think that male Neanderthals mated with non-African ancestral Homo sapiens? What is the definition of neoteny? Why do mitochondria and chloroplasts have relatively small genomes? How old are the earliest fossils of eukaryotes as defined by the super-kingdoms? What causes amoeboid feeding cells of cellular slime molds to aggregate into a large multicellular 'slug'? Why is photosynthesis widely but discontinuously distributed throughout the eukaryotic tree? Which of the following enabled eukaryotes to evolve complex life cycles and programs of multicellular development? Some slime molds make structures called plasmodia which: Chloroplasts have outer and an inner membranes that separate the stroma and thylakoids from the cytoplasm. What is believed to be the origin of the outer membrane of the chloroplast? A marine biologist discovers a new species of green algae, which under the microscope appears to be multinuclear. Which of the following is likely true of this algae? In simple multicellularity: The majority of prokaryote DNA is arranged in For the “light” reaction to occur, an electron donor (____) and an ultimate acceptor (______) are needed Which molecule is oxidized in the photosynthetic reaction? Which molecule is reduce is PSN? In terms of evolution of photosynthesis, which happened first? What is the most abundant protein on Earth? What is the initial carbon input in the Calvin cycle? Root hairs on a root develop.. The veins of leaves are... If the two guard cells of a stoma decrease their concentration of potassium (K+) ions, what will happen to the corresponding pore? If water molecules (H2O) suddenly stopped forming hydrogen bonds with one another, how would water transport in vascular plants change (if at all)? You are watching a group of seals and are observing their behavior on a beach. You notice separate groups of females and observe that each group is affiliated with just a single male. What data support the hypothesis that sexual selection played a role in the evolution of these behaviors? According to Niko Tinbergen, which of the following defines―and helps researchers understand―an animal’s behavior? A hummingbird is visually attracted to the red, tubular flowers of a trumpet vine. It drinks nectar from the flower and, in doing so, inadvertently transfers pollen from one flower to the next. In this form of communication, who is the sender, who is the receiver, and what information is being transferred? ____ are close interactions between species that have evolved over long periods of time. When these interactions enhance the reproduction and population growth of both species, they are called _____ A species' ___________ niche will be smaller than its _______ niche due to interactions with other organisms in the community.
