30 EVOLUTIONPeppered Moth Background: Naturalselection is the reproductive success of organisms that are best suited for an environment. It is the driving force of evolution. Natural selection occurs within populations, which are interbreeding groups of individuals of the same species. Genetic variation is one factor that influences natural selection. Ge-netic variation occurs when a population has multiple versions of a trait. For exam-ple, some organisms in a population of moths are dark colored, while some are light colored. Natural selection over time results in adaptations, where certain traits are favored due to their influence on survival. Adaptations over many generations can lead to evolution. Peppered moths have lived in the forests around Manchester, England for hundreds of years. There are two genetic variations for color in pep-pered moths- the moths can be dark with light spots OR light with dark spots. Cell Cycle:are the processes, stages and duration for which cells replicate and grow. Match the stages with their description. Before the 1800s (figure 14.11a), the trees were light colored and the light colored moths were well camouflaged. After the 1800s, when England went through the Industrial Revolution, the pollution from factories made the trees darken (figure 14.11b). Now, the trees were dark colored and the dark colored moths were well camouflaged. Various birds eat both kinds of moths IF they are able to be seen. Data: The table below displays the Number of peppered moths of each color found over a ten year period. Graph the data below to show how the peppered moth popu-lations changed in the 1800s. You should make a line graph with two lines. Years should be on the x axis and number of moths on the y axis. Assume year one was the start of the industrial revolution.Peppered Moth PopulationsYearLight Colored PopulationDark Colored Population1537112248419833922104246281522535761934127147503884594953638103867311 Mitosis & Meiosis_____ Interphase a. Chromosomes are pulled to opposite poles _____ Prophase b. Nuclear membrane forms around chromosomes at each pole _____ Metaphase c. Chromosomes duplicate and spindle fibers occur and centrioles move to opposite poles _____ Anaphase d. Cytoplasm and other organelles are separated (not con sidered a part of mitosis) _____ Telophase e. Growth phase for cell. Majority of cells life is in this cycle. (not considered a part of mitosis) _____ Cytokinesis f. Duplicated chromosomes are lined up in the middle of the cell Interphase and Mitosis:please use 3 homologous chromosomes and draw the phases of the cell cycle below: The end product of Mitosis is the formation of two new identical daughter cells for the body (also known as somatic cells). Each cell has the same number of chromo-somes and is diploid (2n).
