Cell Division, Heredity, and Rcolution Practice Questions Cell Division An organism is heterozygous at two gene loci on different chromosomes. Explain how these alleles are transmitted by the process of mitosis to daughter cells. After mitosis the parent cells genome is dividedninto two daughter cells. In most eukaryotes, the nuclear envelope that separates the DNA from the cytoplasm disassembles. The chromosomes align themselves in a line spanning the cell. As the cell elongates, corresponding sister chromosomes are pulled toward opposite ends. A new nuclear envelope forms around the separated sister chromosomes. As mitosis completes, cytokinesis is well underway. Explain how these alleles are distributed by the process of†¦show more content†¦Organs begin to form in organogenesis. The embryo develops into a larval stage, the tadpole. Metamorphosis then turns the tadpole into a frog. Compare and contrast the formation of sperm and egg. With sperm, each cell goes through meiosis to produce four sperm cells. During oogenesis a oogonium cell undergoes mitosis to produce primary oocytes. It differs from sperm formation because it is a stop-start process. It also divides the cell unequally and one primary oogonium cell produces one active cell in contrast to sperm. Ecology Describe the process of ecological succession. It is the observed process of change in the species structure of an ecological community over time. Within any community some species may become less abundant over some time interval, or they may even vanish from the ecosystem altogether. Similarly, over some time interval, other species within the community may become more abundant, or new species may even invade into the community from adjacent ecosystems. This observed change over time in what is living in a particular ecosystem is ecological succession. Name five properties of populations and explain what they tell us about a population. Size Tells us the mass Density Tells us how many Dispersion Tells us how they are spread out Survivorship curves Tells us how many survive in a graph Age structure diagrams Tells us the age ranges The Cell CompareShow MoreRelatedHow Cultured Hippocampal Neurons And Proteins And Rna Transport763 Words   |  4 PagesWM, de Brouwer AP, Haas SA, Bienek M, Hu H, Vissers LE, van Bokhoven H, Kalscheuer V, Nadif Kasri N, Kleefstra T.
