ASU BIO 181 EXAM 1 QUESTIONS AND ANSWERS 100% VERIFIED In Cell Biology what can limit the progress of science? - answerTechnology- no method is perfect Which of the cell types below are not responsible for finding food? - answer1. Macrophage - initiates immune system 2. Lymphocyte - helps fight cancer and infection 3. Fibroblast - forms connective tissue T/F Cells in your body with different functions have the different DNA. - answerFALSE - every cell in your body contains the same DNA, just different parts are activated What major difference separates us (humans and multi-celled organisms) with single celled eukaryotes? - answerMulticellular organisms utilize "Division of Labor"- the idea that organelles specialize certain tasks so that the unit of the whole can thrive. Define anchorage dependence. - answerIn order to grow and divide, a cell must be attached to a solid surface. Define contact inhibition. - answerWhen cells come into contact with a neighbor, they stop dividing and the layer of cells remain one-cell thick. T/F A cell that is anchorage-dependent for growth will also exhibit contact inhibition. - answerTRUE What limits the paramecium from acquiring more complex functions? - answerThe number of bimolecular machines it can fit within its "space". The existing bio-machines must repurpose themselves completely to complete a task, which means it can't fully 'automate' itself. What organ is the contractile vacuole assumed precursor to? - answerKidney - both systems expel excess; CV with extra water and the kidney expelling waste via urine (water + ick) T/F
