ASU BIO 181 EXAM 1. Questions and answers, 100% Accurate. Graded A+ Comparing a single-celled eukaryotic organism with a multicellular organism such as yourself identify the major difference from the list below. A. Escape from predator B. Finding a mate C. Division of Labor D. Find it's own food E. Nucleus The paramecium swims by way of using a flagella. The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: A. Heart B. Kidney C. Liver D. Mouth E. Answer is not listed In your own multicellular body, cells with different functions have different DNA. A single-celled eukaryotic organism: A. Has a limited number of biomolecular machines. B. Must find food, shelter, a mate and reproduce C. Escape from predators D. None of the above E. Answers A,B,C A cell that is anchorage-dependent for growth will also exhibit contact inhibition. In your own multicellular body, different cells in your body have a division of labor between them. Compared to bacteria which of the cell types below are not responsible for finding food" A. Lymphocyte B. Macrophage C. Fibroblast D. None of the above E. Answers a, b, and c What limits the paramecium from acquiring more complex functions? A normal cell is anchorage-dependent for growth and mortal. In order to examine cells which are smaller than can be detected by the human senses what needs to be used? (pick the best answer). A. Patience B. Hypotheses C. Technology D. A cell trap E. None of the above In Cell Biology what can limit the progress of science? A. Lymphocyte B. Progress C. Eating D. Bacteria E. Technology A cancer cell will be anchorage-dependent for growth and immortal. A cell that is itself an organism must have a minimum of four needs presented in lecture. List these four things. Write a few sentences that explain what limits an individual cell from becoming more complex. What limits how big a cell can be? A. Color B. Wavelength C. The surface area to volume ratio D. Resolution E. Type of electron microscopy. TEM provides a thin, two-dimensional section of the object being studied. In an extant prokaryotic cell, the outer boundary of life is the capsule. The ancient earth did not contain much oxygen. Why is it important to know the limitations of technology? DNA in extant prokaryotic cells is circular. Loss of the cell wall is required for the endosymbiotic theory. The cytoskeleton gave rise to the nuclear envelope. The presumed first step in the transition of the primitive, proto-prokaryotic cell into the primitive, proto-eukaryotic cell was the loss of the cell wall. Group of answer choices List one limitation of the cell culture technique. It is presumed that the peroxisomes evolved in these primitive, proto-eukaryotes to remove oxygen, which was toxic to the primitive cells. A normal cell is ____________and _________________for growth. Motility improved the fitness of these early cells because: It allowed them to make a nuclear envelope. It caused them to acquire ribosomes. It allowed them to move away from predators and towards food. Two of the above. None of the above. Loss of the cell wall was required for the endomembrane system theory. Group of answer choices
