BIO 181 Exam 1 Module 1-6 ASU questions with complete solutions

What limits the paramecium from acquiring more complex functions? correct answer: number of Bio molecular machines T/F? The paramecium swims by way of using a flagella. correct answer: False The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: correct answer: Kidney T/F? A cancer cell will be anchorage-dependent for growth and immortal. correct answer: False Comparing a single-celled eukaryotic organism with a multicellular organism such as yourself identify the major difference correct answer: Division of labor Traits of a A single-celled eukaryotic organism correct answer: Limited number of biomolecular machines, must find food, shelter, and a mate to reproduce. Must escape from predators. T/F?In your own multicellular body, cells with different functions have different DNA. correct answer: False In order to examine cells which are smaller than can be detected by the human senses what needs to be used? correct answer: Technology Compared to bacteria which of the cell types below are not responsible for finding food" correct answer: Lymphocyte, macrophage, fibroblast In Cell Biology what can limit the progress of science? correct answer: Technology T/F?The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. correct answer: True A cell that is itself an organism must have a minimum of four needs presented in lecture. List these four things. correct answer: 1. Chemical Complexity 2. Growth and reproduction 3. Ability to refashion substances from the environment 4. Ability to determine what can move into and out of the organism explain what limits an individual cell from becoming more complex correct answer: The individual cell is responsible for reproduction, growth, finding mates, gathering food, etc. The increased responsibilities of the cell force it to focus on just one thing at a time. In short, the single cell must do all of the labor by itself. Another caveat to an individual cell is when the cell changes it's function it also changes its engineering. In comparison, a multi-cellular organism is able to redistribute the work load and work as a unit with the many cells in the body. Naturally, the multi-cellular organism is able to accomplish more things by having fixed cells focused on different tasks to accomplish more at a faster rate. These cells experience differential gene expression wh
