Understanding Pathophysiology 7th Edition Test Bank Chapter 1. Cellular Biology MULTIPLE CHOICE 1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which of the following would also be observed by the student? a. A single circular chromosome b. A nucleus c. Free-floating nuclear material d. No organelles ANS: B The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its nucleus; thus,...

The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: - Correct answer-kidney A cell that is anchorage-dependent for growth will also exhibit contact inhibition. - Correct answer-true In your own multicellular body, cells with different functions have different DNA. - Correct answer-false The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. - Correct answer-true The paramec...
