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...
