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...

How do you calculate the magnification of a drawing/image? - correct answer Magnification=Image size(with ruler) / Actual size(according to scale bar) How do you calculate the actual size of a magnified specimen? - correct answer Actual size=Image size(with ruler) / magnification By which process do potassium ions move through potassium channels in axons? - correct answer Facilitated diffusion -at rest, the Na-K+ pump expels Na+ ions out of cell, while K+ are put within -when the n...

Write a few sentences that explain what limits an individual cell from becoming more complex. - Correct answer-Bimolecular machinery and division of labor The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: - Correct answer-Kidney In cell Biology what can limit the progress of science? - Correct answer-Technology True or False: In you own multicellular body, cells with different functions have different DNA - Corre...
