In a chaste trial on race betwixt stamp for a common influence commencement, the Russian microbiologist G. F. Gause grew populations of different stamp of ciliated protozoans partially and conjointly in an artificial cultivation medium. He counted the reckon of cells of each stamp and plotted the entirety book of each population. The organisms were Paramecium caudatum and its delay not-absolute, Paramecium aurelia. He plotted the aggregate book of cells rather than the entirety reckon in each population owing P. caudatum is plenteous comprehensiver than P. aurelia (this magnitude dissimilarity undisputed him to distinguish betwixt them in a adulterated cultivation). The graphs in this box semblance the experimental results. As we mentioned prior in the quotation, this was one of the first trialal demonstrations of the energy of competitive disqualification. After studying these graphs, counter-argument the forthcoming questions.
1. How do you discover these graphs? What is semblancen in the top and depth panels?
2. How did the entirety book of the two stamp collate following 14 days of different enlargement?
3. If P. caudatum is roughly twice as comprehensive as P. aurelia, how did the entirety reckon of cells collate following 14 days of different enlargement?
4. How did the entirety book of the two stamp collate following 24 days of enlargement in a adulterated population?
5. Which of the two stamp is the more successful competitor in this trial?
6. Does the comprehensiver stamp frequently win in race for food? Why not?
