Summary Introduction
To review:
The evidence that cells of the dorsal lip of the blastopore act as an inducer cell.
Introduction:
Blastopore is the opening on the embryo through which the movement of cells takes place to form ectoderm, endoderm, and mesoderm. The cells of blastopore later develop into the mouth and anus.

In the early 1930s, G. F. Gause carried out a series of experiments using two species of ciliated protists (Paramecium), which are single-celled eukaryotic protozoans. The protists were cultured together and separately, with the bacteria being the single food source. The results are shown in the figure below.
(a) Based on figure, identify and explain the interaction that is taking place between P. caudatum and P. aurelia.
(b) Clam shrimp, a natural predator to P. caudatum, is introduced to the culture containing both P. caudatum and P. aurelia after 24 days. Predict the impact that the clam shrimp will have on the culture and the populations. Justify your prediction.
How is the Trypanosoma’s ability to produce an array of cell surface proteins advantageous to its survival? Explain
