Question
Chapter 27, Problem 13PIAT
Summary Introduction
To review:
The graph and case study provided in the question.
Given:
An U-shaped trap was placed between the Physarum and its food. Out of 24, 23 slime molds reached the food in the presence of plain agar. When the agar was coated with the extracellular slime, only 8 were able to locate the food. The graph for the same is provided below:
Introduction:
The P value refers to the level of the marginal significance in a statistical hypothesis test and it shows the probability of the occurrence of the provided event. Spatial memory is the memory part responsible for recording information about one’s environment and utilizing them to return to rewarding locations (home and food sites) in the brain.

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.
Many types of movement are employed by bacteria discussed in this chapter. Review them and propose mechanisms by which energy (ATP or proton gradients) might drive the locomotion.
Describe the process of host: bacteria recognition, attachment and infection for Rhizobium and legumes. What does the Rhizobium gain from association with the plant? What does the plant gain?
