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.

What can be concluded from the graph and the description of the experiment?
A) fertilizer b is more expensive than fertilizer a
B) fertilizer a has a slower growth rate effect on the plants compared to fertilizer b
C) plants using fertilizer a were located further away from windows where sunlight was present
D) during a four week period, the plants with fertilizer b received more water than the plants with fertilizer a
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.
Is it possible for the Didinium and Paramecium to coexist on a petri dish? Select one:
A. Yes
B. No

I am a bit confusedarrow_forwardIn the pictures below, identify the arrowed reproductive structures of microscopic cyanobacteria based on the following descriptions: Akinetes are dormant structures larger than the vegetative cells, are rich in food reserves, and have thick walls. Most filamentous cyanobacteria develop akinetes in adverse conditions (e.g., winter, dry periods). When favorable conditions return, they germinate and produce new filaments. Hormogonia are short pieces of filaments consisting of 5–15 trichomes that fragment and develop into new filaments. Heterocytes (or heterocysts) are multicellular structures that have a thick and massive sheath, formed by members of the Nostocales. It is the location of the enzyme nitrogenase for nitrogen fixation, the conversion of nitrogen gas into ammonium and then amino acids. They may be intercalary or terminal in position and may germinate from either end or both the ends to give rise to new filaments. Non-filamentous cyanobacteria generally produce spores…arrow_forward
