Questions What does the term "Acid Fa" mean? Are acid-Fast organisms Gram-positive or Gram- 2 Do your results indicate that endospores are acid-fast? Explain. 3 Why is it best to use "old" cultures for this staining procedure? 4 When you stain your Mycobacterium smegmatis, some of the cells are red and others are blue.

List the result obtained (acid-fast/non-acid-fast) from the preparations of each of the assigned organism. Normally when viewing a stained preparation. One bases decisions on the predominant form in the field. Why is this not the procedure when viewing an acid-fast preparation? List 2 condition(s) when an acid-fast organism may appear non-acid-fast. Why do Mycobacterium organisms tend to occur in groups or clumps on a preparation? Considering the nature of the cell wall of Mycobaterium organisms, how might...

Answer questions 1-5 Compare and contrast the underlying causes of time delays in predator-prey interactions. What is the Lotka-Volterra Model? What is the relationship that exists between predators and prey? How is this model affected by time? Compare functional and numerical response. What are the different types of functional responses related to prey consumed to prey density? Are predators affected by these changes in density? Is there a pattern? Compare and contrast lethal and nonlethal effects of predation. Give examples...

LAB REPORT 2- Selected questions from Exercise 3-7 (Acid-fast stain) Note: This is turned in after you have viewed your acid fast stain slides. Bacteria for this exercise are: Mycobacterium smegmatis (or M. phlei) and S. aureus. Q1. Acid fast bacteria are have some significant differences as compared to non-acid fast bacteria. What are the major chemical (structural) differences among these different bacteria that might explain the acid-fast stain? Hint: This structural difference also affects the way the bacteria grow...

1. Compare and contrast the two root partnerships described in this chapter: arbuscular mycorrhizae and rhizobia. Be sure to address the benefits received by the organisms involved in each symbiosis, similarities and differences between the fungal & bacterial strategies 2. Holoparasitic plants have lost many of the morphological and genetic traits necessary for an autotrophic lifestyle. From an evolutionary point of view, how do you think this happened (hint: apply Darwin’s 4 principles of natural selection)
