SECTION II. SHORT PARAGRAPH QUESTIONS (25m) Answer each of the following four questions in full sentences. Do not use point form. (9m) The great majority of land plants establish mycorrhizal associations with fungi, in which there is a two-way exchange of nutrients between the plant and the mycorrhizal fungus. Host plants provide mycorrhizal fungi with sugars, while mycorrhizal fungi provide host plants with soil phosphorus. a. Design an experiment to test whether Douglas-fir seedlings grow more quickly in soil containing mycorrhizal fungal spores. Make sure that you state your null and alternate hypotheses, list your dependent and independent variables, describe your experimental setup (including control and experimental treatments), list your controlled variables (explaining how each will be controlled and why), and provide replication. b. Assuming that the results of the experiment support your alternate hypothesis, draw a graph to predict what the resulting data would look like. Donât forget to label your axes!

Need help developing a hypothesis and experiment based on a relationship to oxygen to growth lab (basic micro lab using thioglycollate, tsa agar plate and anaerobe boxes/gas packs as media and four cultures including Pseudomonas fluorescens, clostridium butyricum, Staphylococcus aureus, and enterococcus faecalis) determining which are obligate aerobs, obligate anerobes, facultative anaerobes, and aerotolerant. I need to design an experiment with hypothesis, controlled variable, independent variable, and dependent variable.
