A student mаkes the fоllоwing clаim: "Micrоbiаl diversity decreases when environmental salt concentration increases." The student grows the same microbial community under four different salt concentrations and records the number of different microbial species detected after the experiment. Salt Concentration (%) Number of Species Detected 1 24 3 19 6 12 9 5 Answer the following: A. Describe the overall relationship between salt concentration and microbial diversity shown in the data.(1 point) B. Does the evidence support the student's claim? Use specific data from the table to justify your answer.(2 points) C. Identify the independent variable and dependent variable in this investigation.(1 point) D. Explain how adaptations and natural selection could cause a microbial population to change over multiple generations if it were repeatedly exposed to high-salt conditions.(2 points)
