3. Was there any noticeable effect on the germination rate of the radish seeds as a result of the pH? Compare and contrast the growth rate for the control with the alkaline and acidic solutions. 4. According to your results would you say that the radish has a broad pH tolerance? Why or why not? Use your data to support your answer. 5. Knowing that acid rain has a pH of 2-3 would you conclude that crop species with a narrow soil pH range are in trouble? Is acid rain a problem for plant species and crops?
3. Yes, there would be a noticeable effect on the germination rate of radish seeds as a result of pH. At neutral pH, the seeds germinate well. Under acidic and alkaline conditions, there occured no major effect on seed germination although the seeds sometimes swell up at pH<7 or pH >7
4.Radish does not have a broad range of pH tolerance as they show seed germination only under neutral pH. Any slighalteration in pH, disturbs the seed germination process.
5. Acid rains (pH 2 to 3) reduce the pH of the soil. So, the crop plants like radish wa very narrow pH range are greatly influenced by acid rains. These acid rains destroy the crop plants.

Hi there! I need to compare two essay into 1 essay, and make it interesting and choose couple topics which im going to talk about in my essay FIRST ESSAY “Teaching New Worlds/New Words” bell hooks Like desire, language disrupts, refuses to be contained within boundaries. It speaks itself against our will, in words and thoughts that intrude, even violate the most private spaces of mind and body. It was in my first year of college that I read Adrienne...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
