The reason for systematic insecticides not working properly against the chewing insects. Introduction: Insecticides are the substances that are used to kill the insects feeding on plant sap. The using of insecticides in a large amount is harmful to our health as well as for the growth of the plants. For the management of the use of insecticides various approaches are taken like integrated pest control (IPC).

Give typing answer with explanation and conclusion

Acid rain can have a pH between 1.5 and 5.0. The effect of acid rain on the environment depends on the pH of the rain and the characteristics of the environment. It appears that acid rain has a negative effect on plants. The scale below shows the pH of normal rain. Provide the information requestec below that should be included in a research plan to test the effect of pH on the early growth of bean plants in the laboratory. Which of the following would be the dependent variable? (choose all that apply)kr Normal rain 12 3 45 6 7 89 10111213 14 pH Scale a. the pH of the rain b. the type of plant c. the amount of rain d. the height of the plant Se Which statement best describes the growth curve seen below: a. It shows only exponential growth b. It shows a decline in population c. It shows growth slowing and then remaining steady d. It shows extinction
