FalseAnswer the following questions. Why is 80% ethyl alcohol is considered as the solvent of choice during phytochemical screening? What are the different types of extraction? Differentiate each. Differentiate Primary versus Secondary Metabolites and give examples. How are flowers, fruits and seeds dried? Explain why flowers requires greater care in drying.
- Discuss the relationship between soil resilience and factors of soil formation.What are the functions of soils in a rice field, and suggest management activities to maintain a healthy soil (a soil that can fully provide its full potential or function both to the plants and animals and the environment).Which element is responsible for causing soil salinity?At what concentration does the soil become saline?
- Soil formation is influenced by which factors? How availability of nutrients can affect the quality of soil?discuss the implications of having a good culture medium for the diagnosis of plant diseases?Describe the process of soil formation for one of the following: Tundra soil, Tropical forest soil or Prairie/grassland soil. The answer should address the impact of vegetation accumulation, impact of temperature and precipitation on the formation. You should also note the soil characteristics and reasons for them in relation to your choice.
