- Now prepare a 500 ml media having ¼ strength MS with 5mM BAP, 5.5 mg/l Kn and coconut water 10%. Stocks are MS Macro 10X, micro 20X, FeEDTA 10X, Organic 100X, BAP and Kn 5gm/100ml. If you need anything else then you add accordingly. BAP has a MW of 225.3. Sucrose and Myo-inositol is not mentioned in the question. These you need to add. Consistency of the medium is also mentioned.On a paper, draw a schematic diagram on the Extraction of Flavonoids using the procedures stated below. Procedure: Extraction of Flavonoids Weigh 10 g of the shade dried plant sample and chop into small pieces. Macerate with 200 mL 70% ethanol for 3 days at room temperature (25°C). Filter the extracts in vacuum using Whatman filter. Evaporate to dryness. Weigh the residue and compute the percentage yield.The solution was graded as incorrect in my homework.

- A plant isolate was subjected to qualitative tests to determine the presence of macromolecules. Below is a summary of results obtained: Biuret Ninhydrin Schiff's Test for Test for Deoxyribose Phosphat test test test Violet Violet Pink Blue Yellow solution solution solution solution precipitat To form a definitive conclusion about the isolate, what additional test is needed (if any)? O Wheeler-Johnson Test Sakaguchi Test Molisch Test Dische Diphenylamine TestAspergillus can be used to produce α-amylase (α-AM), which is an enzyme that hydrolyzes the glycosidic bonds in starch molecules into maltose (disaccharide). Pure α-AM has a specific activity of 56.00 U/mg. The α-AM is secreted into the culture media during production (after 5 days, production is complete). Following, the Aspergilluscells are separated by centrifugation and discarded. The culture supernatant (with α-AM) is filtered giving a clarified supernatant with a volume of 100.0 L, activity of 3.00 U/mL, and total protein concentration of 0.650 mg/mL. After purification, the product stream (7.50 L) contains α-AM (25.00 U/mL) and a total of 6.788 x 103 mg total protein. Calculate the following: Concentration of total protein (g/L) and total units of activity in the clarified supernatant and purification product stream. Specific activities (U/g) of the clarified supernatant and purification product stream. Consider significant figures in your answers (may want to use scientific…Instead of Molisch's test, what specific test can be used to detect the presence of pentose sugar? Write the procedure
