Can the iodine test distinguish between amylose and amylopectin? What Would you look for? Can sucrose act as a reducing sugar? Explain your answer. In the acid-catalyzed hydrolysis of starch, how can you tell when the hydrolysis of starch is complete? Why does the test work this way? What is the monosaccharide that results at the end? Polysaccharides generally do not give a positive test with Fehling's solution. Why?
Section: After viewing the videos, complete this activity. When complete, save, and attach your name. Submit completed pages: 4-7. 1. List three different structures that are present in plant cells, but not in animal cells. 2. Which two plant cell structures can be readily seen in the video and images? 3.

Hi, Can someone answer this question correctly with complete solutions, please. thanks! How long does it take for water to drain through a hole in the bottom of a tank? Consider the tank pictured below, which drains through a small, round hole. Torricelli's law states that when the surface of the water is at a height h, the water drains with the velocity it would have if it fell freely from a height h (ignoring various forms of friction). Show...
12 men can complete a work in 18 days. After 5 days 6 more men joined the work. In how many days will theremaining work be completed?
Show step by step solutions. (a) Complete the expected duration, standard deviation and variance for activities A and B and enter them into the table (provided above). (b) Draw the Activity-on-node (AON) including the Start & Finish diagram and use the expected activity durations to complete a forward and backward pass (show calculations for ES,EF,LS,LF), create a table and show your work. Maritime Shipbuilding is set to start building the first of six ships and to finish this ship within...

I had clearer images. Part 1 - Making Standard solutions. 1. Into a clean, dry beaker combine the solutions from the table for each calibration solution using the appropriate pipettes. Pour the contents of the beaker into a provided cuvettes (do not fill the cuvettes to the top). Pour any excess from the sample beaker into a waste beaker, rinse the sample beaker, and continue making solutions until you have the blank and four solutions for the calibration. Calibration Solution...
