What else can I help you with?
What regent would you add to starch agar plate to detect starch hydrolsis?
Iodine should be sufficent. When starch and iodine are present they react with each other and the starch turns blackish. If your bacteria hydrolise your starch then the area will be clear instead of blackish.
What exactly is a reagent in English?
A reagent is a chemical substance that reacts with some other substance. It is common to add a specific reagent to an unknown substance to determine whether or not the substance that the particular reagent reacts to is present. (For example, add a reagent for sugar to test for the presence of sugar.)
How starch and cellulose treated to allow them to be used by the yeast?
Starch-you use an enzyme e.g. amylase to convert the starch to sugar ,add an enzyme which breaks the starch or cellulose into sugars. The yeast will then ferment the sugars. Not sure about cellulose...
What happens if you add iodine drops to a non-starch?
If you add iodine drops to a non-starch substance, such as sugar or protein, there will be no color change. Iodine is used to detect the presence of starch by turning blue-black in the presence of starch molecules. Non-starch substances will not produce this color change.
What monomers are produced from hydrolysis?
Monomers are not joined together by the process of hydrolysis. Dehydration synthesis, or condensation reaction is the process of chemically joining monomers.
What do you add to starch to make glucose?
You would add water through a hydrolysis reaction to reverse the condensation reaction (dehydration synthesis) that you started with to form the starch into a polysaccharide. All in all, you would just add WATER.
What solution is use to test starch?
Iodine-KI reagent. Add to the substance being tested directly. Result: If positive, Turns Blue/Black If negative, (absence of starch) Solution remains orange/yellow.

Does Hydrolysis involve carbon dioxide?
No it doesn't. Hydrolysis means that you "add" water.

How will you test for testing?
To test for starch you could use the Starch Test:Starch Test: Add Iodine-KI reagent to a solution or directly on a potato or other materials such as bread, crackers, or flour. A blue-black color results if starch is present. If starch amylose is not present, then the color will stay orange or yellow. Starch amylopectin does not give the color, nor does cellulose, nor do disaccharides such as sucrose in sugar.if starch is present it will turn blue/purple
Why do aldehydes and ketones add only one equivalent of Grignard reagent?
Aldehydes and ketones add only one equivalent of Grignard reagent because the reaction forms a stable intermediate that prevents further addition of the reagent.

What substance is used to test for starch?
The presence of starch can be tested with the help of Iodine. Similarly Benedict's test solution is also used to detect the presence of starch.
What happens if you add iodine drops to a non-starch?
If you add iodine drops to a non-starch substance, such as sugar or protein, there will be no color change. Iodine is used to detect the presence of starch by turning blue-black in the presence of starch molecules. Non-starch substances will not produce this color change.
How has DNS been modified to add support for IPv6?
1. A new DNS was created to allow a domain name to be associated with a 128-bit IPv6 address.
