bleaching removes the chlorophyll pigments from the leaf, making it easier to observe the starch produced during the starch test. Chlorophyll can interfere with the detection of starch as it also gives a green color to the leaf. By bleaching the leaf, we can ensure that any starch present is more visually distinguishable.
Starch is not included in the bag because it is used as a thickening agent in the soup and would not have the same texture or flavor profile if it was included in the bag before cooking.
a leaf (plant) should be destarched before photosynthesis investigations because the starch already present in the plant may mislead the result . hence if a destarched plant is used for the experiment then the amount of starch present at the time of the experiment will be nil and affter the experiment is compleded the amount of starch present in the leaves woul give the rate of photodynthesis as starch id prepared during photosynthesis
Destarching a leaf is a method used in an experiment to prove that there is starch exsisting within the leaf, Destarching a leaf is also a preparation used before the experiment, to remove all starches within the leaf-NR
It does not digest starch faster. The saliva produced before the meal will have a longer time to prepare.
starch gives more energy than sugar because starch is a polysaccharide(polymer of sugar).
The hypothesis of testing leaves for starch is that leaves produce starch through photosynthesis and store it for energy. By conducting a test to detect the presence of starch in leaves, we can determine if photosynthesis has occurred in the leaf tissue being tested.
Starch does not have a specific melting point because it undergoes thermal decomposition before melting. Instead of melting, starch will break down into simpler compounds when heated to high temperatures.
Your body cannot use starch because it is a complex carbohydrate. It must be broken down into shorter carbohydrate strings before being converted into energy
Starch is not included in the bag because it is used as a thickening agent in the soup and would not have the same texture or flavor profile if it was included in the bag before cooking.
Boiling saliva before mixing it with starch would denature the enzymes in saliva that break down starch. This would prevent the starch from being properly digested and broken down into simpler sugars.

You'll need to explain what it will be used for before anyone can suggest which starch will work.
Because starch is a polymer of sugar molecules (lots of them all bound together as a store of sugar) and the cells in the body can only metabolize individual sugar molecules. Therefore the starch needs to be broken up into its individual sugars before it is any use to the cells.

Starch is used in amylase determination as a substrate to measure the activity of the enzyme amylase. The enzyme amylase breaks down starch into simpler sugars, and by monitoring this process, the activity of amylase can be quantified. Starch provides a standardized substrate for conducting experiments to accurately measure the enzyme's activity.
It does not digest starch faster. The saliva produced before the meal will have a longer time to prepare.
Test tube 4A had no amylase enzyme added, which is needed to break down starch into simpler sugars. Without amylase, the starch molecule could not be broken down, resulting in very little to no starch digestion in test tube 4A.
