Answer:
A) hydrolysis reaction
Explanation:
hydrolysis can be explained as a chemical process whereby molecules of water is been added to a substance, and in most reaction the substance and the water molecules split to two part as a result of the addition, and there would be gaining bof hydrogen ion by fragment of the parent molecule. An example of this is saponification.
Saponification can be defined as process of converting oil fat as well as lipid to soap and alcohol through heating using aqueous alkali. Common aqueous alkali that can be used is NaOH. Soap are regarded as salt of fatty acid. Reaction between Ethanoic acid and alcohols is an example of a saponification
Here is soap chemical formula
CH3(CH2)14COO− Na+

It has to do with vibrations being able to travel through the air when the tuning fork was struck the vibrations made the air around it vibrate as well and when the vibrating fork got near the string the vibrating air made the string vibrate as well.
Measuring photosynthesis via the production of oxygen. Oxygen can be measured by counting bubbles evolved from pondweed, or by using the Audus apparatus to measure the amount of gas evolved over a period of time.
Answer:
To prove the food stored in leaves is starch "we will use a iodine indicator, if the leaf turn blue-black then it is confirmed that the leaf has starch. "
Explanation:
To prove the stored food in leaves is starch, first we will take a leaf, then we will treat the leaf in hot water followed by alcohol. The leaf will die when comes in contact with hot water and the alcohol will help us in the break down of the chlorophyll. Which will fade the green color. Now, we will put iodine, which we use as an indicator in the leaf, when it turn blue-black, it is confirmed that starch is present in the leaf. Sometimes the leaf will turn reddish brown, which depicts the absence of starch.
