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. "

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.

Given
Frequency of carriers for a rare autosomal recessive genetic condition
As per Hardy Weinberg's principles, frequency of carriers is represented by 
The second equation of Hardy Weinberg's principle states that -
Thus, we have only one component i.e and no other values of p or q. Thus, the information provided is not sufficient to solve the question.

Answer: A</h2>
Explanation:
The magnifiacation doesn't change. We aren't seeing a more detail or less detail view of the cells. Thus this eliminates B & C.
