If a pesticide that inhibits acetylcholinesterase is present in a muscle, THE MUSCLE WILL BE CONTRACTING REPEATEDLY.
The enzyme, acetylcholinesterase is the one responsible for the termination of muscle contraction, when this enzyme is deactivated, the muscle contraction will not be turned off and the concerned muscle will contracts repeatedly.
Answer:
The correct answer will be- the color change will be observed and the solution will turn purplish-black.
Explanation:
Iodine test is performed to test the presence of the carbohydrates mainly starch.
The iodine solution is chemically called potassium iodide which forms a yellow solution. The potassium iodide solution forms a complex with a starch solution which appears a purplish-black color which shows the presence of the carbohydrates.
In the given question, if we add the iodine solution to the beaker after a certain point of time then it will still form a complex with the starch and thus beaker solution will appear darker in color.
Probably smaller bodies of water, as less water will heat up and evaporate faster.
