Iodine solution stops cytoplasmic streaming by disrupting the cytoskeleton of plant cells. Iodine is a strong oxidizing agent that can denature proteins, including those involved in cytoplasmic streaming. This disruption leads to a cessation of the movement of cytoplasm within the cell.

Why did iodine stop turning blue-black?
Iodine turns blue-black when it comes in contact with starch because it forms a complex with the starch molecules. If iodine stopped turning blue-black, it could be due to the absence of starch, chemical interference with the reaction, expired iodine solution, or improper storage conditions affecting the reactivity of the iodine.
What disease is caused by inadequate intake of iodine?
Iodine is used to produce the hormones thyroxin and tri-iodothyroxin in the thyroid. With iodine deficiency the body can no longer produce these hormones. These hormones are controlled by negative feedback, meaning that these hormones decrease their own production in the thryoid. So without thyroxin and tri-iodothyroxin there is no longer a signal to stop production by the thyroid and therefore the thyroid goes into overdrive while the body loses its thyroid hormones. This results in a goiter(enlargment of thyroid) and HYPOthyroidism(look up symptoms on wikipedia). Iodine deficiency is extremely rare in all developed nations because we add iodine to salt. Hope that helps.
How can you prevent oxidation of sodium metabisulfite in solution Is pH an important factor in controlling oxidation of metabisulfite will glycerol addition stop oxidation of metabisulfite?
You can prevent oxidation of sodium metabisulfite in solution by storing it in a cool, dark place with minimal exposure to air. pH is an important factor in controlling oxidation, as lower pH levels can help stabilize metabisulfite and reduce oxidation. Adding glycerol may not necessarily stop oxidation of metabisulfite, but it could potentially help to slow down the process by acting as a stabilizer.
Explain how you would prepare a saturated solution of potassium nitrate in water?
Add potassium nitrate to distilled water while stirring continuously; stop adding potassium nitrate once the chemical becomes saturated and stops dissolving in the water. Filter the solution into an evaporating dish and measure the temperature of the solution. Measure the temperature and carefully heat the solution under low heat. Weigh the potassium nitrate to determine its solubility. You should find that approximately 36 g of potassium nitrate can be dissolved in 100 ml of water at room temperature (25 degrees Celsius). santosh kumar.batchu santoshkumar@gmail.com
What are the solution to stop ground water pollution?
Some solutions to stop groundwater pollution include implementing strict regulations on industrial and agricultural practices, promoting sustainable land use and waste management practices, and increasing public awareness about the importance of protecting groundwater sources. Additionally, regular monitoring and testing of groundwater quality can help identify sources of pollution and inform remediation efforts.
Why did the mixture stop turning the drops of iodine solution blue after 240 s?
Because it didn't react with the iodine, i don't know
Why did the the mixture stop turning the drops of iodine solution blue after 240 s?
The mixture stopped turning the drops of iodine solution blue after 240 seconds due to the completion of the reaction between iodine and the other components in the mixture. Once all the iodine had reacted, there was no more available iodine to cause the blue color change.
Why did the mixture stop turning the drops of iodine solution blue after 240s?
Because it didn't react with the iodine, i don't know
Why was the mixture stop turning the drops of iodine solution blue after 240 s?
The reaction between iodine and starch forms a blue-black complex. Once all the starch present in the solution has reacted with the iodine, no more blue color will be observed. This explains why the mixture stopped turning the drops of iodine solution blue after 240 seconds.
Why did the mixture stop turning the drops of iodine solution blue after 240 seconds?
The reaction between iodine and starch is complete after a certain period of time, typically around 2-4 minutes. Once all the available starch molecules have formed a complex with iodine, there are no more free starch molecules for the iodine to react with, resulting in the iodine solution no longer turning blue.
Why does Lugol's iodine solution cause the movement of chloroplasts to stop?
Lugol's iodine solution disrupts the process of photosynthesis in chloroplasts by inhibiting the enzymes involved in the light-dependent reactions. This disruption can lead to the cessation of chloroplast movement as the chloroplasts rely on the energy produced through photosynthesis to move.
Why did iodine stop turning blue-black?
Iodine turns blue-black when it comes in contact with starch because it forms a complex with the starch molecules. If iodine stopped turning blue-black, it could be due to the absence of starch, chemical interference with the reaction, expired iodine solution, or improper storage conditions affecting the reactivity of the iodine.
How can I safely apply iodine to my skin for medical purposes?
To safely apply iodine to your skin for medical purposes, follow these steps: Clean the area with soap and water. Use a cotton ball or swab to apply the iodine solution to the affected area. Allow the iodine to dry before covering with a bandage. Avoid getting iodine in your eyes, mouth, or open wounds. If you experience any irritation or allergic reaction, stop using iodine and seek medical advice.
Why does a mixture of enzyme stop turning the drops of iodine soloution?
When a mixture of enzymes stops turning drops of iodine solution, it is likely because the enzyme has catalyzed the reaction that converts starch into glucose, which iodine detects by changing from a blue-black color to a brown or yellow color. Once all the starch has been broken down into glucose, there is no longer any substrate for the iodine to react with, so it remains in its original blue-black color.
Which chemical is using for dehorning in cow?
Caustic paste is used for dehorning calves, not cows. If a cow was dehorned, a dehorner (a tool used to dehorn cattle) is used, then an iodine solution or a hot-iron is used to stop the bleeding.
What can I do to make sure that I am not streaming videos that will slow my internet connection?
Sites like YouTube stream videos. Video streaming will slow down your internet connection because it uses a lot of bandwidth. You can easily determine if you are streaming a video and stop it. Just close any video sites that you have open in your web browser and you will not be streaming anymore.
Who created a solution to stop racism?
No one has.
