Answer:
the sample contains starch and starch is stored in ground tissue.
Explanation:
It should be understood that Iodine solution is used to test leaves for the presence of starch. This will show a blue-black color, which means the presence of starch.
This process can simply be demonstrated by simply following these steps.
* Take two potted plants of the same kind.
* Keep one in the dark (or in a black box) for 72 hours and the other in the sunlight.
* Take one leaf from each of the plants.
* Put few drops of iodine solution on each of the leaves.
* The leaf kept in the sunlight will turn blue-black due to presence of starch.
* The leaf kept in the dark will not turn blue-black because of absence of starch.
In conclusion, the iodine is used to test for starch.
your answer is condensation because that is the process in the water cycle in which water is evaporated or changed into clouds.
Answer:
New discoveries in the treatment of cancer do not only centre on conventional medicine. In our haste to get to grips with a cure for cancer, natural products may be overlooked and dismissed in the fight against such an aggressive disease.
In December, the Academy of General Dentistry reported that a new study had found that simply swishing green tea around the mouth halts the growth of new oral cancer cells and breaks down and kills existing oral cancer cells. The antioxidants (polyphenols) in the tea work to remove the free radicals or oxidants and prevent gene mutations, and as an added bonus, the polyphenols can kill cancerous cells without harming normal cells and inhibiting their growth. Similarly, a chemical found in tomatoes may prevent or treat oral cancer and one derived from soybeans has been found to shrink abnormal growths that lead to cancer. While these are not cures, their activity may in the future lead to therapies that compliment conventional treatment modalities.
Perhaps combining ancient remedies with Western scientific advances is the way forward to finding an effective cure for cancer. Combrestatin – a cancer-fighting drug made from the bark of an African tree – is performing with dramatic effects in tests. The active ingredient extracted from the bark attacks the blood vessels that grow with tumors, while leaving normal blood vessels alone.
