What is dark violet iodine crystals.. is it a chemical change or not?
In order for something to be considered a change some sort of change must occur. A crystal is an object, not a type of change. Dark violet iodine crystals are pieces of relatively pure elemental iodine.
What is the ploidy level of endosperm of gymnosperm?
Endosperm of gymnosperm is haploid(ploidy n), develop from megaspore (n) before fertilization. ploidy of endosperm in angiosperm is 3n(central cell fused with one male gamete i.e 2n+n).
What is the formula of iodine crystals?
Iodine exists as I2. The crystal of iodine is formed simply by the interaction of iodine molecules as a result of Van de Waals forces, which allows for these molecules to bond together to form a solid.
Goiters are a result of a deficiency of what substance in the body?
Goiters are often the result of iodine deficiency in the body. Iodine is necessary for the production of thyroid hormones, and a lack of it can lead to the enlargement of the thyroid gland, causing a goiter.
When you warm the test tube crystal of iodine what is the result?
it result to the formation of metal sulfates
Triploid endosperm nucleus is a result of?
Triploid endosperm nucleus is a result of double fertilization in angiosperms, where one sperm fertilizes the egg cell to form the diploid zygote and the other sperm fertilizes the central cell to form the triploid endosperm. The endosperm serves as a nutrient source for the developing embryo.

Why would a negative iodine test for starch indicate a positive result for the enzymatic degradation of starch by amylase?
A negative iodine test for starch indicates that the starch has been broken down by amylase into simpler sugars, such as maltose or glucose, that do not react with iodine. Therefore, the absence of a starch-iodine complex formation suggests that amylase has successfully degraded the starch substrate.
What is the disease of the endocrine system which is the result of lack of iodine?
Iodine deficiency is the most common cause of hypothyroidism worldwide.
What result is yield when iodine place in potato juice?
When iodine is placed in potato juice it turns dark purple to black. It's the starch in potatoes that reacts with the iodine.

Which of the halogens is used as goitre control?
Iodine is used as a goitre control because it is essential for the production of thyroid hormones. Goitre can result from iodine deficiency, so supplementing with iodine can help prevent and treat this condition.
Why Did Glucose Give Negative Result in iodine test?
Glucose gives a negative result in the iodine test because iodine primarily reacts with starch, forming a blue-black complex. Glucose, being a simple monosaccharide, does not have the helical structure that starch possesses, which is necessary for the iodine to bind effectively. Therefore, when iodine is added to a solution containing glucose, no color change occurs, resulting in a negative test.
What is the result of hypothyroidism?
Hypothyroidism is a lack of iodine or a specific kind of salt.
