Why does plain paper turn black after a few drops if iodine are applied

Biology
1 answer:
faltersainse [42]3 years ago
3 0

When iodine reacts with starch, it is trapped in the starch's helical structure forming a blue-black precipitate. Iodine is not very water soluble, so in making an iodine solution, potassium iodide (KI) is added. This results in the formation of a triiodide complex, which is completely soluble in water.

Which organism is involved in vegetative reproduction?
Paha777 [63]

Answer:

*So I'm guessing you mean the reproduction of plants*

Bees and other insects such as butterflies and moths.

Bats also help pollinate as well in desert and tropical environments, as well as birds.

Plant reproduction could also occur if an animal eats the fruit of a plant, and proceeds to live its life, then pass (poop out) the seeds much farther from the original location of the parent plant.
