Iodised salt (also spelled iodized salt) is table salt mixed with a minute amount of various salts of the elementiodine. The ingestion of iodineprevents iodine deficiency. Worldwide,iodine deficiency affects about two billion people and is the leading preventable cause of intellectual and developmental disabilities. Iodine is needed by our thyroid gland to help regulate the proper development and metabolism of both brain and skeleton of our body.

The biological act of receiving sound is called HEARING.Hearing involves the transmission of sound waves through the ear canal until they reach the ear drum which pass the sound to the inner ear through the middle ear. In the inner ear, the sound waves are converted into electrical impulse which is sent to the brain for interpretation via auditory nerve.
Hello. You have not informed the experiments to which the question refers, which makes it impossible for hypotheses to be formed. However, I will try to help you in the best possible way.
A hypothesis is an assumption, that is, it is a statement that the researcher believes to be true in relation to the research results, which can be proven or denied when the experiment is finished and the conclusions are established. Therefore, you must make assumptions about the results of the experiment, based on your primary visualization of them.
<span>Lay the frog on its back, spread out its limbs, and pin them to the tray. Use forceps to lift the skin between the hind legs and make a small incision with a scalpel. Continue the cut up the center of the frog's body with scissors, being careful to cut through the skin only. Use forceps to hold the skin away from the muscle while you cut, if necessary. Make horizontal incisions just above the legs and just below the arms, then fold the resulting flaps back and pin them. (You may need to use a scalpel to help separate the skin from the muscle underneath as you fold it back.)Repeat the incisions as before, this time cutting through the muscle layer to a point just below the arms. Lift the muscle with the forceps to prevent cutting the organs underneath.When you reach the area just below the arms, turn your scissors and make horizontal cuts through the hard sternum. Repeat the horizontal cuts just above the arms, and then remove the bony strips entirely. Pin the remaining muscle flaps back, just as with the skin.<span>Look into the body cavity. The yellow finger-like projections on the sides are the fat bodies. It may be necessary to remove some of these in order to see the organs clearly. Likewise, a female specimen may have well-developed eggs filling the body cavity and obscuring the organs. Remove them as necessary.</span></span>
