The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
So an object denser than water will sink
Protein becomes denatured and cease to perform the work if structural changes occur because protein is highly specific in its function. It is stated that the function of the protein is determined by its structure. The proteins are the product of the continuous process of replication, transcription, translation and post-translational modifications. The information stored in it highly specific.
Protein binds with other molecules and perform various physiological functions as it has specific complementary attachment sites, the alteration in the structure would not let it bind to the target and hence desired result will not come out.
