•Its correct functioning depends on a good supply of iodine from the diet.

Destructive interference formed when the two meeting waves are out of phase and in some cases, the two wavers maxima are 180 degrees out of phase. The height of waves is determined by the wind speed, how  the long wind blows, and crucially the fetch.

The longer the duration of wave, the larger will be  the wave heights. The longer the fetch, the large will be wave heights.

Some waves jump to cross over or meet with each other. When they do, the reaction between the waves is called interference.

If at a given location, both interfering waves are supersede in the same direction (both up or both down) then it is known as constructive interference.

Molecules can have each of these forms of energy except light energy. The correct option is A.

A molecule is the smallest unit of a substance that keeps its content and properties. It is made up of two or more atoms that are joined together by chemical bonds.

Chemistry is built on molecules. The element symbol and a subscript indicating the number of atoms are used to identify molecules.

Single, neutral particles make up an atom. As neutral objects consisting of two or more atoms joined together, molecules are. A positively or negatively charged particle is called an ion.

There are three different kinds of molecules: atom-sized molecules, element-sized molecules, and compound-sized molecules.

Except for light energy, molecules can possess all of these types of energy.

Denaturation involves the breaking of many of the weak linkages, or bonds (e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural (native) state. Denatured proteins have a looser, more random structure; most are insoluble.

According to the question, The percentage of heterozygous individuals (carriers). Thus, option "C" is correct.

The Hardy-Weinberg equilibrium theory states that the allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,  

p is the frequency of the dominant allele,  

q is the frequency of the recessive allele.

The genotypic frequencies after one generation are  

p² (H0m0zyg0us dominant genotypic frequency),  

2pq (Heter0zyg0us genotypic frequency),  

q² (H0m0zyg0us recessive genotypic frequency)
