Answer:</h2>
The wavelength of <u>light</u>.
<h2>
Explanation:</h2>
The electromagnetic spectrum shows the parts of light orchestrated by their wavelengths. The range for the most part comprises of both visible as well as invisible light. Together, they are called electromagnetic radiation. They are electromagnetic in light of the fact that they comprise of both an electric field and an magnetic field, and these fields travel in wave and travel at the speed of light: 3.00 × 
m/s.
When the light gets scattered it gives out color in the form of VIBGYOR which is elaborately called as Violet, Indigo, Blue, Green, Yellow, Orange and red. These colors are arranged in the spectrum based upon the wavelength.
This type of asexual reproduction is called apomixis.
Apoximis is reproduction by special generative tissues without fertilization. It includes parthenogenesis in animals, in which the new individuals develop from unfertilized egg, and apogamy in certain plants in which the generative tissues may be the sporophyte or the gametophyte.
The correct answer is option B) their DNA sequences.
The best comparison for finding out the evolutionary relationship between two organism is the comparison of their DNA (deoxyribonucleic acid) sequence. The organisms, which are more closely related to one another share more similarity in the DNA sequence as compared to the distantly related organism, so, the comparison of the DNA can help in determining the evolutionary relationship between the organism.
The correct answer that would best complete the given statement above would be the first option. Coral reefs are built by a small organism called a polyp. The polyp creates the structure of the coral reef by building a CUP out of a calcium carbonate. The skeletons of these tiny corals s<span>ecreted by the lower portion of the polyp. Hope this answer helps.</span>
