Answer:
1.25
Explanation:
Index of refraction also known as refractive index determines the speed of the light in the particular material. The light can bend towards the normal or away from the normal in the particular media.
Different objects have different index of refraction. The amount of the light refracted by the media can be calculated by the help of the refractive index. The refractive index of an actual material is 1.25. The refractive index of the media depends on the density of the substance.
Thus, the correct answer is option (D).
C) it absorbs water hope that helps
Answer:
A chromosome is made up of two chromatids which are joined by the centromere. The chromatids separate from each other during mitosis to form two new chromosomes. The DNA making up a chromosome is dispersed as chromatin. ... Each copy is called a chromatid.
Explanation:
Scientists use several methods to determine the proximity between species. Two of those methods may be an anatomical comparison, by examining the skeleton structure of two species, and DNA composition comparison, by comparison of genes, or specific parts of the DNA, that allow establishing the relative distance between species.
