djverab [1.8K]

Answer:

Ultraviolet Light

Light with a wavelength immediately shorter than any light in the visible spectrum is called Ultraviolet Light.

Explanation:

Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers

As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers

Natali5045456 [20]

Answer:

amount of variation in athletic ability in an entire population that is due to differences in their genes.

Explanation:

Heritability score is a number that indicates the proportion of a trait that is genetic. Inheritance is the ratio of genetic variation to the total variation of a given attribute in a population. Variation of a trait in the population is referred to as phenotypic variation, while genetic variation in a population is referred to as genotypic variation. Thus, heritability is a ratio of genotypic variation to phenotypic variation. Based on this, we can state that the heritability score for athletic ability estimates the amount of variation in athletic ability in an entire population due to differences in their genes.
