Which term is used to describe the variety of inheritable traits in a species? (i know its not a) ecosystem diversity genetic diversity natural selection species diversity

The term which specifies about the diverse nature of traits in a species which are inheritable is the “Ecosystem Diversity”.  

Option A

Explanation:

In an ecosystem, there are various forms of biological diversity which is being studied and are coined with term for the distinction.

One such term is ecosystem diversity, here the diversity is acknowledged in the forms of variation seen in the species according to the traits which can be inherited through out the generation.

This ecosystem belongs to a particular geographical area with an impact over the environment.

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
