Answer: provides protection and transports nutrients
The correct answer should be<span> D) conserving natural resources without harming the environment
Instead of using new resources, you can use the waste from previous production and recycle it for the sake of creating something else, which preserves the resoruces and doesn't harm the environment.</span>
2 or more different atoms are combined in definite proportions in any compound.
The relationship between the wavelength of light and the quantity of energy per photon (b) they are inversely related.
Wavelength of light is defined as the distance between two crest or trough of the waves of light. The wavelength is denoted by the letter lambda (λ). Photon is simple a packet of light. It is an elementary particle that is a quantum of the electromagnetic field.
According to the Planck-Einstein relation,
E = hν (where, E = Energy of photon; h = Planck's constant and ν = frequency of oscillation)
ν = c/λ (where c = speed of light and λ = wavelength)
Therefore, E = h (c/λ)
Hence, Energy per photon is inversely proportional to wavelength of light.
