Answer: A single photon carries photon energy with a particular electromagnetic wavelength and frequency. The energy is high with higher frequency and low with longer photon’s wavelength. The energy of a photon (E) is inversely related to the wavelength of the light (λ) and given by the equation: E=hcλ Where E is the photon energy h is Planck’s constant c is the speed of light and λ is the photon’s wavelength. Why are the very short wavelengths of electromagnetic energy not useful for living things? Answer: Electromagnetic radiation is a stream of photons. Very short wavelengths possess very high energy in the photons. For instance gamma rays are generated by the decay of radioactive atoms and nuclear explosions and have the smallest wavelength and of water occurs when the light is captured and sent to the grana where it is used to split water molecules. How did the production of oxygen in the early ocean help lead to the evolution of aerobic respiration? Answer: Oxygen is used to transform nutrients into molecules of adenosine triphosphate for use as energy (aerobic respiration). The result of early oxygen production was a complete transformation of Earth’s atmosphere especially of the life that populated its surface. Works Cited Wikimedia Foundation Inc.
