Answer:
Individuals of a species are not identical, Traits are passed from generation to generation, more offspring are born that can survive,and only the surviovrs of the competition for resources will reproduce.
Explanation:
Heat from the sun moves through space by the process called <span>electromagnetic radiation.
H</span>eat moves<span> in three different ways. They are radiation, conduction, and convection. Radiation happens when </span>heat moves<span> as energy waves, which are called infrared waves, directly from its source to something else. This is how the </span>heat from the Sun<span> gets to Earth.

Answer:Dark matter is invisible and does not emit electromagnetic radiation. Dark matter is part of a theory that hypothesis the existence of a counterpart to the particles we know in physics, in order to balance the universe that otherwise would be largely unbalanced right now. However, the theory right now is not yet proven.
Explanation:done
Explanation:
The effects of gamma radiation are investigated by studying plant germination, growth and development, and biochemical characteristics of maize. Maize dry seeds are exposed to a gamma source at doses ranging from 0.1 to 1 kGy. Our results show that the germination potential, expressed through the final germination percentage and the germination index, as well as the physiological parameters of maize seedlings (root and shoot lengths) decreased by increasing the irradiation dose. Moreover, plants derived from seeds exposed at higher doses did not survive more than 10 days. Biochemical differences based on photosynthetic pigment (chlorophyll a, chlorophyll b, carotenoids) content revealed an inversely proportional relationship to doses of exposure. Furthermore, the concentration of chlorophyll a was higher than chlorophyll b in both irradiated and non-irradiated seedlings. Electron spin resonance spectroscopy used to evaluate the amount of free radicals induced by gamma ray treatment demonstrates that the relative concentration of radiation-induced free radicals depends linearly on the absorbed
