Aspaceship is designed to support animal life for a multiyear voyage to the outer planets of the solar system. plants will be grown to provide oxygen and to recycle carbon dioxide.; since the spaceship will be too far from the sun for photosynthesis, an artificial light source will be needed. what wavelengths of light should be used to maximize plant growth with a minimum of energy expenditure? ; a) full-spectrum white light; b) green light; c) a mixture of blue and red light; d) yellow light; e) uv light

Mixture of blue and red light

Explanation:

This wavelength of light will maximize plant growth with minimum of energy expenditure compared to the rest of the options

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
