c. (crossed out) 8. the field that applies science to the production of biological products is ______ 9. scientists can learn about the chemical composition of stars by analyzing the light they transmit to earth. 10. why won’t the method used to discover the chemical composition of stars work for the moon and planets?

Explanation:

Question 8

The field that applies science to produce biological products is Biotechnology. Biotechnology uses biological systems, organisms, or derivatives to develop or make products, like in pharmaceutical, agricultural, and industrial applications related to biological substances.

Scientists analyze the light (specifically the spectrum, like emission or absorption spectra) stars transmit to Earth. Different elements in stars produce characteristic spectral lines when light passes through or is emitted, allowing identification of chemical composition.

Stars are luminous (they produce their own light), so their light has spectral signatures of their chemical composition. The moon and planets are non - luminous; they reflect sunlight. When we analyze the light from them, we mainly get the spectral signature of the Sun's light, not their own chemical composition (unless we consider reflected light with very faint signatures, but the primary reason is they don't emit their own light like stars do, so the method of analyzing emitted light's spectrum for composition doesn't work as they don't emit light with their own chemical - based spectral lines).

Answer:

Biotechnology
