Answer:
<em><u>Nutrients help break down food to give organisms energy</u></em>
Explanation:
Nutrients are chemical substances found in every living thing on Earth. They are<em> necessary</em> to the lives of people, plants, animals, and all other organisms. <u><em>Nutrients help break down food to give organisms energy</em></u>. The human body can also synthesize some nutrients, such as <em>amino acids</em>.
Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.
Infrared spectroscopy helps to identify the atoms and molecules in the object.
The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.
The Doppler shift enables astronomers to discover extrasolar planets.
As a planet orbits its star, the star is alternately moving away from or toward us.
Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.

Thank you.........
<span>The answer is green, yellow or brick-red. If simple sugars are present, the blue solution will turn green, yellow or brick-red when combined with the food sample and heated. </span>Benedict's solution<span> is used to test for simple sugars, such as glucose. It is a clear blue solution of sodium and copper salts. When heated with the food sample, the blue solution changes color to green, yellow, and brick-red, depending on the amount of sugar.</span>
