Reading Science 1. “All elements are produced by all stars." Why is this statement not completely true?
A. All elements are produced by red giants, not all stars.
B. The properties of the star will determine the particular elements produced.
C. Only hydrogen is produced by stars; all other elements are produced through nuclear
reactions on Earth.
D. Only massive elements are produced in stars; all other elements come from nuclear
fission.

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.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther
