Sandblasted: More smooth because all the rough edges are "blasted" away. And slightly smaller because of the loss of the edges.
Non-Sandblasted: Not smooth; rough.
oxygen -17 and oxygen-18 are isotopes of oxygen
<em><u>Explanation</u></em>
Isotope is two or more forms of the same element that has equal amount of proton but different number of neutrons in the nuclei.
oxygen -17 and oxygen-18 are isotope of oxygen since they have the equal amount of protons but different number of neutrons in their nuclei.
that is oxygen 17 has 8 protons and 9 neutrons while oxygen 18 has 8 protons and 10 neutrons.
Photosynthesis produces glucose and oxygen.... Respiration on the other hand would produce the other options.
My guess is photosynthesis since that absorbs solar energy
