We suggest starting to prep for the the SAT as early as eighth grade year. It sound early, but if a student plans on taking the SAT several times throughout high school, eighth graders can take a relaxed and long-view approach to prepping, and can plan on taking their first SAT sophomore year.

<u>ANSWER:</u>
The correct option is "The number of mice decreased".
<u>EXPLANATION:
</u>
It is clearly given in the question that the snakes depended on the mice for their survival. The snakes fed on the mice on the field. When the new method of grain spill was found, the mice could not find enough grain to eat and therefore they either left the field or died because of hunger.
`The reduced population of mice was not enough for the snakes which in turn either died or moved to another place for survival.
C₆H₁₂O₆ + O₂ ⇄ CO₂ + H₂O
There are 6 carbons on the left side, so you need at least 6 molecules of CO₂ on the right.
You also have 12 hydrogens on the left, so you need at least 6 molecules of H₂O on the right.
The reaction so far is then
C₆H₁₂O₆ + O₂ ⇄ 6 CO₂ + 6 H₂O
Now, on the left, you have a total of 6 + 2 = 8 oxygens, while on the right, you have 12 + 6 = 18 oxygens. To make up the difference, you need 6 molecules of oxygen:
C₆H₁₂O₆ + 6 O₂ ⇄ 6 CO₂ + 6 H₂O
so the sequence is 1, 6, 6, 6.
