Problem: - Blood sugar levels increase after a meal - Cells in the pancreas release insulin - Insulin causes the body to absorb glucose from the blood - Blood sugar goes back to normal - Blood sugar is too low - The amount of insulin goes down - Cells in the pancreas release glucagon - The liver turns stored glycogen into glucose - The liver releases the glucose into the blood What might be the last step of the process?

A: Blood sugar goes back to normal.

Problem: - There is a rain cloud in the sky - Small bits of ice within the cloud bump each other - The collisions create electrical charge - Lighter, positively charged particles sink to the bottom of the cloud - Heavier, negatively charges particles rise to the top What might be the last step of the process?

A: When the positive and negative charges grow large enough, a giant spark, called lightning occurs

Problem: - Fluid - Waste enters the kidneys - A processing moment in the kidneys let waste and fluid pass - Prevents larger molecules to pass - Fluid goes back to the bloodstream - Bad waste is removed What might be the last step of the process?

A: The final product is turned into urine.

Problem: - Magma moves closer to the Earth's crust - The magma starts to cool - The cooling causes atoms in the magma to condense - The condensed magma solidifies What might be the last step of the process?

A:
The solidified magma forms minerals.
