The purpose of yeast is to raise the dough when it is cooked. If yeast is not working then, you'll end up with unrisen or flat bread.
Once yeast is activated it is living.
Yes, yeast can go bad and become ineffective for baking if it is expired or not stored properly. This can result in the yeast not being able to properly ferment and leaven the dough, leading to baking failures.
To be activated, yeast needs warmth, water, and sugar.
Yeast is activated by sprinkling it over warm water (100 - 109 degrees F) with a small amount of sugar. It should sit until foamy, about 5 minutes.
Yes, yeast (even dried yeast) is a living organism and if it is not used/activated in a given time period the yeast cells will die and the yeast will not work in baking/brewing.
yes, it is not activated until you add water and sugar
Yes, yeast can expire and become ineffective for baking if it is not stored properly or if it is past its expiration date. Expired yeast may not be able to properly ferment and leaven dough, resulting in baked goods that do not rise properly.
Incubating yeast before using it in a recipe allows it to become activated and begin fermenting, which is necessary for leavening the dough or achieving the desired flavors in the final product. The incubation process helps to ensure that the yeast is alive and healthy, leading to better fermentation and rising of the dough.

The amount of yeast compared to the amount of the other ingredients
Yes, elephant toothpaste can work with dry yeast as a catalyst for the reaction. Dry yeast contains enzymes that break down hydrogen peroxide into water and oxygen, producing a rapid release of oxygen gas that creates the foamy eruption characteristic of elephant toothpaste. However, the reaction may not be as vigorous as when using liquid yeast or other catalysts like potassium iodide. It's important to ensure the yeast is activated properly for the best results.
Yeast needs to be activated before the sugar will be able to be metabolized. By incubating or warming the yeast, gives it an activation energy to begin metabolizing the sugar molecule.
