The infant is then secure in his or her attachment to the caregiver. The caregiver-child relationship establishes the foundation for the development of emotional skills, and sets the stage for future social relationships. A secure attachment leaves the child free to explore the world and engage with peers.
Adding brewer's yeast to the compost pile speeds up decomposition and increases heat. For gardeners who practice vermiculture or raise worms in the compost pile for their castings, the addition of brewer's yeast increases the growth of worms and the quantity and quality of worm castings produced.
Yeast is a leavening agent. Yeast releases CO2 as a waste product. Bread dough has protein structures called Gluten. The CO2 from the yeast gets trapped in pockets between the gluten strands, thus causing the dough to rise. When the bread bakes, the yeast continues to reproduce and create CO2 gas. The yeast eventually dies when the temperature of the dough gets hot enough. Without yeast, bread would be flat and tough.
