Adding this causes the joining of protein chains, resulting in a stronger formation of dough.
What is salt?
This environmental health hazard involves disease causing agents like pathogens.
What is biological hazard?
This property of water allows water to stick to itself and helps with the transport of materials and nutrients through plants and animals.
What is cohesion?

What is photochemical smog?
What is a molecule?
When the flour is heated, it goes through this and destroys the bacteria.
What is thermal degradation?
This is a chemical hazard that interferes with the body system's ability to send and receive chemical (hormonal) signals which regulate growth, development, and sexual maturity.
What is an endocrine disruptor?
Nutrients circulate endlessly throughout the environment in complex cycles called this.
