fostered was unnecessarily lost‚ too.” Even though we recognize that energy is not a physical substance‚ we choose to use the substance metaphor to describe it. We’ll use three principles to guide us in the development of the energy concept. 1. Energy can be viewed as a substance-like quantity that can be stored in a physical system. 2. Energy can “flow” or be “transferred” from one system to another and so cause changes. 3. Energy maintains its identity after being transferred. If

Folic Acid is a B vitamin‚ specifically B9. It is an essential nutrient required by the body to create healthy new cells. While we hear about it mostly in regards to pregnancy‚ it is important to understand that the need for folic acid goes even beyond this. Folic acid is essential for the body to create red blood cells which in turn prevents anemia. It is also plays an important role in the metabolism of homocysteine‚ an amino acid. The recommended dietary allowance (RDA) for all men and women
