In the opener of Season 4, the two characters are revealed to be dating, and as such, other character romances, such as the romance between fellow co-workers Dwight Schrute and Angela Martin, begin to move more toward the forefront of episodes. In Season 6, Jim and Pam are married in the season's 4th and 5th episodes (hour long), a feat considered noteworthy by many television critics, as bringing together the two lead love interests in a television series is often thought to be a risky venture. Their child is born in the second half of the season, during another hour long, ``The Delivery''. Pam and Jim's second child is born during season 8. In season 9, their marriage becomes strained when Jim takes up a second job in Philadelphia. They ultimately decide to leave Dunder Mifflin together so Jim can pursue his dream job.

Minerals originate in the earth and cannot be made by living organisms. Plants get minerals from soil. Most of the minerals in a human diet come from eating plants and animals or from drinking water. As a group, minerals are one of the four groups of essential nutrients, the others of which are vitamins, essential fatty acids, and essential amino acids. The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium. All of the remaining elements in a human body are called ``trace elements''. The trace elements that have a specific biochemical function in the human body are sulfur, iron, chlorine, cobalt, copper, zinc, manganese, molybdenum, iodine and selenium.
