Vitamins and Minerals Vitamins and minerals are essential nutrients that every cell needs. Vitamins can function like hormones or as antioxidants. Minerals are essential to important bodily functions such as producing energy‚ growing‚ and healing. Minerals are required for fluid balance‚ development‚ nervous system maintenance .Minerals and vitamins‚ function as coenzymes and participate in enzymatic reactions in the body. Vitamin and mineral deficiencies can affect the brain many different ways

Unit 1 Research Assignment 1: Integrated Circuit Technology An integrated circuit is a tiny complex of electronic components and their connections that are produced in or on a small slice of material. A MOSFET‚ (Metal Oxide Semiconductor Field Effect Transistor)‚ is the type of transistor used in modern computers. In the most basic form they are an amplifier. They typically have three pins - a source‚ a drain‚ and a gate. When there is voltage (not current) on the gate then the MOSFET

Topic 12 ATOMIC STRUCTURE: Electronic configuration 12. 1. Ionization energy If an electron obtains enough energy it jumps beyond the highest energy level and becomes a free electron: the atom itself becomes a positive ion. This electron transition is represented as follows: n = 1 to n = (. Notation n = ( refers to the “world” outside the atom – beyond the control of the nucleus; any electron outside an atom has no potential energy (energy = 0). With hydrogen the ionization energy can be
