Context: The NBA high school draftees are players who have been drafted to the National Basketball Association (NBA) straight out of high school without playing basketball at the collegiate level. The process of jumping directly from high school to the professional level is also known as going prep-to-pro. Since 2006, the practice of drafting high school players has been prohibited by the new collective bargaining agreement, which requires that players who entered the draft be 19 years of age and at least one year removed from high school. Contrary to popular belief, the player does not have to play at least a year in college basketball, as the player can choose to instead play in another professional league (like the NBA G League or especially somewhere overseas) like Brandon Jennings or Emmanuel Mudiay in Italy and China respectively, simply take the year off, such as the case with Mitchell Robinson, or even hold themselves back a year in high school before declaring for the draft, like with Satnam Singh Bhamara or Thon Maker.
 Question: does the nba draft out of high school Context: In the context of nutrition, a mineral is a chemical element required as an essential nutrient by organisms to perform functions necessary for life. 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.

The extra lumbar and thoracic vertebrae account for the cat's enhanced spinal mobility and flexibility, compared to humans. The caudal vertebrae form the tail, used by the cat as a counterbalance to the body during quick movements. Between their vertebrae, they have elastic discs, useful for cushioning the jump landings.

George works with Addison to convince Bailey to have the baby. He finally gets through to Bailey by giving her the motivation that she needs, and ultimately he holds her while she delivers the baby. Izzie and Alex have sex again. Chief Richard Webber is under a lot of stress from everything that's been going on, and it is believed that he is having a heart attack, which lures his wife Adele to the hospital. However, it proves to be just an anxiety attack. Dr. Bailey's husband goes into cardiac arrest. Meredith finally removes the explosive from the patient, and Dylan, the leader of the bomb squad, carries it away. Meredith steps out of the operating room into the hallway, curiously watching Dylan walk away with the explosive, and at that moment, the bomb explodes, killing Dylan and a second bomb squad member. Meredith is knocked unconscious by the explosion. There is a revival of the ``shower scene'' from the first part, but with a more serious tone: the fully clothed Izzie and Cristina wash blood off of a stunned Meredith as George looks on. Dr. Bailey's husband and the man who had the explosive embedded in his body both survive. At the end of the episode, Preston and Derek become friends, overcoming their initial rivalry in the series beginning, and call each other by their first names. Cristina says ``I love you, too'' to a sleeping Preston. Derek comes to visit Meredith and says, ``You almost died today,'' and Meredith tells him that she can't remember their last kiss. Derek recalls the kiss for her, telling her that she ``smelled like some kind of flower,'' which Meredith says was lavender, and then he leaves.
