A labor-hour contract is a variation of the time-and-materials contract, differing only in that materials are not supplied by the contractor. See 12.207(b), 16.601(c), and 16.601(d) for application and limitations, for time-and-materials contracts that also apply to labor-hour contracts.
Appraising the brain's energy budget. In the average adult human, the brain represents about 2% of the body weight. Remarkably, despite its relatively small size, the brain accounts for about 20% of the oxygen and, hence, calories consumed by the body (1). This high rate of metabolism is remarkably constant despite widely varying mental and motoric activity (2).
FALSE:::::::: Up to 60 percent of the human body is water, the brain is composed of 70 percent water, and the lungs are nearly 90 percent water. About 83 percent of our blood is water, which helps digest our food, transport waste, and control body temperature. Each day humans must replace 2.4 litres of water, some through drinking and the rest taken by the body from the foods eaten.
