Main articles: Growth hormone 1 and Growth hormone 2. Genes for human growth hormone, known as growth hormone 1 (somatotropin) and growth hormone 2, are localized in the q22-24 region of chromosome 17 and are closely related to human chorionic somatomammotropin (also known as placental lactogen) genes.
Average costs are U-shaped, and the marginal cost curve intersects the average cost curves at their respective minimum points. In the competitive model of the firm, the minimum average variable cost is termed the shutdown point because a firm will not produce in the short run if price is below average variable cost.
CHARACTERISTICS OF THE MARGINAL COST CURVE 473 pounds, 6500 pounds become interval number 13; 7000 pounds, interval number 14; etc. But in Table 44, average costs are given per 100 pounds output even though output is again shown as 6500, 7000, etc. pounds.
