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.
The short-run marginal cost (MC) curve will at first decline and then will go up at some point, and will intersect the average total cost and average variable cost curves at their minimum points.
The average variable cost (AVC) = 53Q/Q=53. c. The marginal cost = change in total cost / change in quantity of output. The total cost increases by 53 if the firm increases output by one unit. Thus the marginal cost is 53. d. C=45Q+240: The new fixed cost is 190+50=240, and the marginal cost is 45.
