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 U-shape of the marginal cost curve is directly attributable to increasing, then decreasing marginal returns (and the law of diminishing marginal returns). As marginal product (and marginal returns) increases for relatively small output quantities, marginal cost declines.
This is computed by taking the change in total revenue divided by the change in output. If costs increase by $80 by producing two more units of output, then the marginal cost per unit of output would be $40. A marginal benefit of $50 compared to the Marginal Cost of $40 would indicate that this would be a wise choice.Although we may not explicitly write down the marginal benefit and marginal cost of each choice we face, we subconsciously do this every time we make a choice.his is computed by taking the change in total revenue divided by the change in output.
