Species fit along a continuum of r- and K-selection; not all species show purely r traits or purely K traits. For example, sparrows produce several young per year but only live a few years, while the wandering albatross first reproduces at age 10 and then produces a single egg every other year during its 40-year life span. Compared to the albatross, the sparrow is more

Note: same information for questions 16-19. The following figure shows the production possibilities frontiers of two countries, Home and Foreign (solid lines). They produce two goods, Oil and Cars. Also shown are two indifference curves for the Home country. When the two countries open up to free and costless trade with each other, the resulting price line for the Home country is also shown as the dashed line. HOME has comparative advantage in

Note: same information for questions 16-19. The following figure shows the production possibilities frontiers of two countries, Home and Foreign (solid lines). They produce two goods, Oil and Cars. Also shown are two indifference curves for the Home country. When the two countries open up to free and costless trade with each other, the resulting price line for the Home country is also shown as the dashed line. When there is free and costless trade between the two countries, how many units of Oil will FOREIGN consume? Enter 0 if not enough information is provided. Only exact answer is accepted. Use a decimal point if needed.
