Step by step solution

01

introduction

Geographic separation of a population into two isolated populations is known as allopatric speciation. Flooding that results in the development of a new lake would result in the population being split geographically, with one population on one side of the lake and the other on the other. Allopatric speciation would result. Following that, these two geographically isolated populations will evolve.

As an individual consumes more units of an item, the person eventually experiences diminishing marginal utility. This means that to increase marginal utility, the person must consume less of an item. Explain the logic of this behavior using the example in Problem 20-1.

Why might two people diagnosed with exactly the same type of pain-inducing physical problem opt to place different levels of daily stress on their bodies?

Draw a marginal utility curve corresponding to the total utility curve depicted in Problem 20-9.

You determine that your daily consumption of soft drinks is 3and your daily consumption of tacos is 4when the prices per unit are 50cents and $1, respectively. Explain what happens to your consumption bundle, and, after your consumption choices adjust, to the marginal utility of soft drinks and the marginal utility of tacos, when the price of soft drinks rises to 75cents.
