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.

02

Explanation

A mutation is a change in an organism's genotype that can be passed down across generations. It could result in the emergence of new species, although it does not imply geographic separation.

Consider Figure 20-1. If this individual were to contemplate consuming a seventh digital app and experience a total utility of 15 utils as a consequence, what would be the resulting marginal utility? Would the points on the total utility and marginal utility graphs in panels (a) and (b) lie higher or lower to the right of the current endpoints of those graphs?

Refer to the following table for a different consumer, and assume that each week this consumer buys only weckly subscriptions to ceonomic statistics apps and subscriptions to office productivity apps. The price of a subscription to each type of economic statistics app is \(2per week, and the price of a subscription to each office productivity app is \)60per week. If the consumer's available income is $128per week, what quantity of each item will the individual purchase each week at a consumer optimum?

Refer to the table nearby. If the subscription price for a sports app is \(2per week, the subscription price of a game app is \)1per week, and a student has $9per week to spend, what quantities will she purchase at a consumer optimum?

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

Sue's monthly budget for bottled water and soft drinks is \(23. The price of bottled water is \)1per bottle, and the price of soft drinks is$2per bottle. Calculate the slope of Sue's budget constraint. Given this information and the information provided in Problem F-3, find the combination of goods that satisfies Sue's utility-maximization problem in light of her budget constraint.
