Information for questions 13-19 There are two countries, Home and Foreign. Labor is the only factor of production. There are two goods, X and Y. The following table shows the output of each good per hour of labor, in the two countries. Output per hour of labor Good Home Foreign Good X 10 8 Good Y 5 2 Calculate the relative price of good X with respect to good Y (that is, PX/PY) in the Home country, if the Home country is autarky. Enter a whole or decimal number, as appropriate. Enter 0 if the answer cannot be obtained with the information given. Only exact answer accepted.

The following table shows some statistics for a nation. Calculate its trade-to-GDP ratio. Enter a whole or decimal number, round to the second decimal digit. National Statistics Variable Value (millions of dollars) Consumption 194.5 GDP 278.3 Exports 30.8 Imports 41.2  

Information for questions 13-19 There are two countries, Home and Foreign. Labor is the only factor of production. There are two goods, X and Y. The following table shows the output of each good per hour of labor, in the two countries. Output per hour of labor Good Home Foreign Good X 10 8 Good Y 5 2 We have seen in class that if two countries trade with each other, total world production and consumption of at least one of the goods (and most likely of both goods) goes up, relative to the sum of the autarky values. Which best expresses the reason for that increase?

Information for questions 20-24 The figure below depicts the production possibilities curve (PPC) of a country. It also depicts the consumption possibilities curve (CPC) when the country is engaged in trade with one other country. Point C is this country’s consumption when that trade occurs. Considering both this country and the other country, this country has absolute advantage in:

Information for questions 10-12 The world is made of three countries, A, B, and C. There are no transportation costs among these countries, just (possibly) tariffs. Countries A and B are considering forming a Regional Trade Agreement (RTA). If they do so, then they will have no tariffs against each other’s goods, but will keep their tariffs against country C’s goods. The following table lists the costs of production per unit of steel in the three countries, and also the tariffs that A imposes on steel from country B and C before the RTA is formed. Costs of production and tariffs  Country Cost of production ($/unit of steel produced) A’s tariff ($/unit of steel imported) Country A 21   Country B 15 5 Country C 11 5 This example features

Which subjects were in the sample(s) used in the study? Are the sampling methods random? Explain your reasoning. 

A REMINDER: We do chapter quizzes as a way to study each week for the upcoming major exam. A best practices approach: (a) do the quiz after having read the chapter and having used the required PowerPoint, then (b) allow time, so that immediately after the quiz, go to the chapter and look for and highlight facts and terms you remember from the quiz–accumulate those highlights and notes to use for later studying. AND ALSO, we do room scans before starting a quiz and often within the quiz, including now–EVEN IF YOU DID THE ROOM SCAN before starting the quiz: pick up your laptop and point it toward the desktop area in front of where your computer sits, hold it for 5 seconds, then scan slowly left, then scan slowly right to show the right area of your work space, then continue the scan around to the area directly behind you. Use a football size or larger mirror to do the scan if you use a desktop instead of laptop computer. Either way, do the scan slowly enough to clearly show your work environment. When done, return to your standard testing set-up and continue with the quiz, doing this question: THEN…Select True as the answer if you did a laptop scan and False if you used a mirror, then keep moving forward.

Over many generations, natural selection favors those traits that enable populations to live successfully in a particular habitat. A scientist discovered two species of anole lizards that live in different habitats and display the characteristics listed in the table below. (The scientists based these observations on a sample of 20 lizards from each species.)  Screenshot 2026-01-25 at 3.12.48 PM.pngAnswer these questions: Describe all of the differences between the two species of anoles. (3 points) Formulate one hypothesis to explain why each of these differences may have evolved. (2 points)

Please copy and paste the essay question of your choice from the review sheet. Below is the list.  Only answer one of these:Convergent Evolution and Island Biogeography: Discuss how the Caribbean anole lizards serve as a model for convergent evolution. Explain why islands are often referred to as “natural laboratories” for observing these evolutionary processes.The Dinosaur-Bird Transition: Analyze the shift in scientific consensus regarding the origin of birds. How did specific fossil discoveries like Deinonychus and Sinosauropteryx challenge the view that dinosaurs were merely “slow, cold-blooded, and lumbering”?Molecular vs. Morphological Evidence: Using the anole ecomorph study and the cetacean-hippo connection, evaluate the roles of DNA sequencing and physical morphology in constructing phylogenetic trees. Which is considered the “gold standard” and why?Mechanisms of Speciation: Define reproductive isolation and explain how microevolutionary changes within a population (such as changes in leg length or dewlap color) can eventually lead to macroevolutionary events like the formation of new species.

In a sentence or two, explain why it is incorrect to use the term “missing link.”  In your answer, be sure to use the appropriate term that should be used instead of “missing link.”
