Multiple Choice

Figure 5-11
-Refer to Figure 5-11.Suppose this demand curve is a straight,downward-sloping line all the way from the horizontal intercept to the vertical intercept.We choose two prices,P₁ and P₂,and the corresponding quantities demanded,Q₁ and Q₂,for the purpose of calculating the price elasticity of demand.Also suppose P₂ > P₁.In which of the following cases could we possibly find that (i) demand is elastic and (ii) a decrease in price from P₁ to P₂ causes an decrease in total revenue?

• A)0 < P₁ < P₂ < $10.
• B)$10 < P₁ < P₂ < $20.
• C)P₁ > $20.
• D)None of the above is correct.

Understand the concept of evolutionary change in traits and the conditions under which it may or may not occur.

Differentiate between broad sense heritability and narrow sense heritability in genetic terms.

Identify the types of selection (directional, stabilizing, disruptive) and predict their effects on trait distribution.

Comprehend how environmental challenges can lead to adaptive evolution in species.

Definitions:

Marginal Product

The additional output that results from the use of one more unit of a production input, holding all other inputs constant.

Nonlabor Resources

Inputs used in the production of goods and services that do not involve human labor, such as capital, land, and natural resources.

Average Product

The output per unit of input, such as labor or capital, calculated by dividing total production by the number of input units.

Nonlabor Resources

Assets or inputs in production that are not related to direct human labor, such as machinery, raw materials, and land.
