Consider Snarlsville, a city that will vote on a proposed revenue-neutral con- gestion tax. Consider the following statement from the Chamber of Commerce: The tax will be bad for business, so we urge all business owners to vote NO. Suppose bad for business means sales revenue will decrease. a. The co

Rent Control and Elasticity Consider the effects of rent control in two cities, each of which imposes rent control with a maximum price of $400, compared to an equilibrium price of $500. In Elastic City, the price elasticity of supply of housing is 5.0. In Rigid City, the supply elasticity is 0.40. a

Phagocytosis allows amoebae to move and pseudopodia help in the uptake of nutrients. c. Phagocytosis helps amoebae to take up nutrients and cilia help a

Biology: The Unity and Diversity of Life 15
Bluebirds are songbirds that, like wood ducks, nest in cavities in trees. European house sparrows, which have been introduced to North America, also nest in such cavities. Explain how the arrival of the house sparrows affected the carrying capacity for bluebirds. What affect would you expect this cha
