here is a diagram of a chordate. identify and name the four basic characteristics of this phylum.
1. A major evolutionary event in chordate evolution is represented by: the occurrence of a body inversion, reversing the dorsoventral axis the extension of the notochord, now present along its entire length the larval stage being removed from development 1. Lamprey have an extended larval period, during which time this juvenile form is referred to as a(n) ___________________________.
6. An oil wildcatter owns drilling rights at two widely separated locations. After consulting a geologist, he feels that at each location the odds against discovering oil if a well is drilled are 9 to 1. A well costs $100,000 to drill, and this is a total loss if no oil is found. On the other hand, if oil is discovered, rights to the oil can be sold for $1,600,000. The wildcatter has $100,000 available for drilling expenses. Find the...

To practice Tactics Box 4.3 Drawing a free-body diagram. A free-body diagram is a diagram that represents the object as a particle and shows all of the forces acting on the object. Learning how to draw such a diagram is a very important skill in solving physics problems. This Tactics Box explains the essential steps to construct a correct free-body diagram.

2 (18 pts). Consider the market for oil A. Draw a market diagram for oil and make sure and label it completely. Show equilibrium price at $70 per barrel and equilibrium output at 19 million barrels per day. B. Fully explain why the market equilibrium output is efficient. C. Now, assume that burning oil creates global warming and a negative externality (social cost). Fully explain (using your diagram too) why the market equilibrium fails to allocate resources correctly. D. Recently,...
