(II) The roller-coaster car shown in Fig. 6-41 is dragged up to point 1 where it is released from rest. Assuming no friction, calculate the speed at points 2, 3, and 4. Figure 6-41

Campbell Biology in Focus - Standalone book 1
A recent revival of the antievolutionary intelligent design argument holds that biochemical pathways are too complex to have evolved, because all intermediate steps in a given pathway must be present to produce the final product. Critique this argument. How could you use the diversity of metabolic pa

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
