In this situation, muscle cells ferment glucose to two molecules of lactic acid — again, with the net production of only two molecules of ATP per glucose molecule (Figure 16-6, left).
        
             
        
        
        
Answer: A scenario often presented to introductory physics classes is that of a "gravity tunnel" — a tube drilled from one side of the Earth to the other through the planet's center. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds.
Explanation: However, solar and lunar gravity, which also perturb orbiting satellites, would eventually pull you into the tunnel wall anyway [source: Darling ]. Strike a chord: Fun fact: A straight line from any point to any other point through the planet would take the same amount of time to fall through like a tunnel through Earth's center.
 
        
             
        
        
        
Answer:
The population first grows, stabilizes, and then declines.
Explanation:
A researcher is studying a population with a unique age structure. An age structured histogram he has developed over the course of several decades has undergone transformations in shape, from a pyramid shape to a roughly rectangular shape to an inverted pyramid shape (where the base is narrower than the top). The population first grows, stabilizes, and then declines.
