Some ancient objects have been well-preserved in high mountain ranges,
where the concentration of oxygen is low. Otzi the Iceman lived more than
5,000 years ago. Archaeologists found him with his leather pouch, clothes,
and tools perfectly preserved in the ice of the Alps.
Marie's mother lost a leather purse in the yard of their house in Florida, where
the air has more oxygen. Marie found it 30 years later under a tree. It was
rotted and decayed.
Review the information in the data table. What does this information tell you
about the rate of decay reactions relative to the concentration of oxygen?

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
