Answer to Question 1

D

Answer to Question 2

When Jake steps on a piece of ice it will activate a thermoreceptor which are free nerve endings in the dermis. This sensation will travel up the axon of a first-order neuron entering the CNS through the dorsal root. The first-order neuron will synapse with a second-order (interneuron) in the posterior gray horn. The second-order axons will enter the lateral spinothalamic tract on the opposite side of the spinal cord and ascend to the thalamus. At the thalamus the second-order neuron will synapse with a third-order neuron which will end at the primary sensory cortex on the left side of the brain.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
