Chapter 49, Problem 1ITD
Summary Introduction
To review:
Cities where the researchers have recorded the lowest and highest sperm counts and the cities where samples reveal the lowest and highest sperm motility (ability to move).
Introduction:
Sperm count is the number of spermatozoa or sperms present per ejaculation. The semen quality is dependent upon the number of sperms present along with the shape and the motility of the sperms. The sperm count is affected by many factors. Presence of fat affects the sperm count. People with low sperm count may get diabetes, heart stroke, and other problems.

San Andreas Transform Boundary Plate Motion
The geologic map below of southern California shows the position of the famous San Andreas Fault, a transform plate boundary between the North American Plate (east side) and the Pacific Plate (west side). The relative motion between the plates is indicated by the half arrows along the transform plate boundary (i.e., the Pacific Plate is moving to the northwest relative to the North American Plate).
Note the two bodies of Oligocene volcanic rocks (labeled Ov) on the map in the previous page located along either side of the San Andreas Fault. These rocks are about 23.5 million years old and were once one body of rock. They have been separated by displacement along the fault.
21. Based on the offset of these volcanic rocks, what is the average annual rate of relative plate motion in cm/yr?

Drug X was developed to reduce blurred vision in healthy patients, but the effectiveness had not been tested on those suffering from multiple sclerosis. A study was conducted to determine if Drug X is effective at reducing blurry vision in multiple sclerosis patients. To be considered effective, a drug must reduce blurred vision by more than 30% in patients. Researchers predicted that a 20 mg dose of the drug would be effective for treating blurred vision in multiple sclerosis patients by reducing blurred vision by more than 30%. Drug X was administered to groups of multiple sclerosis patients at three doses (10 mg/day, 20 mg/day, 30 mg/day) for three weeks. A fourth group of patients was given a placebo containing no drug X for the same length of time. Vision clarity was measured for each patient before and after the three-week period using a standard vision test. The results were analyzed and graphed (See Figure…arrow_forward
