To determine:
The essential elements basic to all living things.
Introduction:
All living things require some basic elements. Without these essential elements, life would not exist.
Explanation of Solution
There are six basic or main elements that are required for life and they are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. These elements are responsible for important functions of living things. For example, phosphorus is present in the form of phospholipids which is one of the major components of cell membranes. It forms a lipid bilayer that keeps ions, proteins and some other molecules inside the cell membrane. In these six elements carbon, nitrogen, oxygen, and hydrogen make up about 96% of the human body.
A living cell is made up of 59% hydrogen, 24% oxygen, 11% carbon, 4% nitrogen, and 2% phosphorus, and sulfur.

We will use a different type of graph to derive additional information from the CO2 data (Fig A1.6.2) 1. Calculate the average rate of increase in COz concentration per year for the time intervals 1959-1969, 1969- 1979, etc. and write the results in the spaces provided. The value for 1959-1969 is provided for you as an example. 2. Plot the results as a bar graph. The 1959-1969 is plotted for you. 3.

- 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?
