Are viruses alive? This question is debated among scientists throughout the world. Consider the following passage. Scientific re

searchers discovered agents that behaved like bacteria causing diseases such as rabies and hoof-and-mouth, but were much smaller. At this time it became the general view that viruses were biologically "alive." This perception changed in 1935 when the tobacco mosaic virus was crystallized and scientists demonstrated that the particles lacked any mechanisms necessary for metabolic function. It was determined that viruses consisted of a nucleic acid, DNA or RNA, surrounded by a protein shell and the scientific view changed: viruses are complex biochemical mechanisms but not alive. According to the passage, the MOST IMPORTANT evidence supporting the opinion that viruses are not alive is that they A) cause disease. B) contain DNA or RNA. C) are much smaller than bacteria. D) do not have a cellular structure.

Answer:

Try this.

Explanation:

       I'm not too sure because the teacher never gave me enough information (Need Bigger Graph). Get bigger graph paper as it says "The X-axis should be years and the Y-axis should be coal production." On the X-axis (Horizontal Line) write "Years" and on the Y-Axis (Vertical Line) write "Coal Production."

Now, your gonna start listing all the years on the X-Axis 1996 through 2011, And on the Y-Axis list all the coal productions 145 and all the numbers through 634. Make sure you have the regions, Appalachian, Interior and Western.

     I'm sorry if this didn't help, this is what I did and it helped me, I thought it might help you too.
