Essay Questions
 

46. Explain why a student of biology needs to study the hierarchy of levels of organization within and among living things. 

All living things are made up of chemicals. An understanding of chemistry is the foundation for understanding how living things function. All living things are made up of cells. An understanding of cell function is necessary to understand how tissues work, and how it is possible for tissues to be organized into organs. Understanding the needs of individual organisms helps the student determine the workings of populations and communities.

 

47. Many people think the term "theory" means someone's idea about something. Explain the scientific use of the term "theory", especially as it relates to the biological concept of evolution. 



A theory in biology is a collection of related hypotheses that have been repeatedly tested and have stood the test of time. The theory of evolution means that substantial evidence has been found to verify the notion that evolution has and is occurring among living organisms on earth.

 

48. Explain the relationship between ozone depletion and rising incidence of skin cancer. 



The layer of ozone surrounding the earth shields us from the sun's harmful ultraviolet rays. The UV rays are mutagenic, triggering changes in the DNA of our skin cells, giving rise to cancer. With less ozone, more UV rays hit the earth. If we continue to sunbathe and expose our skin, cancer rates will continue climbing.

 

49. Why is the study of biology central to the understanding and solving of the world's great environmental problems? 



When people do not have knowledge of biology, they do not understand the needs of organisms or the interactions that occur within ecosystems. Without an understanding of the basics of biology, people cannot hope to understand and solve the world's environmental problems.

 

50. Why is it impossible for supernatural, religious, and unexplained phenomena to be explained by biology? 



Biology, and all sciences, are based on the scientific process, which cannot be applied to supernatural, religious, and unexplained phenomena. Science examines and tests evidence; these areas have no tangible evidence for testing.
