Chapter Content: Major Themes in Biology

Complete the following questions as you read the first chapter content—Major Themes in Biology:

1. The branched structure of human lungs significantly increases the surface area for gas exchange. This greatly increases the efficiency of gas exchange within the lungs. Which of the following unifying themes of biology does this example illustrate?

A) Evolution

B) Relationship to structure and function

C) Interaction within biological systems

D) Information flow

2. Human growth hormone (HGH) is necessary for growth during human adolescence. Pituitary dwarfism is a condition that results from the inability of a person to produce HGH. Luckily, the human gene for HGH can be inserted into E. coli bacteria, which are able to make our HGH. The resulting HGH is used by people who are unable to make their own. What prop- erty about hereditary information makes this possible?

1. A scientist at the University of Iowa uses a microscope to observe cells in the brain known as microglia. He makes observations about their structure, location, and activity. The scientist eventually observes the cells undergo a sudden and radical shift in their structure/shape and their motility (ability to move). He asks himself questions about what is causing this shift in behaviors and begins to design an experiment to determine the answer. Briefly describe how the scientist practiced both the exploration and testing aspects of scientific inquiry.
