Describe biology as a science and identify the key components of scientific inquiry
The scope of biology is vast. Biologists may study anything from the microscopic (Figure 1a) or submicroscopic view of a cell to ecosystems (Figure 1b) and the whole living planet.
Listening to the daily news, you will quickly realize how many aspects of biology are discussed every day. You may hear about E. coli (Escherichia coli) outbreaks in spinach or listeria contamination in ice cream. Or you may hear about efforts toward finding a cure for Ebola, Alzheimer’s disease, and cancer. On a global scale, many researchers are committed to finding ways to protect the planet, solve environmental issues, and reduce the effects of climate change. All of these diverse endeavors are related to different facets of the discipline of biology.
Regardless of their particular focus of study, all biologists use the same methodology as they seek new discoveries: scientific inquiry.
