Sinh học - Chapter 1: Introduction: Ten themes in the study of life

Investigating biology at its many levels is fundamental to the study of life. Biological processes often involve several levels of biological organization. The coordinated strike of a rattlesnake at a mouse requires complex interactions at the molecular, cell, tissue, and organ levels within its body. The outcome impacts not only the well-being of the snake and the mouse but also the populations of both with implications for their biological community. Many biologists study life at one level but gain a broader perspective when they integrate their discoveries with processes at other levels.
