ote: The fifth and final blank describes either feature 5, 6, or 7. 1. Living systems are organized in a hierarchy, with each level of organization having its own emergent properties. Biological evolution is an emergent property that first appears at the level of describes how it changes over time. and 2. Living organisms contain chemical instructions that govern their structure and function Life’s instructions are stored in molecules of 3. Living organisms engage in metabolic activities During , complex biological compounds are assembled from simple raw materials. 4. Energy flows and matter cycles through living systems. Matter cycles through living systems, because matter is transferred. 5. Living organisms compensate for changes in the environment. 6. Living organisms reproduce and undergo development. 7 Populations of living things change from one generation to the next. is a process that changes an individual during the course of its lifetime. Your body produces and gives off excess heat. When this ccurs, you warm up the air around yourself. As the warm air around you rises, it forms an air column that also carries eway skin flakes. In the video to the right, you can image this so-called human thermal plume using an optical specialized for viewing thermal airflow. If an individual cannot release this excess heat, the body isks damage from overheating. The mechanism for maintaining a set body temperature best illustrates which key feature of life (1-7)? 0:12/0:30 With kind permission, University Professor Gary Settles, Penn State
