Match the following terms and definitions. 1. a degree of organism complexity; either unicellular or colonial negative feedback 2. the relatively constant state in the internal environment of an organism positive feedback 3. self-regulation mechanisms that send information to appropriate physiological systems so that appropriate adjustments can be made homeostasis 4. a control mechanism that inhibits or counteracts an earlier reaction cellular level 5. a control mechanism that intensifies or enhances an earlier reaction system level 6. a degree of organism complexity; cells arranged into systems feedback loops

1. Cellular level refers to a degree of organism complexity, which is either colonial or unicellular.  

2. Homeostasis refers to the comparatively steady state in the internal environment of an organism.  

3. Feedback loops are the self-regulation approaches, which transmit information to a suitable physiological system so that appropriate amendments can be done.  

4. Negative feedback refers to a control mechanism, which counteracts or prevents the previous reaction.  

5. Positive feedback refers to a control mechanism, which enhances or augments the previous reaction.  

6. System-level refers to the extent of the complexity of an organism, that is, the cells organized into systems.  

carbohydrates are the body's preferred source of energy.
