AP Bio Systems-Chapter Part 3 Flashcards
Homeostasis
The internal “steady state” condition needed to stay alive.
What do systems provide (their purpose)
Homeostasis
What dies the nervous system monitor and effect
Conditions and effects responses that maintain homeostasis through the functions of organ systems
What are the physiological processes at work in any organism constrained by
The environment, and adapted by evolution
What are the 3 examples of ways physiological processes work
Materials exchange
Energy considerations
Convergence
Materials exchange
Unicellular and microscopic organisms are able to exchange materials directly with their environment
Plants and animals have evolved adaptations to accomplish these exchanges internally (usually through maximizing surface area)
Energy considerations
The energetic considerations of an organism’s environment have consequences for physiology and behavior
Convergence
Similar environmental constraints often result in similar adaptive solutions
