Unit 1 Mock Test Review
Key Concepts
●Our body systems work together to maintain homeostasis. Certain things
disrupt homeostasis which make us sick.
●Homeostasis is maintained through negative feedback loops (these stop
or reverse an action). Positive feedback loops encourage an action to
continue.
●Experimental design: Control vs experimental groups, reading tables,
making/supporting/refuting claims, providing evidence and reasoning.
