science Flashcards
passive transport
movement of water/particles from high to low concentration
diffusion
movement of particles from high to low concentration
equilibrium
when the solute concentrations are the same inside and outside of the cell
Osmosis
movement of water from hight to low
how does negative feedback maintain homeostasis?
It helps the body maintain balanced levels, As a stimulus drops too low, it will increase that stimulus
stimulus
something in the environment that causes a change
active transport
movement of water/particles from low to high concentration
facilitated diffusion
When specific substances move through transport or carrier proteins high to low
negative feedback
receptors detect a change and initiate a response that will counter that change
response
action of an organism as a result of the stimulus
What is the function of feedback loops
gives information to the brain
