VOCAB WORD
  • A cell works to keep conditions inside the cell
    constant ______________________
  • IF temperature, water content, nutrients, acidity
    change too much
  • . . . the cell will die.

  • HOMEOSTASIS involvesinternal __________
    mechanisms

If body temp drops too low, shivering produces
heat to warm you up.
If temp is too hot, sweating cools you down.
