A stimulus can be
Ex: When there is enough water
and ground is warm enough,
seed germinates. Roots respond to
gravity & grow downward.Leaves respond to sunlight & grow up.
A stimulus can be
Ex: When the glucose level in your bloodstream becomes low, your body responds by making you feel hungry.
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,
heat to warm you up.
If temp is too hot, “sweating” cools you down.
Drinking a BIG GULP
increases the amount
of water in your body
Your next stop gets rid of the excess water.
