22. ALL LIVING THINGS 5. Respond to their environment A signal to which an organism responds = ___________________ STIMULUS Image from: http://www.travel-net.com/~andrews/images/animations/traffic.gif

23. ALL LIVING THINGS 5. Respond to their environment 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.

24. ALL LIVING THINGS 5. Respond to their environment A stimulus can be ____________ Ex: When the glucose level in your bloodstream becomes low, your body responds by making you feel hungry. http://www.israellycool.com/eat%20guy%20AFP.jpg http://www.estrellamountain.edu/faculty/farabee/biobk/BioBookCHEM2.html INTERNAL

25. ALL LIVING THINGS 6. Homeostasis Keep conditions inside the cell constant = ______________________ IF temperature, water content, nutrients, acidity change too much... the cell will die. HOMEOSTASIS

26. 6. HOMEOSTASIS involves internal __________ mechanisms If body temp drops too low, “shivering” produces heat to warm you up. http://www.dreamstime.com/thumb_4/1099235658Q3A4x8.jpg http://www.clipartheaven.com/clipart/seasons_&_weather/overheating_2.gif If temp is too hot, “sweating” cools you down.
