Characteristics of ALL LIVING THINGS ______________________________ _____________________________

1) All living things Respire Living cells release ___________ from _____________ molecules. The form of _______________ that releases the most energy use __________. Many multicellular organisms have _____ _____________ systems to supply thir cells with oxygen from their environment

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

2) ALL LIVING THINGS Respond to their environment  Image from: http://www.ccs.k12.in.us/chsBS/kons/kons/images/stimresp.jpg 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. http://www.nofretete-page.de/gemischtNeu/TN_plant_grow_w.JPG

2) ALL LIVING THINGS Respond to their environment   http://www.estrellamountain.edu/faculty/farabee/biobk/BioBookCHEM2.html 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

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

HOMEOSTASIS Drinking a BIG GULP increases the amount of water in your body http://www.me-go.net/rtw/images/biggulp.jpg Your next stop gets rid of the excess water. (OSMOREGULATION) http://pluck.typepad.com/photos/uncategorized/restroom_blog.gif
