How does a lion show "Metabolism"?
They drink water and eat animals, which they then digest and turn into energy
What does the Atomic Mass of an element tell you?
# of protons + # of neutrons
If you were hot, how would your body react to maintain homeostasis?
What is metabolism?
All the chemical reactions and processes that happen within the body/cells
A fungus releases spores into the wind. Those spores land somewhere else and become their own mushrooms.
What COL is this?
Reproduction
Use a periodic table to find the number of neutrons in an atom of Boron (B).
10.8 rounds to 11, so...
11 atomic mass - 5 protons = 6 neutrons
Provide two ways your body needs to maintain homeostasis when you play football.

Use you periodic table to help you figure out how many Hydrogens (H) can bond to one Carbon (C)
AND ALSO how any Oxygens (O) can bind to one Carbon (C).
4H to 1C
2O to 1C
Because Carbon can make 4 bonds, Hydrogen can make 1 bond each, and Oxygen can make 2 bonds each.

You must also briefly explain what each one means.
Growth/Development- get bigger and change throughout lifetime
Order- organism is organized and made of cells
Reproduction- Organism makes offspring
Homeostasis- regulation of internal environment (maintaining your normal)
Metabolism- making/using energy and getting food
Response to stimuli- when things happen to/around the organism, it responds or reacts
Evolutionary- Slow change in species over time
Magnesium (Mg) make an bond with 2 Chlorines (Cl), and it comes out to be [Mg]+2 [Cl]-2.
Is this bond ionic or covalent?
AND how many VALENCE electrons does [Mg]+2 have?
Ionic
8 VALENCE electrons because it lost its 2 valence electrons leaving it with the full shell underneath.
Which organ is most responsible for sensing and regulating the body's internal states, such as temperature and water?
