Your friend is really irritable while sitting in class. He feels lightheaded and dizzy. He is also feeling a bit of confusion and brain fog.

What inferences are most realistic to make about the biomolecules in your friend's body?

• He is running low on fast sources of energy

• Proteins are being broken down or reshaped

• The coding information in the cell is incorrect or incomplete

• There is not enough insulation or energy storage

A scientist discovers new life on a distant planet. While watching the alien species live on the planet, scientists begin to notice that in order to hunt this species will attack another smaller species and inject them with some sort of liquid. After a short time, the smaller organism develops a sort of necrosis which is when a small portion of the organism's flesh begins to break down. Soon after necrosis begins the smaller organism dies.

What can you infer about the function of the poison?

• It decreases fast sources of energy

• Proteins are being broken down or reshaped

• The coding information in the cell is altered

• If removes insulation and long term energy storage
