Why are all six characteristics of life required for something to be considered alive, while characteristics like "movement" are not? (2 correct answers)

• Because many living organisms don't move!

• Because the six characteristics are universally present in all living things

• Because movement is the only sign of life

• Because the six characteristics are only found in plants

Imagine you are given an unfamiliar object, such as a Mexican Jumping Bean. How could you design an experiment to test for one of the six characteristics of life?

• Observe if it can move on its own and record your findings

• Ask someone if it is alive

• Check if it is green in color

• See if it makes a sound

• Reactants: Carbon dioxide and water; Products: Oxygen, glucose, and energy (ATP)

• Reactants: Nitrogen and glucose; Products: Carbon dioxide, water, and oxygen
