Question

which of the following is not a characteristic of all living things?

• made of cells
• making up atoms and molecules
• sensitivity to the environment

Explanation:

To determine which is not a characteristic of all living things, we analyze each option:

1. Made of cells: All living organisms are composed of one or more cells (cell theory), so this is a universal characteristic.
2. Making up atoms and molecules: Atoms and molecules are the building blocks of matter, including non - living matter. Living things are made of cells, which are composed of atoms and molecules, but "making up atoms and molecules" is not a defining characteristic of living things (as non - living things also consist of atoms and molecules).
3. Sensitivity to the environment: All living things respond to stimuli in their environment, so this is a universal characteristic.

Answer:

Making up atoms and molecules
