Arrange the following terms in order from least complex to most complex.

Question

brain

nerve cell

human organism

nerve tissue

nervous stystem

Answer 1

To arrange the terms from least complex to most complex, we can consider their hierarchical organization in biological terms:

1. Nerve cell (the simplest unit)
2. Nerve tissue (a group of nerve cells)
3. Nervous system (a network of nerve tissues, including the brain and spinal cord)
4. Brain (a major organ of the nervous system)
5. Human organism (the most complex, including all body systems)

So, the ordered list is:

1. Nerve cell
2. Nerve tissue
3. Nervous system
4. Brain
5. Human organism
