Questions: Which of the following lists the terms from simplest to most complex cells, organs, tissues, organ systems, organism organs, organ system, organism, cells, tissues tissues, organs, organ systems, organism, cells cells, tissues, organs, organ systems, organism

The answer is the fourth one: cells, tissues, organs, organ systems, organism.

Explanation for each option:

1. Cells, organs, tissues, organ systems, organism: This order is incorrect because it places organs before tissues. Tissues are made up of cells, and organs are made up of tissues.

2. Organs, organ system, organism, cells, tissues: This order is incorrect because it starts with organs and ends with tissues, which does not follow the progression from simplest to most complex.

3. Tissues, organs, organ systems, organism, cells: This order is incorrect because it ends with cells, which are the simplest unit, not the most complex.

4. Cells, tissues, organs, organ systems, organism: This is the correct order. It starts with cells, which are the simplest unit of life, and progresses to tissues (groups of similar cells), then to organs (structures made of different tissues), followed by organ systems (groups of organs working together), and finally to the organism (a complete living entity).

In summary, the correct order from simplest to most complex is: cells, tissues, organs, organ systems, organism.
