Mitchell created a diagram to describe the levels of organization within a multicellular organism, in order from smallest to largest.

Which mistake did Mitchell make in his diagram?

A.
Mitchell did not correctly describe tissues.

B.
Mitchell reversed the order of tissues and organs.

C.
Mitchell did not correctly describe organ systems.

D.
Mitchell reversed the order of organ systems and organisms.

D. Mitchell reversed the order of organ systems and organisms.

The correct answer is B. Mitchell reversed the order of tissues and organs.

To identify the mistake in Mitchell's diagram, let's first understand the correct order of levels of organization within a multicellular organism, from smallest to largest:

1. Cells: the basic unit of life.
2. Tissues: a group of similar cells with a common function.
3. Organs: made up of different tissues working together to perform a specific function.
4. Organ systems: a group of organs working together to carry out a particular function in the body.
5. Organisms: a complete living individual.

Now, let's go through the options provided and see which one represents the mistake in Mitchell's diagram:

A. Mitchell did not correctly describe tissues: This option suggests that Mitchell's description of tissues is incorrect. However, we don't have enough information to determine if this is the mistake.

B. Mitchell reversed the order of tissues and organs: This option states that Mitchell mistakenly placed tissues before organs. Since tissues should come before organs in the correct order, this is a potential mistake.

C. Mitchell did not correctly describe organ systems: According to this option, Mitchell's description of organ systems is incorrect. However, we don't have enough information to determine if this is the mistake.

D. Mitchell reversed the order of organ systems and organisms: This option suggests that Mitchell mistakenly placed organ systems after organisms. Since organ systems should come before organisms in the correct order, this is also a potential mistake.

Based on the analysis, the potential mistakes are option B (reversing the order of tissues and organs) and option D (reversing the order of organ systems and organisms). To identify the specific mistake, we would need to examine Mitchell's actual diagram.
