Cosmology: Universe :: Morphology:____

Structure

The answer is Structure.

The analogy is study of : subject. Cosmology is the study of the universe, and morphology is the study of structure. The other options do not make sense in the context of the analogy.

• Function is not the subject of cosmology, it is the purpose of something.
• Size is not the subject of cosmology, it is the measurement of something.
• Anatomy is the study of the structure of living things, not the universe.

• Cosmology is the study of the universe, including its origin, evolution, and structure.
• Morphology is the study of the form and structure of organisms.
