Explanation:

• Opción 1 (Models make some things easier to understand): Los modelos científicos simplifican conceptos complejos, como estructuras atómicas o ecosistemas, facilitando su comprensión.
• Opción 3 (Models help scientists visualize things they can’t see): Modelos como diagramas de ADN o modelos atómicos permiten visualizar objetos o procesos invisibles.
• Opción 5 (Scientists can analyze models to make predictions): Modelos (por ejemplo, climáticos o genéticos) se usan para simular y predecir fenómenos.

Las opciones incorrectas:

• Opción 2 (Measurements can be made only on models): Mediciones se realizan en objetos reales o fenómenos, no solo en modelos.
• Opción 4 (Models are perfectly accurate representations of objects): Los modelos son simplificaciones y nunca son perfectamente precisos.

Answer:

A. Models make some things easier to understand
C. Models help scientists visualize things they can’t see
E. Scientists can analyze models to make predictions
