Answer the following question given this paragraph: As living things evolve, they generally become better suited for their environment. This is because they evolve adaptations. An adaptation is a characteristic that helps a living thing survive and reproduce in a given environment. Look at the mole in Figure below . It has tentacles around its nose that it uses to sense things by touch. The mole lives underground in the soil where it is always dark. However, by using its touch organ, it can detect even tiny food items in the soil in total darkness. The touch organ is an adaptation because it helps the mole survive in its dark, underground environment. Q: Living things evolve what characteristics that make them better suited for their environment? A:

OPTIONS:
- mutations
- instincts
- reflexes
- adaptations

Answer:
adaptations
