Characteristics of Life

Which is NOT a characteristic of life?

• adaptation

• breathing

• homeostasis

• reproduction

Which of these is a characteristic of ALL living things?

• respond to external stimuli

• absorb complex food molecules

• produce offspring by means of sexual reproduction

• use energy to actively move through the environment

A Basilisk lizard like the one shown is a reptile. Reptiles often modify their behavior in order to help control body temperature. When their body temperature is low, reptiles often bask in the sun. When their body temperature is too high, they will often hide in shady and cool places.

When reptiles alter their behavior in order to help control their body temperature, what characteristic of living organisms is being shown?

• Living things grow and develop.

• All living organisms are made of cells.

• Populations of living things evolve over time.

• Living organisms respond to stimuli.
