Question

which characteristic of life best describes the life cycle of a frog?
○ having cells
○ using energy
○ responding to the environment
○ growing and developing

Explanation:

The life cycle of a frog involves stages from egg to tadpole to adult frog, which is about the organism increasing in size, maturing, and changing structure. "Having cells" is about the basic unit of life, not specific to life cycle. "Using energy" is about metabolic processes, not the life cycle stages. "Responding to the environment" is about reacting to stimuli, not growth/development over time. "Growing and developing" directly relates to the life cycle changes (like metamorphosis) of a frog.

Answer:

D. growing and developing (assuming the options are labeled A to D as: A. having cells, B. using energy, C. responding to the environment, D. growing and developing)
