Question

multiple choice 2 points
which characteristic of life is best illustrated by the energy allocation changes across different life stages?
organization
adaptation
response to stimuli
metabolism

Explanation:

• Organization: Refers to the hierarchical structure of living things (cells - tissues - organs - etc.), not related to energy allocation changes.
• Adaptation: Involves traits that help an organism survive in its environment. The energy re - allocation across life stages (e.g., more energy for growth in calves, more for lactation in lactating cows) is an adaptation. Calves need to grow, so more energy is allocated to growth; lactating cows need to produce milk, so energy is re - directed.
• Response to stimuli: Is about how an organism reacts to external or internal changes (e.g., a plant growing towards light). Not relevant here.
• Metabolism: Is the set of chemical reactions in an organism. While energy is related to metabolism, the key here is the change in energy allocation for different life - stage needs (which is an adaptation), not just the general concept of metabolism.

Answer:

Adaptation
