1. which characteristic of life is shown in the image below?

a. maintain homeostasis
b. display organization
c. respond to stimuli
d. made of one or more cells
e. both a and c are correct

Explanation:

• Question 5: Volcanoes release gases (e.g., sulfur dioxide) into the atmosphere, alter landforms (geosphere), can harm or destroy living organisms (biosphere), and affect water bodies (hydrosphere). So all these spheres are affected.
• Question 6: Many living things (e.g., bacteria, plants) do not have a brain. But all living things display organization (cells - tissues - organs etc. in multicellular; internal organization in unicellular), are made of cells, grow/develop, and maintain homeostasis.
• Question 7: The image shows a feedback loop in response to a stimulus (like body responding to heat/cold). Homeostasis is maintained through responses to stimuli (e.g., sweating when hot - response to heat stimulus).

Answer:

1. E. All of these
2. D. have a brain
3. E. Both a and c are correct
