Question: Answer the following question given this paragraph: We can see rainbows because they are formed by visible light. Visible light includes all the wavelengths of light that the human eye can detect. It allows us to see objects in the world around us. Without visible light, we would only be able to sense most objects by sound or touch, and we would never see rainbows. Like humans, most other organisms also depend on visible light, either directly or indirectly. Many animals use it to see. All plants use it to make food in the process of photosynthesis. Without the food made by plants, most other organisms could not survive. Q: What helps us see rainbows in the sky? Choices: - spectral light - myopia - prism - visible light A:

Answer the following question given this paragraph: The Gaia hypothesis states that the biosphere is its own living organism. The hypothesis suggests that the Earth is self-regulating and tends to achieve a stable state, known as homeostasis . For example the composition of our atmosphere stays fairly consistent, providing the ideal conditions for life. When carbon dioxide levels increase in the atmosphere, plants grow more quickly. As their growth continues, they remove more carbon dioxide from the atmosphere. In this way, the amount of carbon dioxide stays fairly constant without human intervention. Q: What is the hypothesis that states that the biosphere is its own living organism? Choices: - Big Bang theory - Geiger theory - Pascal's hypothesis - gaia hypothesis A:
**Answer**
gaia hypothesis
