Question: Process: - Stars burn mass - The star burns until it runs out of fuel - The star can no longer support its weight - The layers of hydrogen press down on the core - The core gets smaller and smaller under the pressure - The pressure causes gravity to get stronger - The gravity becomes so powerful that nothing can escape it - Anything that gets close to it, is drawn into it by its gravity - Light is drawn into it - Light can not escape - Perturbation hypothesis: suppose core does not get too small happens, how will it affect pressure causes gravity to get more strong. Does the supposed perturbation have an effect (direct or indirect) on the process?
Answer: yes

Question: Process: - A bird lays an egg - The egg hatches into a baby bird - Baby bird eats - Grows into an adult bird - The bird finds a mate - The pair build a nest - The birds lay eggs. Perturbation hypothesis: suppose More sunlight is provided to the plants happens, how will it affect more eggs are laid. Does the supposed perturbation have an effect (direct or indirect) on the process?
Answer: no

Question: Process: - The gravity of the sun pulls its mass inward - There is a lot of pressure on the Sun - The pressure forces atoms of hydrogen to fuse together in nuclear reactions - The energy from the reactions gives off different kinds of light - The light travels to the Earth. Perturbation hypothesis: suppose pressure stays low on the Sun happens, how will it affect LESS sunlight arriving at the Earth. Does the supposed perturbation have an effect (direct or indirect) on the process?
Answer:
yes
