Q: Process: - Muscles work by expanding and contracting - A muscle fiber gets a signal from its nerve - Proteins and chemicals release energy to either contract the muscle or relax it - When the muscles contracts the bones connected to he muscle are pulled closer together - When the muscle relaxes the bones move farther apart. Perturbation hypothesis: suppose more bacteria to reproduce happens, how will it affect muscles contracting MORE INTENSELY. Does the supposed perturbation have an effect (direct or indirect) on the process?
A: no

Q: Process: - You plant vegetable seeds in the ground - You water the seeds - You wait for the seeds to sprout - You keep the area free of pests and weeds while the plants grow - You thin out the plants as they get bigger to give them space to grow - You remove the vegetables from the plants when they are ripe. Perturbation hypothesis: suppose more vegetables grown happens, how will it affect LESS vegetables. Does the supposed perturbation have an effect (direct or indirect) on the process?
A: yes

Q: Process: - Bread is exposed to the elements - Bread absorbs water from the air - Bread absorbs warmth from the air - Dust particles with mold spores fall on bread - Mold spores start to consume the bread for energy - Mold colonies grow until they are visible. Perturbation hypothesis: suppose Christmas dinner time happens, how will it affect bread is kept somewhere more moist than usual. Does the supposed perturbation have an effect (direct or indirect) on the process?
A: no

Q: Process: - People breathe and expel carbon dioxide - Engines produce carbon dioxide - Living things produce waste - Waste decomposes - Decomposition produces methane - Water evaporates - Water vapor joins the atmosphere - Carbon dioxide, water vapor and methane are greenhouse gases - Perturbation hypothesis: suppose oil is found in other than Middle Eastern countries happens, how will it affect MORE greenhouse gases. Does the supposed perturbation have an effect (direct or indirect) on the process?
A:
yes
