Problem: Process: - You breathe in - Air goes through all the little branches in your lungs to fill up the air sacs, or alveoli - Oxygen goes through the walls of the alveoli and into the capillaries - The oxygen goes into the bloodstream - Oxygen is left and carbon dioxide is picked up - You breathe it out through your lungs - Perturbation hypothesis: suppose volcano erupts less strongly happens, how will it affect less oxygen can go into the bloodstream. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no

Problem: Process: - Mix pancake mix with water - Heat a griddle - Pour a circle of batter in the griddle - When most of the bubbles pop on the surface, flip - Cook to desired color - Apply butter, syrup and enjoy - Perturbation hypothesis: suppose harder force of particles against rock happens, how will it affect Pancakes are smaller. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no

Problem: Process: - The organism must die to begin the process - The soft tissue decomposes - The bones are left behind - Scavengers tear the body apart and move the bones elsewhere - Wind and rain also scatter the bones further - The bones left behind will weather and become buried by sand and soil - The proteins in the bone are replaced with minerals that are dissolved in the soil - This creates a rock-like substance called a fossil - Water and wind erosion wear away the layers of soil on top of the fossil - This makes discovery of the fossil possible. Perturbation hypothesis: suppose there is more drought in the area happens, how will it affect pushes the bones more down into the ground. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: Process: - Chemicals like sulfur dioxide and nitrogen are released into the air - These substances rise into the high atmosphere - They react with water and oxygen - This creates a more acidic rain - The rain with the high acid content falls. Perturbation hypothesis: suppose more acidic rain created happens, how will it affect MORE damage by acid rain. Does the supposed perturbation have an effect (direct or indirect) on the process?

A:
yes
