Problem: Process: - The bat sends out sound waves from their mouth or nose - The sound waves hit an object - Echoes are produced - The echo returns to the bat's ears - The bat hears the echo - The bat can figure out where the object is located. Perturbation hypothesis: suppose if more bats are asleep happens, how will it affect More echo will be produced. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: Process: - A person takes in oxygen through their nose or mouth - The oxygen travels into the body - Breaks down into glucose - Carbon dioxide is produced by the glucose breakdown - The carbon dioxide is exhaled out of the body through the nose or mouth. Perturbation hypothesis: suppose less oxygen travels in the body happens, how will it affect glucose is produced more. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: Process: - Green is a color that gathers sunlight easily - Sunlight is gathered by the leaves of the plant - The sunlight is broken down into glucose through photosynthesis - The glucose travels the plant - The plant uses that glucose as energy to grow. Perturbation hypothesis: suppose the sunlight is blocked because of trees happens, how will it affect If more sunlight is gathered by the plant. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: Process: - Magma rises through cracks in the Earth's crust - The pressure causes plates to move - Magma explodes to the surface - The lava from the eruption cools to form new crust - After several eruptions, the rock builds up and a volcano forms - Perturbation hypothesis: suppose there is less pressure happens, how will it affect there is less new crust that forms. Does the supposed perturbation have an effect (direct or indirect) on the process?

A:
yes
