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 Bats are in their sleep cycle happens, how will it affect WEAKER echolocation. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - Several types of gases form in the atmosphere - May come from different sources - The gases remain trapped in the atmosphere - Through the suns light the gases hold in heat and energy - Trap them in our atmosphere - The earth may become warmer this way. Perturbation hypothesis: suppose more resources available happens, how will it affect a SMALLER greenhouse effect. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

Process: - The air is cold - Water is in the air - The water forms tiny ice crystals - The ice crystals collide with each other - The ice crystals stick to each other - The ice crystals get bigger as more of them stick together - The ice crystals get too heavy to be in the air - The ice crystals become snowflakes - The snow flakes fall to the ground as snow. Perturbation hypothesis: suppose less ice crystals collide with each other happens, how will it affect LESS snow. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - Prophase is the first and longest stage of mitosis - In this stage the chromosomes become visible and the centrioles separate and move to opposite poles of the cell - In prophase the chromosomes become visible and the centrioles separate and move to opposite poles of the cell - In metaphase the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere - In anaphase the sister chromatids separate into individual chromosomes and are pulled apart - During telophase the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes - Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear. Perturbation hypothesis: suppose less nucleus happens, how will it affect HURTING mitosis to proceed normally. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes
