Problem: Given the question: 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 if during anaphase sister chromatids split up happens, how will it affect the process of mitosis will decrease.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++++++++++++++++++++++++++
The answer is:
yes


Problem: Given the question: Process:  - Water gets into cracks in rocks - The water freezes into ice - The cracks expand - Over time the rocks split - The rocks are now in smaller pieces.  Perturbation hypothesis: suppose it is warmer than previously happens, how will it affect LESS or SLOWER weathering occurring.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++++++++++++++++++++++++++
The answer is:
yes


Problem: Given the question: Process:  - A man and woman mate - Embryo is C - Embryo grows and develops into a fetus inside the woman&#x27;s womb - The fetus is born - Begins to grow and develop through infancy and childhood - In the teenage years the human experiences puberty - Reaches sexual maturity - At 18 the human becomes an adult - Adult may procreate continuing the cycle.  Perturbation hypothesis: suppose men and women are segregated happens, how will it affect fewer women and men mate.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++++++++++++++++++++++++++
The answer is:

yes
