Which is the relationship between photosynthesis and cellular respiration?
cellular respiration makes the glucose that is needed by photosynthesis.
photosynthesis makes the glucose that is broken down by cellular respiration
cellular respiration converts the glucose that is made by photosynthesis to oxygen.
photosynthesis converts the glucose that is made by cellular respiration to carbon dioxide.

The goal of this experiment was to answer the question, "how does diffraction occur? " suppose you formulated this alternate hypothesis: if the gap width is increased while keeping wavelength constant, then the observed diffraction will decrease because the less the ratio between wavelength and gap width is, the smaller the observed diffraction angle will be.to test this hypothesis, you would change the  gap widthdiffraction anglewavelength  and observe the  gap widthdiffraction anglewavelength  in the system.therefore, the independent variable would be the  gap widthdiffraction anglewavelength  and the dependent variable would be the  gap widthdiffraction anglewavelength.
