Biological tests of necessity and sufficiency
Biological tests of necessity and sufficiency are tests scientists run in order to figure out how different parts of an organism's body work. They use these tests to figure out if one thing is necessary for something else to happen or if one thing is enough for something else to happen.
Imagine you want to know why a particular flower only grows in sunny spots. So, you might do a test called a necessity test which means you would try to find out if sunshine is necessary for the flower to grow. You might do experiments in different places to make sure that no matter how much water, soil, and other things are the same, the only thing that changes is the amount of sunshine. From those experiments, you would find out if without sunshine the flower doesn’t grow.
Alternatively, you might do a test called a sufficiency test which means you would try to find out if sunshine is enough for the flower to grow. You might do experiments where you vary the amount of water and soil and other things, but keep sunshine the same and see if the flower grows with just the sunshine or if something else is needed too. From those experiments, you would find out if sunshine is enough for the flower to grow.
Scientists use similar tests when studying how different parts of an organism's body work. They will use these tests to figure out if something is necessary for something else to happen or if something is enough for something else to happen. By running these tests, scientists can better understand how animals and plants work!
