Scientists detect their effect on the matter nearby, say if a normal star passes near a black hole, the black hole will pull it towards itself tearing it apart, as the attracted matter accelerates it emits x-rays that radiate in space till it reaches the Earth.

Mendel came up with his law of independent assortment through his investigation studying
dusya [7]
All of the answers presented above are correct.
Before Gregor Mendel's research, it was believed that parents' characteristics were passed down to the next generation were not inherited as separate units, but blended together in the next generation.
While he was studying the inheritance of different traits of the pea plant such as the height of the plant, the shape and color of the seed and the variability of the color of the flowers.
During his experiments, he noticed that the simple traits as height were passed down to the filial generation separately, so they were not blending in the next generation as it was previously thought. 
He managed to get purebred plants for certain traits by self-pollination of the pea plants and used them for this experiments.
He determined that some of the traits were expressed more often and with a higher ratio and called them dominant, as opposed to recessive traits that were expressed less often when cross-breeding with an individual with a dominant trait.

This has no relevance if you want to test whether or not you can squeeze more in a minute. You only need one set of clothespins for this. </span>
