In 1668, Francesco Redi, an Italian scientist, conducted an experiment with jars of meat. This experiment was noteworthy because it disapproved the hypothesis of spontaneous generation.
He placed fresh meat in each of two separate jars. One of the jars was left open and the other was covered with a cloth. A few days later, the open jar contained maggots while the covered jar contained no maggots, although there were maggots on the exterior surface of the cloth covering the jar.
Coastal mountains force cool, moist air from oceans to rise as it moves toward land. Clouds form, and precipitation falls on the <u>windward</u> side of the mountain. On the <u>leeward</u> side of the mountain, very little precipitation falls.

During prophase, the parent cell chromosomes — which were duplicated during S phase — condense and become thousands of times more compact than they were during interphase. ... Cohesin forms rings that hold the sister chromatids together, whereas condensin forms rings that coil the chromosomes into highly compact forms.
