Could you please put in order the following experiment (erase the ones that are not needed):  1) A total of 8 bags will be made, Bags 1-4 will be the control group and 5-8 will be the test group. 2) Put 1 unripe pear in each of the control bags. Seal each bag and one unripe pear and 1 banana in each of the test bags and seal them.  3)Place all the bags together and record the observations from the initial appearance to the final appearance of the fruit each day. 4)After a few days the ripening status of them is tested by staining them with the iodine solution. 5) After preparing the iodine solution, pour the iodine stain into a shallow tray and dip it with a half-cut pear. 6) Allow the fruit to absorb the stain and remove and rinse it with water. 7) Repeat the step by adding more stain as needed to observe the ripening status.

Prokaryotic evolution

The term evolution means the gradual change or a transformation from a simple or primitive state to a complex or advanced state. Prokaryotic evolution is a concept that involves the evolution of the form and function of most primitive organisms (prokaryotes) through several stages and changes to form diverse life as a part of organic evolution.
