Afterlife and Soul As late asthe editorial staff of the Syntopicon found in their compilation of the Great Books of the Western Worldthat "The philosophical issue concerning immortality cannot be separated from issues concerning the existence and nature of man's soul. Ancient Greek religion[ edit ] Immortality in ancient Greek religion originally always included an eternal union of body and soul as can be seen in HomerHesiodand various other ancient texts. The soul was considered to have an eternal existence in Hades, but without the body the soul was considered dead. Although almost everybody had nothing to look forward to but an eternal existence as a disembodied dead soul, a number of men and women were considered to have gained physical immortality and been brought to live forever in either Elysiumthe Islands of the Blessedheaven, the ocean or literally right under the ground.
Hire Writer Place one planarian in each of the three dishes labeled with the original name with a paintbrush 9. Carefully slice the planarians in half with a knife Use a paintbrush to move one half of the planarian into the matching named Petri dish Clean the water of the original dishes and refill with clean water All planarians should be in clean water Feed all planarians with a tiny bit of boiled eggs Measure the length of all half planarians and record Test the reaction of the flashlight test on the planarians and record Chubs split in two after the first day but Chubs 1 died so we moved the second half of Chubs into a Petri dish and labeled him Chubs 1.
The longest over all Carol was actually the first worm to die completely by day four, including both parts.
The worms that were mm long lasted the longest Delia and Chubs 1. On day five Delia was actually transparent on the half that she was growing back.
It was interesting that Chubs split in half on day two, while the other part of him had died. Delia was the last survivor and almost the shortest worm, living till day six.
All the planarians reacted to the light the first day by moving closer to it, but after they were cut, none of the worms reacted at all. Conclusion It is important that we study such animals because more than half of planarian genes have parallels in people, and some of their basic physiological systems operate like ours.
This could lead scientist into understanding how to regenerate human tissues or cells. If scientist learn how to achieve this than many different lath issues could be solved, for instances diabetes. This could also help scientist discover how to mutate the cells in other animals so they regenerate when they lose body ligaments in the wild.
This could result in less deaths of animals and a lower extinction rate. Scientist do not study on humans because of their inability to grow back but one day hope to achieve this goal. The soft- bodied planarians move in a similar fashion as a slug.
They use their foot to slither through a trail of slime, leaving most of the slime behind. The planarian extends a tube-like pharynx from its mouth to reach for food. Through this tube it secretes digestive juice onto its prey. The food is partially digested externally before it is sucked into the Castro vascular cavity where it is digested the rest of the way, and then diffused to the rest of the body.
Without the pharynx, the digestive juice would not reach the food and it would not be able to ingest anything, which would lead to starvation.
The pharynx is a specialized organ that allows the planarian to find and take in food. Our worms were all cut the same way, but gave very different results. The longest planarian parts died a lot quicker than the shorter pieces of worm. Concluding that our hypothesis had not turned out how we had expected based on our data results.
A probable reason for the death of some of our worms could have been overfeeding them. Sometimes the chunks of egg was hard to get off, so we added more but then it all came out. Chubs 1 was over whelmed with food the first day, so he could have over eaten and died.
Through performing this experiment, learned many things about how regeneration works. I was amazed to see the planarians moving after they had been cut into two pieces. I also enjoyed seeing how quickly the worms grew and regeneration does not take very long. I enjoyed his lab because it was very fascinating to see understand how a scientist could use regeneration to fix problems in the human.

Study on Bilinear Scheme and Application to Three-dimensional Convective Equation (Itaru Hataue and Yosuke Matsuda). On the fifth day the planarian was observed the planarian head grew another mill meter and the planarian tail grew 1 millimeter.
The last day the planarian was observed the planarian head was the same length at 6 millimeters and the planarian tail was missing.
