In biology 102 lab‚ I conducted an experiment dealing with worms and how they regenerate or “grow”. We did this study over a specific type of worm called Planaria‚ which are simple‚ small‚ flat worms that reside in aquatic environments and are free-living (Brewton‚ 2017‚ p. 44). To start‚ I went over to the lab counters and obtained my worm with a plastic pipette‚ sucking up the worm with a little bit of water and placing it in a tiny covered plate. The water was essential to include with the worm

basic way: Body fluid is filtered by a special organ. Selectively permeable membranes remove urea or uric acid. Osmolarity is controlled by selective reabsorption/secretion. C 5 types of excretory systems: None in porifera‚ cnidaria Protonephridia in planaria & rotifers Metanephridia in annelids Malpighian tubules in terrestrial arthropods Kidneys (with nephrons) in vertebrates Protonephridia Have flame bulbs‚ tubules‚ and nephridopores.

Invertebrates Jellyfish The Jellyfish are truly a wonder of nature. They have always been objects of deep observation and admiration. Not to mention the fact‚ that they are also considered in great awe‚ fear and even repulsion by some folks.
