Introduction The annelids (also called "ringed worms")‚ formally called Annelida (from Latin anellus "little ring")‚ are a large phylum of segmented worms‚ with over 2‚000 modern species including ragworms‚ earthworms and leeches. Annelids are abundance in freshwater‚ brackish and marine sediments. They are bilaterally symmetrical‚ triploblastic‚ coelomate organisms. These invertebrates can be recognized by their segmented bodies. Segments each contain elements of such body systems as circulatory

animal dissections and vivisection still necessary as teaching tools?” Pat Graham is against dissection and responds to Masci’s question. In his first paragraph he makes his claim by stating‚ “The burden is on those of us who oppose dissection to illustrate that alternative methods in no way lessen academic standards.” Graham argues that no schools‚ except medical schools should be allowed to use animals in labs as teaching tools. He tries to explain that using animal labs for dissection studies

Paramecium living in the intestines of termites breaks down the cellulose walls of wood fibers releasing proteins that are absorbed by the termites’ digestive system. Paramecium benefit by having an environment to thrive and they ingest the wood fibers for their own nutrition as well. 2. c. An important ecological effect

It has a well-developed digestive‚ circulatory‚ respiratory and nervous system. The size can range any where from a length of a few centimeters to a length of up to 11 feet. Earthworms can burrow under ground with considerable speed especially in loose soil. What is really interesting is the

Earthworms will be examined‚ to determine if oxygen is converted to carbon dioxide within the process. Hypothesis: The earthworm will convert oxygen to carbon dioxide. Materials: filter pump‚ sodium hydroxide solution‚ limewater‚ several insects or worms. Method: 1. Set up all the flasks in position‚ in the

During the 19th century‚ the taking of bodies also known as grave robbing was a popular act because they were the only sources of material for dissection and study. Grave Robbing was normally only performed by men for the scientific and financial benefits only. Some bodies may have been opened to try and predict the future. The supply was limited by law‚ this is why some of the early grave robbers were found to be the surgeons themselves and their students. Grave Robbing was a profession for some

Purpose: To save Fred’s life ! Background information: We have to save Fred from drowning. If we drop him in the water Fred will die. Fred has only 2 lives. We can’t stab Fred with the paperclips because if we do he will also die. We have to try to get the lifesaver which is under the cup in order to save Fred’s life & keep him from drowning. Once we put the lifesaver on Fred he will be safe but we have to be careful when we’re picking up the lifesaver and Fred with paperclips. Hypothesis:
