Earthworm Research Paper

People can communicate in many different ways, verbal (talking), Written (email, memo, posters), body language/gestures (the way they react when been given information), their facial expression, eye contact, sigh language and behavior. People communicate to one another on a day to day basis. People may communicate to each other for different reasons such as: Creating a relationship, keeping a stable relationship, 'chit chat', giving/receiving information or expressing ideas, thoughts or concerns.

6. Continue cutting the skin of the earthworm towards the anterior end. It is best to use an upward-pointing direction with the scissors. As you cut the skin, pin back the skin to expose the gut.

Migita and Moriyama (2004) declare that in unknown environments, animal behaves inappropriately by expressing their innate or learned behavioral patterns. A. vulgare are often found constantly moving around the edge of the Petri dish because the environment is unfamiliar and appears as an obstacle (Migita and Moriyama 2004). One observation of pill bug’s movement is when they follow each other. Males can detect females through distance chemical communication (Beauché and Richard 2013). Due to aggregation pheromone, the A. vulgare are attracted to each other.

If mealworms are attracted to moisture, and tend to move away from hardened food, why would the mealworm move towards bran flakes and begin to go inside the pile.

People communicate for many reasons, but I guess the main reasons are to get what we want, to refuse things we don’t, to give information or to find information and importantly to interact socially. We communicate to show pain, to show our emotions and express our feelings. We can communicate through speaking, touching, facial expressions and body movements. Through communication we build relationships.

A person communicate different variety of ways, both verbally and non-verbally. Primates and other animals have been communicating without the use of language since long before humans invented verbal communication. Some scientists believe that even today, most communication between humans is non-verbal. Both types of communication differ significantly between genders and across cultures.

Heartworm disease is a serious and potentially deadly disease that ultimately affects animals all around the world. A heartworm is a blood-borne parasite called Dirofilaria immitis that resides in the heart and surrounding large blood vessels of infected animals. The presence of heartworms in the body often leads to severe lung disease, heart failure, and damage to other organs. Heartworm disease affects a variety of species including pets, wildlife, and although rare, humans.

Just last month, a deadly worm was found in not one, but four locations in the U.S. state of Florida. This worm, until recently, was documented in only twenty-one countries, most of which were island nations. Although the New Guinea Flatworm may seem as a highly dangerous predator, it is only about two inches in length and mainly targets snails for its nutrition. These worms are not harmful to humans, but they will feast on any soft creature in the soil. In order to eat snails or any critters with a hard shell, the New Guinea Flatworm latches itself onto the shell’s opening and then spits out its own stomach through the opening in its belly. This allows an acidic goo to dissolve the snail’s flesh and the worm can continue on with its meal by swallowing both its stomach and the snail.

species group. The location of this earthworm was in Australia, where they claimed their habitat

When society thinks about crayfish and earthworms they become extremely curious about how their bodies operate because of how they are made up. I will give a brief synopsis of both animals before going into major detail about them. According to the online website named dictionary.com, it says that an earthworm is a burrowing annelid worm that lives in the soil. Earthworms play an important role in aerating and draining the soil and in burying organic matter (Dictionary). Crayfish are nocturnal freshwater crustacean that resembles a small lobster and inhabits in streams and rivers (Dictionary). Crayfish and earthworms are some very interesting animals that possess some exclusive qualities both similar and different.

This worm has other things it can eat as well. The one thing this worm loves to eat is the snail eggs it finds when it attaches itself to the bottom of the cabbage leaves and when it is searching for it's prey as well. Many scientists have said that the new guinea flatworm is one of the fifteen tenth largest dangerous and threatening invasion on the united states. They say it continues to grow even this year as well. It fact many people say that when it starts to develop the worms never stop growing and developing and continue to grow and grow and take over populations and specific areas in the united states. Many relationships with other species in the worm occur because the worm continues to invade state by state ,county by county or even area by area and it is causing problems everywhere. Another reason the specific species relationships happen is because the worms continue to have offspring and then they will continue to develop and develop. The next reason is the flatworm can carry a parasitic disease that infects rats and can be passed on to

1.) My hypothesis that the insects would be most repelled by the lemon plant extract was not supported. Our key findings in the experiment do not support my hypothesis because the lemon had a 60% repulsion response and was the second most repulsive behind orange with a 70% repulsion response. Although the Earthworms were repelled by the lemon plant extract, they were more so repelled by the orange plant extract. 2.)

This allowed us to perform an experiment to test which cellular components of the roundworm were able to detect and react to odors. Utilizing RNA interference, we can knock out or reduce specific gene functions by having the worms consume bacterial food that contained dsRNA. After consumption and reproduction, the construct of RNAi in the presence of the cultivated progeny were observed and determined which gene can be expressed or reduced in chemotaxis. We performed chemotaxis by creating an attractant gradient to a specific point and then observed the accumulation to the chemical signal (Bargmann,

For as long as time can be accounted for, people, as well as animals have been known to interact with each other through various methods of communication. Communication is simply the exchange of receiving and sending information from one subject to another. The word information though covers so much. People are able to display ideas, feelings, needs and desires through communication as information to another subject.

Flatworms can be free living or parasitic. Meaning that it can be harmless or harmful. Most flatworms are found in marine or freshwater ecosystems. They can also be found in a host organism where they act as parasites. They can be also found under rocks, plants and debris to avoid direct sunlight.
