Earthworm

A big question that hit the media in 2013, is should Sandhill cranes be hunted? In 2014 Tennessee approved the law due to the fact, the population of these specific birds was over 600,000. Along with the high numbers, there population continuously increases. Although the species is not endangered, geologic experts don’t want to have these birds hunted because, Sandhill cranes are one of the oldest birds. In addition Geologic experts have fossils of the birds that are 9 million years old. People…

Glycolytic breaks glucose down into pyruvic and lactic acid. The enzyme is essential to the earthworm's digestive system and process. Proteolytic enzymes are used to help in the digestion of proteins. “Proteolytic enzymes are localized in the earthworms' alimentary canals”. They play an important role in worms alimentary digestion by breaking down proteins. Pepsin is the first proteolytic enzyme used in the breaking down of protein, it breaks down the dietary protein into denatured and…

and claims territory. The niche of the Malagasy Civet is to feed upon invertebrates, small amphibians and some small mammals. The Fossa fossana typically sleeps in hollow trees and rock crevasses during the day, to wake up at night and forage for earthworms, rodents, bird eggs, and sometimes fruit. During the winter, 25% of the Malagasy Civet's body weight is fat stored in it's tail. The Malagasy Civet births very well-developed offspring that are born with their eyes and are ready to crawl…

discovered a new method for non-surgical nerve regeneration. Previously, it was assumed that the regeneration of the selective-barrier around the axolemma was necessary for the nerve regeneration process to begin however, Bittner, through testing on earthworms and crayfish, found that by covering the ends of the severed axons in a calcium free solution, the nerve repair process in terminated and the selective barrier is not constructed around the axons. Following this, the axons are brought…

Death of birds A. In Illinois and Alabama, birds started to disappear - Michigan State University found out the link between death of robins and spraying of elm trees - They found out that earthworms were contaminated by the poison and that is what caused the birds to die - Another scientist found that trees were sprayed twice a year with DDT - Population of American eagle decreased and study has shown that they had an exposure to DDT Chapter…

INTRODUCTION Hypothesis: to establish whether organic foods are worth the money we spend on if and how health, environment and economic factors influence our decision. Research Question: Organic foods. Why bother? Aim: To institute the fact that organic products are healthier than conventional products. The difference between farming methods and which method is more convenient. To establish whether Organic food is a passing FAD and to understand the effects organic food has on health,…

During this lab flatworms and earthworms anatomy and physiology were examined. Unfortunately as the experiment continued with the bring home flatworm, it died in my house as it was too warm in my room and on the shaded part of my desk. The planetarium was cut up in two segments in order to see whether the anterior or posterior side of the flatworm would regenerate the fastest. My hypothesis was as stated, if the flatworm was cut above the pharynx in the branched gastrovascular cavity (before the…

Regeneration is the process of renewal or restoration of a body, part of the body or biological system after a wound or as a normal process. It is the process that makes the genomes, cells and organisms flexible to natural changes that cause disturbances or damage. All species are able to regenerate from bacteria to humans. Regeneration can be of two types: it can be complete when the new tissue is equal to the lost or incomplete tissue when the necrotic tissue presents fibrosis. Different…

their eggs in warmer months.That is how they have eggs. Finally, here are many things that toads can eat and that is what will be discussed in this paragraph.While toads get more into an adult toads can eat whatever but most toads “eat insects and earthworms” (VanDeWalle 3), that is because they have learned how to eat and became better at it. People may not know what they eat or may think they are vegetarians. While frogs eat insects,spiders and other invertebrates. (VanDeWalle 8).When…

This is a book report on the animal The Axolotl, which comes from Aztecs. Axolotl means water, while xolotl means monster. So this animal is considered a, “Water Monster.” It is a non-native fish that also goes by the name, “Mexican Walking Fish.” It’s an amphibian, like a frog, and is in a paused state of metamorphosis. Their classification is in the phylum, Chordata. The Axolotl was first founded in 1789, in Mexico City. The labs that they were founded in and tested on were in Paris. They are…
