Axolotl

Regeneration of the axolotl is dependent upon the blastema (Aguilar et al 2015). The blastema formation takes place during dedifferentiation. (Satoh et al 2010). The blastema is formed from progenitor cells in the uninjured limb by re-expressing embryonic genes. The origin of these blastema cells are controversial, as many have a hypothesis of where are originally derived. (Whited & Tabin 2009). For instance, Aguilar et al (2015) suggests that the formation of the blastema is dependent on nerve…

populations. Oil spills cause both decrease and increase in animal populations. For example, the Axolotl Salamander, also known as The Mexican Walking Fish, and brine shrimp are aquatic animals, living in the gulf of mexico. When an oil spill happens in the gulf of mexico these species population’s reduce. This causes there predators to have less food, therefore killing a lot of their species. Also, worms ,the Axolotl Salamanders’ prey, population starts to increase until the population increase…

The Strength to Overcome Perseverance is defined as the quality that allows someone to continue trying to do something even though it is difficult (Perseverance, 2016). The theme of perseverance is shown a variety of ways in literature and art, including through image, text, and through context. Of all of the themes relevant to the selected works from Literature: A World of Writing, perseverance has by far had the greatest impact on the development of the pieces. The speaker, in Annabel Lee, a…

The Separation between the Fantastic and the Real in the Stories of Julio Cortázar Throughout the following research paper, we will develop the literary analysis of the stories "The night face up” “After lunch” “The Axolotl” and “Cefalea” by Julio Cortazar. I chose this author because we can enjoy his literature in which reality is transformed into fantasy, which catches us and forces us to interpret it. The author chosen belongs to the "boom" of Latin American literature. That is why his…

Introduction All animals can heal their wounds. However, some animals can even regenerate lost body parts. Questions have arisen such as, how does this process take place? What is necessary for these animals to perform this job? Experiments have shown that different animals regenerate in different ways. Some may be similar than others and it may have an impact on their lives. The purpose of regenerating tissues is to limit damage and loss of infection. The processes of tissue regeneration…

Embryonic Stem Cell Research Think of an axolotl, otherwise known as a salamander. These creatures can regrow or regenerate any limb or vital structure in their body to survive. I’m not saying that humans can regrow their limbs, but they can come pretty close. Like the cells in an axolotl, embryonic stem cells have regenerative properties that can regenerate in a human body. They are immortal and have unlimited developmental possibilities. Embryonic stem cells come from human embryos, which…

Introduction Rakoczy, Ehrling, Harris, and Schultze 's experiments wanted to evaluate how young children accept advice on topics they have no knowledge in; while how adults make judgements has been well-studied, the way children make judgements has not (Rakoczy et al., 2015, p.71-73). Through these experiments, Rakoczy et al. (2015) wanted to determine whether children actively sought advice from better informed, as adults would; additionally, they wanted to see whether or not children were…

As a rule, the gill area is greater in fast-moving crabs (Portunids) than in sluggish bottom dwellers; decreases progressively from wholly aquatic, to intertidal, to land species; and is greater in young crabs than in older crabs. Often the gills are enclosed in protective chambers, and ventilation is provided by specialized appendages that create the respiratory current. As in cephalopod mollusks, oxygen utilization is relatively high—up to 70 percent of the oxygen is extracted from the water…
