The article states that dinosaurs unlike other modern reptiles are endotherms. They are able to maintain constant body temperatures in even cold weather. The article provides three reasons of support. However, the professor explains that scientists believe otherwise and refutes each of the author's reasons. First, the reading claims that because dinosaurs lived in polar regions where there is extreme cold temperature,dinosaurs were still able to maintain a temperature above the external environment. The professor refutes this by saying that polar regions in those period when these dinosaurs lived were warmer than it is now. Second, the article posits that leg positioning of dinosaurs wherein their legs are underneath their body allows them
At first, the reading passage posits that the diet for these dinosaurs proves that they had to migrate to find plants. Conversely, the professor refutes this point by imparting that this ratiocination is invalid on the ground that there was in some period a warm climate in this area. According to the professor, the 24 hours sunshine eventuated in warm weather and extensive daylight would provide a desirable environment
First of all, the passage states that the special kind of dinosaurs , Edmonstosaurus, had to migrate because of finding food to survive, But on the other hand the professor states that in that period of time the weather exchanges were not notable as they are today, and whether the seasons change the vegetation amount didn't vary a lot. Also she noted that even if the vegetables were hard to find in winter, there would be other nutrition available.
In 1993, Steven Spielburg’s Jurassic Park introduced the concept of bringing extinct species back. In 2003, a team of Spanish and French scientists took Spielburg’s movie to the next level—they successfully brought back the Pyrenean ibex, a species of wild goat (93). With increasing rates of extinction, the scientific community is debating whether or not this process of de-extinction should continue to be pursued. Although it would be remarkable to visit an exhibit featuring a saber-tooth tiger or woolly mammoth, these animals went extinct for a reason; humans should not bring back extinct animals, but instead use the funding for more practical purposes.
What is apathy anyway? Apathy is the lack of interest, enthusiasm, or concern for what is going on around us. We all experience apathy occasionally when we feel unmotivated or uninterested in our daily tasks. However, this is normal from time to time while constantly behaving without feeling is not. As a result of people wanting to fit in with others so they will be liked, being wasteful, and wanting others to get hurt they have caused a growing immense problem.
Because warm blooded animals don’t have to rely on their environment for body temperature, they are able to hunt at any time of the day or in any season, which is a great advantage over cold-blooded animals. Therefore this “type of intense activity needs a fast metabolism which is much too high for a cold-blooded animal. Secondly, cold-blooded animals have a hard time living in cold climates and dinosaur fossils have been found in the colder environments” (Eschberger). However, scientists believe warm blooded animals would have suffered from the heat in warmer climates, where many fossils have been discovered. Beverly Eschberger discusses how dinosaurs must have been only warm blooded animals due to the factors of, bone structure, and histology, growth rates, predator to prey ratios, speed and agility, rate of evolution, similarities with birds, and insulation. She also explains the disadvantages of being a warm blooded animal: “a much larger expenditure of energy to maintain elevated metabolism and a commensurate increase in food requirements” (Eschberger). Just as the conclusion that dinosaurs were truly warm blooded becomes clearer, factors from the cold blooded side switch everything around. Gigantothermy, rate of food supply, respiratory turbinates and lung structure all cause scientists to believe dinosaurs were in fact cold-blooded. There have been many attempts to find the real resolution of whether or not dinosaurs were warm or cold
Second,the writer says the fact that edmontosaurus lived in herd prove the migration hypothesis.Professor disagrees
Science AOL Task There are many theories on how the dinosaurs became extinct over 65 million years ago. The theory that is most common, is the asteroid theory. The asteroid theory proposes that an asteroid hit the Earth, resulting in overwhelming amounts of ash pouring into the atmosphere. Another theory is the volcanic eruption theory.
Sauropoda were a clade of large dinosaurs that had long necks, long tails, and thick legs. The biggest mystery concerning the sauropods was the function of their necks and whether the animals could keep their necks raised. Senter (2006) hypothesized that sauropods’ necks were for sexual selection. In 2009 it was hypothesized that it was not possible for sauropods to raise their necks for extended periods of time (Seymour et al. 2009). Another hypothesis for the function of a sauropods neck was for reaching high food sources (Christian 2010). Another hypothesis (Taylor et al. 2011) proposed that sauropods’ necks were not for sexual selection and instead served another function. Henderson (2013) hypothesized that sauropods’ necks could have been
I believe in the possibility of dinosaurs being in my backyard (SA) as we have found numerous ways for fossils to be preserved and these ways can and have been done in South Australia.
A major platform of the indigenismo movement was anticlericalism. There are three major positions generally taken when speaking about indigenismo and religion. First is that of the literary critic. Religion in the works of Lopez y Fuentes and Magdaleno is symbolic of power struggle. Authors sought to influence the emotions of the public by painting priests as villains. A second position is taken by the modern historian who claim that the Church held too much power over the indigenous peoples. It was an obstacle to modernization efforts and therefore ought to be removed. A third stance focuses on the religious terminology of national projects, stating that while the Catholic institution
Jurassic Park by Michael Crichton demonstrated many dinosaur characteristics and behaviors. The dinosaurs were fictionally characterized to appeal to the readers. By examining the dinosaur’s appearance and behaviors of dinosaurs such as the duckbilled dinosaur, velociraptor, hypsilophodontids, dilophosaurs, Triceratops, apatosaurs, Tyrannosaurus rex, stegosaurs, and maiasaurs distinguished whether the evidence existed in the field of paleontology. The behaviors and characteristics of the dinosaur are divided into three factors as behaviors that were supported, not supported, and no evidence to support or refute the behavior.
Although both the lecturer and the writer try very hard to explain whether dinosaurs are endotherms or not, their standpoints are clearly different.
So what killed the dinosaurs? Without having any background education in science it is hard for the general public to comprehend such matters and they rely on the knowledge of the scientists in this field. Although there has been much research on the subject nobody has come up with a conclusive answer. And we are left to read the countless articles, all having their own opinions as to the mass extinction. One such theory is that a shift in the solar system could have caused the mass destruction. According to an article published in Nature magazine,
The debate over whether marijuana should be legalized has long troubled many American citizens. There are many political aspects that have to be taken into account when making a big federal decision such as this. However, long before America was even an idea, many cultures had harnessed the plant, and used it for many primitive medical procedures. Within certain states it is legal to use marijuana for medical treatments, but this is a relatively new idea in the United States. However, marijuana was not always deemed an illegal substance and because of its inherent medical value should be legalized at the federal level.
Rapid climate change also ends up on the suspect list of possible dinosaur extinction events. During the latter part of the Cretaceous Period continents broke up causing volcanoes to erupt and fill the sky with gas and ash resulting in a drastic climate change (“Dinosaurs Climate Change and Biodiversity”). The shifting of continents changed the Earth’s landscape, altering weather patterns and overall climate (“Dinosaur Extinction Theories”). Also, over a long period of time, climate gradually changed. Ocean habits changed, temperatures grew much more extreme causing scorching summers and frigid winters (Norell, Dingus, and Gaffney). Radical temperature changes like these led to a green-house effect, making life for the dinosaurs a lot
