Were Dinosaurs Warm Blooded

The evidence clearly indicates that this theropod had lung and respiratory mechanics similar to that of a crocodile—not a bird. There was evidence of a diaphragm-like muscle separating the lung from the liver, much as you see in modern crocodiles. These observations suggest that this theropod was similar to an ectothermic reptile, not an endothermic bird. Did feathered dinosaurs exist?

In the passage, the author claims that the Edmontosaurus migrated south in order to survive. However, the lecture refutes the view in the reading and argues that the arguments are not convincing. First of all, the passage establishes the view that Edmontosaurus diet drove them southward because there would have been no plants alive in the North Slope. By contrast, the professor in the lecture contends that Edmontosaur does not need to migrate to South to get food. Edmontosaur can get good quality of plants since it was 24 hours of sunshine during summer.

Ken Ham proudly supports this theory by many displays of dinosaurs in the museum to remind Christians of this theory in Genesis. Bill Nye makes a a spectacle out of this theory, Again, Bill Nye discusses about dinosaur fossils dated back millions of years ago and to go visit secular

The reading states that critics have opposed the idea that Sinosauropteryx was a feathered dinosaur and provides three reasons of support. However, the professor states that the evidence about Sinosauropteryx had feathers is very strong and the critics are unconvincing and refutes each of them. First, the reading states that the fine lines were formed after the animal's death and do not represent functional structures of dinosaur. The professor opposes this point by saying that this point is not likely to be true.

Ray Bradbury used figurative language to describe the Tyrannosaurus Rex in “A Sound of Thunder. ’’ Ray Bradbury compared the legs to pistons, this means that the Tyrannosaurus Rex has strong legs. He compared it’s eyes to ostrich eggs, this means that the dinosaur has big eyes. He also compared muscles to thick ropes, this means that the dino has big thighs.

The inaccuracies for the steps they take is all kinds of logically wrong and makes no sense. Once the dinosaur blood was successfully extracted from the mosquito, they threw in some frog DNA to suture up the gene gaps to make up a dinosaur genome. Then after those steps, they dunked the embryo in an ostrich egg and waited for a raptor to hatch. None of those steps makes sense, and that is because they do not make no sense and it does not work that way. In real life, even if we forget the idea about the dinosaur genetic material that survived in liquid blood form, the frog DNA would be a terrible choice to use as a filler.

The warm blood horse breeds were developed many years ago after the European soldiers came home from Africa and the Middle East where they had captured many horses and they brought the hot blooded Arabian horses home to Europe. The Europeans crossed their heavy war horses which were cold bloods with the hot blooded Arabians and they got the warm blood. The warm blood breeds are very popular eventing horses and they are also used on ranches for herding cattle, roping and other ranch work. The warm blood horses are not as heavy built as the cold bloods.

He was scared, but if he was less selfish and actually thought about what he was doing, he would have stopped talking. Because he continued to speak, he alerted the dinosaur to their being in the area. This led to big consequences for the other four men who were on this hunting trip that the dinosaur spotted them because it advanced on the men, not allowing them to make the first move. The first move is very significant because the attacker can catch them by surprise and it proves that to the opponent that they are the alpha dog. The dinosaur was the one who attacked, which made it hard for the hunters.

The discovery of this mammal was proof that mammals had lived alongside the dinosaurs. It gave scientist a small glimpse into ancient mammal species. Chapter 6– Questions

Title Researchers and scientists have constructed extensive research on dinosaur’s extinction. Speculation instead of real evidence seems common in most theories about the dinosaurs’ extinction. However, Jay Gould’s essay “Sex, Drugs, and the Extinction of Dinosaurs” is the complete opposite of speculation over evidence. Rather, Gould uses the mix of persuasive techniques, such as rhetorical questions, logos, along with profound evidence to not only disapprove of other theories but convince readers of his place on the dinosaur’s extinction.

Once they are in the past and see the Tyrannosaurus Ray Bradbury uses imagery to explain what the dinosaur looks like. The Tyrannosaurus was described as, “...thirty feet above half the trees, a great evil of god, folding its delicate watchmaker’s

The origins of human skin colour: The origins of human skin colour remained an enigma that was to generate a multitude of misconceptions. The true source of human pigmentation was finally revealed with the discovery of the melanocyte in the 19th century. Once the amino acid tyrosine was identified to be the key enzyme in pigment formation, attention focused on elucidating the chemical structure of melanin, an enterprise that remains incomplete.

In 2003, scientists accomplished a feat straight out of science fiction: the cloning of the extinct Pyrenean ibex. However, the resulting clone died soon after its birth due to a lung defect. If a clone of an extinct animal that had died out only three years beforehand could not survive, is there any possibility of a real Jurassic Park? Because no dinosaurs are around to produce offspring, cloning is the only way to create a viable dinosaur embryo.

Reptile scales act as a protective layer to help prevent water loss from their bodies. Mammals are warm-blooded animals and reptiles are cold-blooded animals. Mammals are endothermic which means they can produce and control their body heat internally. Reptiles are ectothermic, they use their resources such as the sun to get

Introduction I. Snakes are reptiles. They are cold-blooded animals with the amazing ability of raising and lowering their body temperatures to adapt to the environment. II. They are distinctively known for their long elongated body and scaly skin. III.
