Rat

1) List at least three ways in which rats are similar to humans. a) Rats, just as humans, give birth to living young. b) It has been shown that rats and humans can contract the same diseases. c) We have similar anatomy 2) Describe a rat 's foot structure and for what it might be useful. How is this similar to a human’s foot? How is this different from humans? Rats have two hind feet with five toes, and on each toe is a sharp nail. Its hind feet are significantly larger than it’s front…

Each rat was completely isolated, left alone in their cage with nothing to occupy themselves with except from the drug additive water. This in turn gave ground to a new experiment consisting of 2 rats this time in what was known as “Rat Park”. The park was a rat haven. There were plenty of things to do, the interior was luxurious and more importantly, there were plenty of rat friends to socialise and converse with. Like the first experiment, Rat Park also had two water bottles…

Hawaii. A ravishing bizarre tropical paradise with sceneries you would die to look at. If you love to be in a tropical paradise, Hawaii is the place to go to. Sadly, Hawaii has lost plenty of its native animals and plants over the years.This problem occurred when invasive species came to Hawaii around the 1780’s. Invasive species is a term they call animals, plants, and other organisms that do not belong in this specific area. They did a lot of harm to the native plants and animals that lots…

know why cats and rats hate each other? It’s a common occurrence to hear that rats and cats hate each other, but do you know why? In Cat and Rat: Legend of the Chinese Zodiac they have a race to decide which months the animals will be connected with. It shows how Rat betrayed Cat by pushing her so he could win the race despite saying they’d win together. In How Cats and Mice Became Enemies it shows how Cat and Rat needed to cross a river so they used a pumpkin. In this story Rat betrays Cat…

The objectives of this dissection was to examine the digestive system, the shape and location of the organs. Another objective of the rat dissection was to know the function of the organs in the respiratory system. For our last objective, for the circulatory system we had to identify the blood vessels and state their function. Rat dissections are done in this course because students get to see, touch and examine the organs in the body. Seeing these organs in person instead of just off a piece of…

Pure-bred Sprague Dawley rats (brown laboratory rats) are to be used in this experiment. These rats are preferred due to known calmness and ease of handling. To reduce variability, rats of the same weight, age, and gender will be chosen. Thirty-seven ADHD rats and thirty-seven non-ADHD rats will be chosen. This provides a sample size large enough to produce statistically significant values. Because there is no physical biological marker for rats with ADHD, behavioral symptoms must be…

task, thus detecting the underlying attentional deficit. Our results confirmed the PMS phenotype in the rat model, as observed by their higher latencies on performing trials and were similar to the attentional deficits evidently observed even in PMS patients. The insignificant difference in the reward collection time demonsrates that there is no lack of motivation in the Shank-3 deficient rats. So we infer that the inability to perform is…

As rat population grows, infestations has become a rapidly growing problem for those residing in areas prone to warm, dry climate as climate change is among us. These rats have been said to have retreated from the sewers due to flooding and unwelcoming shelter for their own. Article #1 speaks of the rising percentage of reports with the quote, “calls to pest controllers rose by 18%... this figure will increase by a further 20% this year”. Firstly, the commonly known brown, Norway, rats infest…

The boy’s name was Steve York and due to his change towards the wrong path, there was a high possibility that he would not be able to graduate. However, his principal had noticed that in…

“Elevated surface temperature depresses survival of banner-tailed kangaroo rats: will climate change cook a desert icon” by Moses, Frey, and Roemer is about the ecological and physiological effects on Kangaroo rats based on uprising temperatures. The species used for this experiment was the Kangaroo rat also known as the Dipodomys spectabilis. This species was used in this experiment because of previous physiological research and because it is a species that will be suitable to observe behavior…
