Rat

Earlier this school year in agriculture class some of my friends and I were in the garden pulling weeds. One girl pulled up a patch of weeds and discovered a mouse. Several people started scrambling around while the girl wanted to pick it up. One of my friends, an outdoor person scooped up the mouse in such a way as to avoid being bitten. The mouse squealed and the first girl mistook its squeal of fear for a squeal of pain. She then repeatedly said, “Don’t hurt it!” In the midst of this…

characteristics as well. In The Inheritor, the animals exhibit very predictable behaviours, true to their primal instincts, while in Side Bet, the rat almost seems to develop a persona of its own, well beyond what one would expect from a rat. The rat’s vicious personality is unearthed immediately upon introduction, when the author states, “It was a wise and resourceful ship rat and had all the cunning and ferocity of its race.” (Jenkins, par-7), and then further intensifies when the story reads,…

trapped in their own lighthouse by an army of man-eating rats. Throughout the story, "Three Skeleton Key" the author uses literary techniques such as setting, characterization, and suspense to create the…

People First, Rats Second Five indistinguishable figures stand in the arid, earth toned desert, draped under a single distinct tarp created from clearly improvised materials. This makeshift roof provides shade, but not shelter, from the wasteland that these assumed rodents are found in, and in the field of the red and brown earthly hues rich with clay, the landscape is broken only by stark instances of darkness conflicting with the individual, ivory tarp that contributes the bulk of the framed…

During this lab report, we observed the anatomy of a rat. Our task was to dissect a rat and identify its internal organs along with the function of those organs. We carefully removed 10 organs from our rat to take notes on. What we noticed was the homologous structures of the rats were closely related to our own body composition. Their internal organs were positioned in close relation to where ours takes shape, and they looked immensely similar. In addition to their location and size, the rat's…

documentary named “Rat Attack” shows that organisms such as black rats have the ability to impact on ecology of our local environment and the impact can cause disaster to human beings. In the incident, the black rats were originally fed on the bamboo fruits. However, after they reproduced more and more offspring, the bamboo fruits were eventually depleted. Thus, the food shortage led them to eat the rice crops in local farms. By eating the harvest of the farmers, the black rats hugely reproduced…

“The rat had no morals, no conscience, no scruples, no consideration, no decency, no milk of rodent kindness, no compunctions, no higher feeling, no friendliness, no anything” (pg.46). The character of Templeton the Rat in Charlotte’s Web by E.B. White, serves as representation of the dark, evil, immoral side of human nature within the earnest, kind and friendly community of the barn in order to portray both sides of human nature. By including a character such as Templeton in this community, it…

Internally Generated Cell Assembly Sequences in the Rat Hippocampus
(Summary) It was long thought that the hippocampus was the seat of spatial navigation. However, newer models suggest that other cognitive processes such as episodic memory and action planning depend on the hippocampus. Further, these models suggest that this activity might be internally organized cell assemblies. To unpack the role of the hippocampus, these neurons predict where and animal is coming from as well as its…

I am beginning to get far too familiar with rat paws. After thirteen weeks of recording the red-eyed Sprague Dawley rats walking across an elevated horizontal ladder, a circular ladder and a treadmill, I am now tasked with spending my days evaluating the quality of their walking ability. The video begins at an angle below the ladder and the rat appears in the frame. It is roaming around, familiarizing itself with its environment and probably searching for its cage mate. As it moves around the…

Impact of a humanized rat liver model Having a rat model with a more-human like liver will allow investigators to better understand normal and diseased human liver physiology and biochemistry (82). It will allow us to test and compare the ability to repopulate livers with different cell sources which have had limited success in the mouse (3). Primary human hepatocytes have been shown to efficiently repopulate recipient livers (32), however with limited access to large quantities, researchers…
