Song of the Hummingbird by Graciela Limon is about the fall of the Aztecs at the hands of Cortes and Spanish conquerors from the point of view most people never learn about--the Aztecs. The story takes place in 1582, when an indigenous woman, Huitzitzilin, also known as “Hummingbird”, recounts her story about the coming of Cortes and the Spanish to a young Spanish monk, Father Benita Lara. Father Benita Lara realizes that Huitzitzilin’s views on the events don’t aline with what was taught in Spain and he becomes intrigued by her version of what happened. Song of the Hummingbird emphasises several important topics: clash of cultures, strength, betrayal and acceptance, and the truth behind history. I enjoyed reading this book because it allows

Caffeine, Nicotine, ethanol, and a control solution were tested. The heart rate of Daphnia was measured after exposure to each of the chemicals. After testing, it was found that ethanol depressed the heart rate while exposed, but the heart rate stabilized after exposure. With exposure to nicotine, the heart rate increased by 20%. If more nicotine was added, the effects were varied and sometimes irreversible.

We are all familiar with the notion of “pleasure.” Simple pleasures are ever-present in our lives but complex, extended pleasures are fulfilling yet fleeting. They bring about intense experiences to gratify our desires, although they are not a necessity, in the same way slaughtering and plating an overhunted species is not absolutely imperative. However, despite my own belief that an endangered species is not to be poached upon, I commend Liz Alderman for completing “Chefs Fight for Songbird” in a way in which she successfully set key points from both sides of the arguments while also discreetly and strategically establishing and backing her own position in the feud. For those completely unfamiliar with the topic, Alderman might be able to

Nonetheless, besides fish, many other kinds of poikilothermic animals, such as snakes and frogs, use lungs instead of gills to breathe, and further researches may be conducted to explore if caffeine has an effect on their metabolism. For example, forty northern leopard frogs with similar body size will be captured and divided into twenty trials, and each two frogs will be tested in the same control and experimental conditions as the goldfish metabolism experiment did. The collected slopes of oxygen concentration will then be converted into oxygen consumption rate and analyzed by the paired t-test. If the difference in the oxygen consumption rate between the control and experimental groups is statistically significant, this experiment will show that caffeine affects the metabolism of frogs, one kind of poikilotherms that use lungs to

Continuing on, Ellison introduces a new fact to the audience, that jazzmen were labeled as cats because they were legends.
