BIOL 152-35 Professor Weller 14 February 2012 Effects of Temperature on Goldfish Respiration Introduction This experiment was designed to identify the effect of cold-water temperatures on the respiration rate of goldfish. The respiration rates helped to identify the goldfish as being ectotherms or endotherms. Organisms exchange gases with their environment through a process called respiration or breathing. Aerobic respiration‚ also known as aerobic metabolism‚ occurs when oxygen is taken

How fever works How does fever happen? Once endogenous pyrogens have been produced by the primary immune response‚ they must travel to the brain to actually induce fever. After their increased production by activated immune cells‚ cytokines such as IL-1‚ IL-6‚ and TNF are distributed throughout the body through the blood‚ as they are all soluble proteins. Now‚ then‚ these cytokines must have a target to signal and cause a reaction. PGE As it plays a central role in thermal regulation‚ it

Pre-warming patients to prevent hypothermia in recovery: A literature review Every day patients undergo surgery with general anesthesia for simple procedures like hernia repairs or breast biopsies. Loved ones are escorted into cold preoperative areas where nurses have them remove every stitch of their own clothing and replace them with a chilly‚ threadbare piece of fabric which ties together a handful of times and falls‚ for most‚ to the knees at best. The preoperative nurse then

Australian Ectotherms and Endotherms- temperature regulation Part A :Types of Temperature regulation 1. Write down the meaning of the terms endotherm and ectotherm. Consult a textbook if necessary. a. endotherm Endotherms are animals that can maintain a constant internal body temperature. For instance mammals and birds are true endotherms that can maintain a constant internal body temperature b. ectotherm Ectotherms are animals that are not able to regulate their body temperature or in simple

Molly Curtis A&P 1 Case Study1 Marian suffered from a heat stroke causing her body to experience hyperthermia. Marian body went through the process of homeostasis from experiencing hyperthermia. “Homeostasis is a state of body equilibrium or stable internal environment of the body.”(Marieb 8) Homeostasis protects the body by allowing it to adapt to the environment. Marian homeostasis tried to cool the body but failed. Though Marian was lucky her daughter found her in time. When a heat

Your answer should consider both the animal itself and the implications of good or bad welfare on the research being carried out. You might like to think about the effect that welfare has on the animal’s response to certain research treatments for

disruption of thermoregulation can potentially cause unbalance within the body. As referenced in Resource B‚ one of the cyclists called Sally hurt herself while biking on Day 4. She “clipped my back wheel and down she went‚ massive graze on the knee and nasty gash on her elbow.” (Resource B) Yet in Day 6‚ it is mentioned that among the hot temperatures‚ Sally was battling a fever and nausea due to an infection from one of her injuries. Fever and infection can offset thermoregulation as a fever elevates

experiment was to learn about the thermoregulation‚ and more specifically ectotherms. The experiment was designed to learn how ectotherms rely on external temperature for heat. The hypothesis of the experiment was whether there was temperature variance between two habitats‚ and how it affects the ectotherms. To test the hypothesis‚ we used I-buttons to record the temperature and ANOVA test for p-value. The results supported the hypothesis. Introduction: Thermoregulation is a process that allows your
