...more than when we are resting. Exercise is carried out by increasing the respiration rate and the heart rate. (BBC Bitesize 2014) Exercise occurs when the muscles contract and relax which create movement. Energy for cells is created in the mitochondria of every cell, through the process of cellular respiration (Glucose + Oxygen -----> Carbon Dioxide + Water + ENERGY). The Mitochondria is known as the "powerhouse" of all cells and they act like...

EVOLUTION CONNECTION Life before and after Oxygen 91 102 103 Aerobic versus Anaerobic Lifestyles BIOLOGY AND SOCIETY Marathoners versus Sprinters Track-and-field athletes usually have a favorite event in which they excel. Some runners specialize in sprints of 100 or 200 meters. Others excel at longer races of 1,500, 5,000, or even 10,000 m. It is unusual to find a runner who competes equally well in both 100-m and 10,000-m races; most runners are more comfortable running races of particular lengths. It turns out that there is a biological basis for such preferences. The muscles that move our legs contain two main types of muscle fibers: slow-twitch and fast-twitch. Slow-twitch muscle fibers can contract many times over a longer period but don’t generate a lot of quick power for the body. They perform better in endurance exercises requiring slow, steady muscle activity, such as marathons. Fast-twitch muscle fibers can contract more quickly and powerfully than slow-twitch fibers but also...

Find a media piece—article, video, presentation, song, or other—related to the scientific method, creating hypotheses, or designing experiments. Include the link or reference citation for the piece and describe how it helped you better understand how the scientific method is used to create hypotheses and experiments. * * “The Scientific Method Video,” is a unique way to present the scientific method by using rap to emphasize the important points. This includes that the scientific method begins with a question based on an observation, and then a hypothesis and prediction are made, experiments are conducted (which need to be reliable, include a variable and a control), and lastly findings are reported. It has been a long time since I have gone over the basics of the scientific method. This video helped me review what I find so fundamental and second nature. Also, I think it is helpful to note that as the textbook states, “These steps guide scientific investigation, but working scientist typically do not follow them rigidly.” This video is an interesting tool to review the scientific method and how it is viewed by the student rappers.

...4srinad@gmail.com Abstract--- A landfill is a site for the disposal of waste materials by burial and is one of the most common methods of solid waste management in various parts of the world. Significant environmental and economic benefits can be gained by making small changes in the way the landfills are operated. Bioreactor landfill is a promising biotechnological option for faster stabilization of Municipal Solid Waste (MSW). It changes the goal of landfilling from the storage of waste to the treatment of waste. In a bioreactor landfill environment, the solid waste actively decomposes rather than being simply buried in a dry tomb. This active decomposition is possible because over half the MSW is comprised of organic material (food, paper, etc.), which will decompose fairly rapidly under the right conditions. Rather than being kept dry, the solid waste is actively moistened by injecting leachate into the landfilled solid waste to accelerate decomposition. The anaerobic conditions in a conventional landfill can be replaced with aerobic conditions by introducing air into the solid waste and thus enhancing the biological process. Studies show that a bioreactor landfill transforms and stabilizes the readily and moderately decomposable organic waste constituents within five to ten years. A bioreactor increases the potential for waste to energy conversion, stores and/or treats leachate, recovers air space, and ensures sustainability. Sustainability has the greatest potential for...

...Blood Doping Biology Research Paper Samantha Reid University Seven time consecutive Tour De France champion and yellow rubber band seller of the decade openly admitted to blood doping. His name was Lance Armstrong and not only did he live through cancer, but he was one of the greatest athletes the world has ever known. His list of achievement goes on until his banishment for professional racing and the stripping of his titles. He admitted to using banned substances including steroids and blood doping in an interview with Oprah Winfrey on January 17, 2013. Why would a man with so many accomplishments cheat the system with prohibited procedures and the use of illegal performance drugs? The three topics that rise in answering why Lance Armstrong blood doped is explaining what blood doping is, the advantage and disadvantages of it and drug use in profession sports. To describe what blood doping is one must first understand some key terms. Hemoglobin is a red protein responsible for carrying oxygen in your blood. Another key term is the cardiovascular system and this is an organ system that distributes the blood throughout the body to deliver nutrients and remove waste. And the respiratory system is the organ system that carries out gas exchange in your body. These three things all work together hand in hand like a smooth operating clock. The respiratory system gets the oxygen from the air and transports it to the blood carried in the hemoglobin. The oxygen enriched hemoglobin...

...The effect of temperature stress on dairy cows J. Praks When environmental temperatures move out of the thermoneutral zone (or comfort zone) dairy cattle begin to experience either heat stress or cold stress. Either stress requires the cow to increase the amount of energy used to maintain the body temperature and there is less energy available to produce milk. Thermoneutral zone is the range of environmental temperatures where normal body temperature is maintained and heat production is at the basal level. The ranges of thermoneutral zone are from lower critical temperature (LCT) to upper critical temperature (UCT). LCT is the environmental temperature at which an animal needs to increase metabolic heat production to maintain body temperature. UCT is the environmental temperature at which the animal increases heat production as a consequence of a rise in body temperature resulting for inadequate evaporative heat loss (Yousef, 1985). Thermoneutral zone depends on the age, breed, feed intake, diet composition, previous state of temperature acclimatization, production, housing and stall conditions, tissue (fat, skin) insulation and external (coat) insulation, and the behaviour of the animal. UCT is given as 25-26 ºC , LCT as a range from -16 to -37 ºC for dairy cows (Berman et al., 1985; Hamada, 1971). LCT for newborn calves is 10 ºC in dry and draught-free environment. LCT decreases to 0 ºC by the time the calf is 1 month old. Temperature-humidity index (THI) could be...

...THE EFFECT OF WOOD ASHES IN HASTENING THE FRUIT RIPENING OF Musa acuminata (banana) and Mangifera indica (mango) A special problem presented to Ms. Eukene Oporto – Bensig In partial fulfillment in the requirements of Botany 10 Submitted by: Theresa Mae Toboso Ianne Clarise Ortiz Janine Bernice Bonghanoy Eullen Marie Cale Christian Bernard Serino March 2013 ABSTRACT The study aimed to find out the effectiveness of wood ashes in hastening the ripening of fruits specifically, mangoes and bananas. This study has eight set-ups with four as the control variable and the other as the experimental. The set-ups are as follows: Set-up 1 and 2 with one unripe mango in each and ashes; 3 and 4 with four pieces of banana in each with ashes; 5 and 6 with just one mango in each; and 7 and 8 with just four bananas in each. The ripeness of the fruits was defined by the color of its exocarp and its growth rate. Results show that the set-ups containing banana and ash ripened faster compared to the ones without ash and that there was no significant difference in all set-ups of the mangoes. The researchers concluded that wood ashes are effective in hastening the ripeness of banana but not mangoes. CHAPTER 1 INTRODUCTION The most essential elements for the production of fruit are nitrogen potash, phosphoric acid, and lime. Wood ashes contain potash, carbonate of lime and a small amount of phosphoric acid, which are plant foods. Potash a component of wood ash that constitutes...
