Analysis: The graph of oxygen uptake vs time taken to run 1.5 miles has a negative linear association. As oxygen uptake increases‚ the time taken to run 1.5 miles decreases. This is can be seen through the gradient which has a value of 0.1705. This means that as the oxygen uptake increases by 1 ml/kg the amount of time taken to run 1.5 miles tends to decrease by approximately 1.7 minutes. The graph has a moderate relationship because the data is scattered in a wide band along the line of best fit

Ventilation and Oxygen Consumption Results Oxygen Concentration Oxygen concentration in water can be altered by the conditions it is exposed to. For instance cold water has a higher oxygen concentration than warm water. In our experiment we were able to observe the change in oxygen concentration of water at two different temperatures (15C and 25C) with a fish in each environment. Our results proved that the starting oxygen concentration of the cold water was higher than that of warm water. It also showed

The Welcome Table vs. Country Lovers When it comes to writing there are many different types of writing styles. Two different types of literature are short stories and poems. These two types have many different similarities and differences. It is also how you understand the literature. Some similarities are how they can have the same theme or possibly the same point of view. The differences are how the author uses emotions‚ the length of the literature. I believe that poems use

present and that of the gangue. Principle: Concentration is done mainly to increase the percentage of pure metal. It is of 3 types. 1. Gravity separation (Hydraulic washing) 2. Froth floatation 3. Magnetic separation. Froth floatation: This method has been in use for removing gangue from sulphide ores. In this process‚ a suspension of the powdered ore is made with water. To it‚ collectors and froth stabilizers are added. Collectors (e. g.‚ pine oils‚ fatty acids‚ xanthates‚ etc.) enhance non-wettability

Standard Methods for the Examination of Water and Wastewater 5210 BIOCHEMICAL OXYGEN DEMAND (BOD)*#(1) 5220 CHEMICAL OXYGEN DEMAND (COD)*#(2) 5220 A. Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods

Analysis of Oxygen Bearing Organic Compounds James Matthew Jocson*‚ Gianvittorio Lanta‚ Chiqui Ann Llamado‚ Jeron Manaig College of Science Department of Biology University of Santo Tomas‚ Manila‚ Philippines Abstract Five oxygen-bearing organic compounds were given namely Methanol‚ 2-propanol‚ tert - butanol‚ formalin‚ and acetone. Different tests were done to each sample to differentiate their characteristics. These test were Dichromate test‚ Tollens Test‚ DNPH test‚ Iodoform Test‚ and Lucas

WATER OUR LIFELINE Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of the fluids of living things. As a chemical compound‚ a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚ 1.7% in glaciers and the ice caps of Antarctica

Fertility and Population Policy: the Singapore Experience Mui Teng Yap Introduction Singapore has long been known for its use of social policies to influence fertility/reproductive behaviour. This began in the late 1960s/early 1970s and continues to the present‚ although the demographic objective has changed from anti-natalist to selectively pro-natalist. The turning point came in the mid-1980s after about a decade of below-replacement level fertility. The impetus must have been the results of

The Importance of Oxygen for Life PURPOSE: To determine whether test tubes filled with bacteria‚ a few salts‚ distilled water‚ and glucose would grow in the presence or absence of oxygen. By adding oxygen to certain tubes and withholding it from other tubes‚ one can determine which bacteria grow the most efficiently. HYPOTHESIS: The test tubes of bacteria with oxygen will grow and thrive over the test tubes without oxygen. METHODS: Using the data shown in Table 7-A-1‚ construct two graph
