Materials: Thermometer, three syringes, pen Methods of testing: First of all, we recorded the temperature (in Celsius) and the volume of the gases within the 3 syringes (in cc). We noted the recorded data in a table. Then, we let these three syringes in a freezer for two days at temperature -20 Celsius. After two days, we removed the syringe from the freezer and recorded the temperature and the volume of the gas.

Then, x + 3y + x + 100 = 150 5 4. a A 2. b 3 y 2 Hence, y can take only even values. ⇒ 2x + 3y = 650 ⇒ x = 325 − 2 3 cm Also, 325 − 3 3 y < y < 325 − y + 100 2 2 B D 4 cm 6 0° F E C 3 y < 425 2 ⇒ 130 < y < 170 As y is even, the number of possible values of y ⇒ 325 < y + 168 − 132 + 1 = 19 2 Hence, the number of different possible values of the largest number i.e. (x + 100) is also 19. = 3. c Let the number of boys be x and the number of girls in the class be y. From statement A: x = 2y + 5 We cannot find the exact values of x and y. Hence, Statement A alone is not sufficient. From statement B: 0.4x = y We cannot find the exact values of x and y. Hence, Statement B alone is not sufficient. From statements A and B: Solving, we get x = 25 and y = 10. So the total number of students in the class = 35 Hence, both the statements together are required to answer the question. Let’s draw AF perpendicular to BC. In ∆ADE, as AD = AE ∠AED = ∠ADE = 60° ⇒ ∠DAE = 60° Hence, we can conclude that ∆ADE is an equilateral triangle. ⇒ AF = 3 × 4 = 2 3 cm and DF = FE = 2 cm 2 In ∆ABF, using Pythagoras’ Theorem, AB = AF2 + BF2 = (2 3)2 + 42 = 2 7 cm. 5....

...protective shell-like barrier that surrounds the ovum. The first sperm that penetrates fully into the egg donates its genetic material (DNA). The egg then polarizes, repelling any additional sperm. The resulting combination is called a zygote, a new and genetically unique human organism. The term "conception" refers variably to either fertilization or to formation of the conceptus after uterine implantation, and this terminology is controversial. 3 Stages of Prenatal Germinal stage Embryonic stage Fetal stage Embryonic stage The embryonic period in humans begins at fertilization (penetration of the egg by the sperm) and continues until the end of the 10th week of gestation (8th week by embryonic age). The embryo spends the next few days traveling down the Fallopian tube. It starts out as a single cell zygote and then divides several times to form a ball of cells called a morula. Further cellular division is accompanied by the formation of a small cavity between the cells. This stage is called a blastocyst. Up to this point there is no growth in the overall size of the embryo, as it is confined within a glycoprotein shell, known as the zona pellucida. Instead, each division produces successively smaller cells. Changes by weeks of gestation Gestational age vs. embryonic age Gestational age is the time that has passed since the onset of the last...

...dealers and customers, while streamlining site management Summary Suzuki Motor Corporation (SMC) founded The Motorcycle and ATV Division of American Suzuki Motor Corporation (ASMC), Brea, CA, in 1963. ASMC markets motorcycles,ATVs and Scooters via an extensive dealer network throughout 49 states. ASMC’s parent company, Suzuki Motor Corporation, based in Hamamatsu, Japan, is a diversified worldwide manufacturer of motorcycles, ATVs, scooters, automobiles and marine engines. Founded in 1909 and incorporated in 1920, it has 120 distributors in 191 countries. When Suzuki needed an updated web experience and more control over their content they looked to their agency of record, Questus, who recommended Sitecore. Challenge The purpose of Suzuki’s site is to market their products and drive customers to their local dealers. The dealers are the ones selling the Suzuki products, so it’s important for Suzuki to keep their dealers happy. • Dealer Locator – a tool to help end users find the dealer nearest them • Dealer Center - A place for dealers to access all of the latest promotions and participate in dealer-only programs Previously, Suzuki was using an aging home-grown CMS to manage their web content. However, the interface wasn’t user friendly and it required a developer to make any changes to the content, which was costly and time-consuming, not to mention error-prone. E-commerce and promotions were also a challenge to manage on the previous site. ...

Published 2010. All rights reserved. Introduction It is clear that developers, designers and the community are increasingly valuing the aesthetic and environmental potential of water features–structures such as lakes, ponds and fountains–which are becoming increasingly common in new developments and urban renewal projects. At the same time, walking and cycling paths are also being provided to take advantage of the recreational opportunities presented by natural water courses throughout our suburbs. These features add to the vibrancy of our community, but they also present an element of danger, particularly for children. At the time of drafting this document there were no Australian guidelines or other reference documents dealing with safety issues associated with these features...

Genet., 69(4) (Spl. issue): 352-360 (2009) Analysis of diversity among cytoplasmic male sterile sources and their utilization in developing F1 hybrids in Pearl millet [Pennisetum glaucum (R.) Br] C. Tara Satyavathi*, Sakkira Begum, B. B. Singh, K. V. Unnikrishnan and C. Bharadwaj Division of Genetics, Indian Agricultural Research Institute, New Delhi 110 012 Abstract The present study aims at analysis of diversity among parental lines of different cytoplasmic sources and their utilization in developing F1 hybrids. Seven male sterile cytoplasmic lines belonging to A1 – 3; A4 – 2 and A5 – 2 were crossed with three elite restorers. The cluster analysis done with molecular data obtained from genomic DNA using SSR markers grouped the parental lines belonging to A1 cytoplasm into one cluster, A4 into one and A5 into the other. The assessment of the performance of the F1 hybrids was done through standard heterosis, heterobeltiosis and economic heterosis. The study clearly indicated that all the seven cytoplasmic male sterile lines coming from different cytoplasmic sources are capable of producing new superior hybrids. Physiological characters like chlorophyll, relative carotenoids and root length density have also been studied to assess the performance of parents and F1 hybrids. Higher economic heterosis was observed for yield in A 1 cytoplasm compared to A4 and A5 cytoplasms. Desirable effects of earliness and maturity can be obtained using A4 cytoplasm while desirable...

...CHAPTER 1 INTRODUCTION 1.1 Background of the Study In this age of industrialization and globalization, the importance of electricity is unquestionable. Considered as one of the basic needs of mankind, it is essential not only in performing household tasks or maintaining livelihood activities, but also in improving people’s well-being. Through electrification, people have greater access to productivity and developments in technology, infrastructure, health, education, communication, and even modern and sustainable livelihoods. However, despite its importance there are still many households especially here in Mindanao which do not have connection to electricity. Based on the results of the 2008 Annual Poverty Indicators Survey, two in every five poor Filipino families living in the urban or rural areas do not have electricity in their homes (National Statistics Office, 2008). The reason for this is the high cost of electricity.For the economically disadvantaged, electricity is considered a luxurious necessity. Another problem that confronts electricity utilization both in the urban and rural areas is the frequent power rate increase and the prevailing power shortages. Based on the situation here in Iligan City as of May 2013, insufficient power supply caused Iligan Light and Power, Inc. (ILPI) to purchase additional 10 MW from MPC (Mapalad Power Corporation). This resulted to increase in power cost from Php 6.53 per kWh to Php 7.67 per kWh. With the increase in demand, possibility...

The equation will be dimensionally correct except sometimes in cases when the right hand side of the equation has more than one term. c. The equation will not be dimensionally correct. d. All constants of proportionality will be correct. C3. How long has it been that scientists have accepted that the nucleus of the atom consists of neutrons and protons? Think of your answers in terms of order of magnitude. a. about a decade b. about a century c. about a thousand years d. since Aristotle C4. Consider the sine of any angle between 30° and 40°. If the angle were doubled, what would happen to the sine of the angle? a. It would double. b. It would more than double. c. It would increase but be less than double. d. In different cases, it could do any of the above. C5. There are other ways of expressing uncertainty besides significant figures. For example, suppose a quantity is known to have a value between 20.4 and 20.0 and our best estimate of the value is midrange at 20.2. We could write the number as 20.2 +/- 0.2 and say that the number has a 1% uncertainty. We would...
