Effect of Ionizing Radiation on the Germination‚ Growth and Development of Corn (Zea mays L.) Alexis A. Parco BIO30 Group 1 Sec. A-6L September 27‚ 2012 ABSTRACT Corn seeds pre-exposed to 10‚ 30‚ and 50 kiloRads (kR) of radiation were grown in plots for almost 7 weeks. Four different setups – 10kR‚ 30kR‚ 50kR and the control‚ each with 10 corn seeds initially planted – were observed three times a week (during Mondays‚ Wednesdays and Fridays)‚ and the height of each growing corn was

countries produce more than is absorbed by their domestic economy so they export the surpluses. Either of these actions means that a nation is going to have a trade deficit or a trade surplus. Thus‚ this work is done to examine and find out how the growth of National Income can be affected by trade balance. STATEMENT OF PROBLEM Every country wants to be just an exporter of goods and services. But since no man is an island‚ no matter how much exports a country makes‚ it still has to import at some

THE EFFECT OF INCREASING THE CONCENTRATION OF DETTOL ANTISEPTIC LIQUID ON THE GROWTH OF E.COLI Background: Escherichia coli are rod shaped‚ gram negative bacteria often found in the gut of humans and other warm-blooded mammals (Jacques & Ngo‚ 2004). It is transmitted primarily through faecal contaminated food and water. Most strains of E. coli are not harmful to humans‚ however some strains are pathogenic and can cause symptoms including diarrhoea (Unknown‚ 2012). The active ingredient in Dettol

The Effect of Different Colored Light on Plant Growth Results I measured each plant on days 7‚ 9‚ 11‚ 13‚ 15‚ 20‚ and 32‚ after planting. The plants under the green cellophane grew the most in every measurement. The biggest growth spurt for the plants under the green cellophane was from day seven to day nine. By day 13‚ the plants under the purple and red cellophane started to grow at similar rates as compared with those under the green cellophane. By day 32‚ the plants underneath the green

Title: Studying the Effect of types of Food on a Betta Fish’s growth Introduction: Before you consider buying an animal or pet for the first time‚ you should probably to some research on that animal as we did. It’s very important to know what they eat‚ their environment‚ and also what you shouldn’t do for the health and safety of your fish. For instance‚ our fish cannot eat regular goldfish food. We wanted to test out how the types of food effect the growth. As a control‚ we went for something

An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two
