BIOLOGY PRACTICAL ASSIGNMENT NAME OF INVESTIGATION: Effect of Eutrophication on Plant Growth RESEARCH QUESTION: How does the process of Eutrophication affect the growth of Duckweed? HYPOTHESIS: In this experiment‚ we are basically testing the use of different fertilizers on the growth of Duckweeds. Plants need fertilizers for their growth and to increase the yield of crops. But‚ at the same time‚ it depends on which Fertilizer being used and in how much proportion. Does it have sufficient nutrients

MICROBIOLOGY COURSEWORK The effect of antibiotic concentration on bacterial growth Introduction Null Hypothesis- Increasing the antibiotic concentration has no effect on bacterial growth. Experimental Hypothesis- Increasing the antibiotic concentration decreases bacterial growth. Scientific Theory Bacteria are prokaryotes and can be identified by their shape. Spherical bacteria are called cocci‚ rod shaped bacteria are called bacilli‚ spiral shaped bacteria are called spirilla and

The impact of inflation on the functions of money Money refers to any commodity which functions as medium of exchange or the settlement of a debt. In a modern economy bank notes and coins clearly form part of the money supply as they are acceptable in the settlement of all transactions. Moreover some transactions are settled by cheques drawn on bank deposits in current accounts (also known as sight or demand deposits). Thus current account deposits also form part of money supply. Deposits accounts

The control of inflation has become one of the dominant objectives of government economic policy in many countries. Effective policies to control inflation need to focus on the underlying causes of inflation in the economy. For example if the main cause is excess demand for goods and services‚ then government policy should look to reduce the level of aggregate demand. If cost-push inflation is the root cause‚ production costs need to be controlled for the problem to be reduced. Monetary Policy

The Effects Different Types of Water Have on Plant Growth Abstract This experiment examines the rate of plant growth when watered with different solutions. Throughout the course of a nine week period‚ five lima bean seeds were watered with five different solutions to see which will most enhance the growth of plants. The five solutions consisted of distilled‚ filtered

Effect of Sugar on Bean Plant Growth Abstract The objective: My project was to determine if bean plants grew stronger and healthier by the addition of the right amount of sugar to their watering. I believe that plants that receive 50 grams of sugar per liter of water would help bean plants grow to be stronger‚ healthier and larger because they would get energy from the sugar. Methods/Materials 36 bean plants were grown in potting soil. The same amount of soil was used in each pot and it had no added

The Effect of Vitamin C on Plant Growth Aim: To determine the effect of salt/ sugar/ caffeine/ vitamin C on seed germination. Hypothesis: The plant will grow slowly or die due to the Vitamin C. Equipment: * 2 cups * 2 measuring cups * Water * Vitamin C/ orange Juice * Soil * 4 seed (2 for each cup) * A ruler Method: 1. Pour ¾ of soil into each cup 2. Plant 2 seeds into each cup. Put it about half way down the soil 3. Mix 1mL of orange juice with 5mL

Effect of Clay in Soil on Plant Growth INTRODUCTION: In this experiment‚ the relationship between the amount of clay in the soil and plant growth was measured over a two week time period. The manipulated variable in the experiment was the amount of clay in the soil‚ specifically one hundred and twenty grams of clay mixed with eighty grams of soil‚ and the responding variable was the plant growth. Although clay in soil can be beneficial for plant growth in the sense that is provides good moisture

Economic Effects In October of 1973‚ OPEC announced that it would increase the price of oil by 70% by cutting production by 25% and a production cut of 5% each month after (Yurgin). At the time‚ oil was selling for $3. This shock caused the price to increase to $5.12 (Reid). Two days after this initial shock‚ the price increased again to $11.65. This would cause a new aggregate supply curve left of the original supply curve (decrease in supply). This didn’t have a great effect on demand because
