population is predicted to be up to 11 billion people. The question that comes to mind is‚ “How will we feed a growing population and continue to maintain sustainable food production‚ while keeping waste to a minimum and how will affect developed and developing countries?” World hunger affects about 795 million people‚ and the vast number of the hungry in the world live in developing countries‚ but it also affects developed countries as well. Two possible solutions to feeding the growing population is

A stopwatch was used to monitor how long the reaction took to complete. There are two areas for error by using a stopwatch‚ the first is human error of not being able to stop the timer as soon as the solution changes colour and the second is having to estimate when the solution has fully

An investigation how sugar solutions of different concentrations affect osmosis. Research Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution to one of a higher concentration. If a solution has a low concentration then the amount of (in the case of my investigation) sugar‚ the solute‚ will be low and the solution will be weak. If there is high amount of sugar then the solution will be concentrated (have a high concentration). When two solutions

Heart rate is an extremely important part of many people’s lives. It affects our personal health and how our body works. When the body exercises‚ the heart rate goes up and when the body is inactive or not being active the heart rate goes down. When the pulse is pumping fast‚ then that means work is being done. Having a high heart rate is good for the heart and the body. Obese people can use heart rate and exercise to change their life. Due to the amount of people that are obese‚ a good amount of

The purpose of the experiment conducted was to observe if a higher concentration or lower concentration gradient would affect the diffusion rate of the iodine moving through the starch concentration. This was shown to be an accurate experiment as with a higher concentration gradient the diffusion that did occur happened a lot faster and diffused more efficiently compared to no iodine solution and just water. This is due to the molecular collisions speeding up the experiment in the time period given

Gadgets: As a Cause of Low Grades of Secondary Students Pearl Angelique A. Causing RESEARCH Ms. Michelle Pardillo January 12‚ 2014 INTRODUCTION I. Background of the Study: Students nowadays use gadgets to help increase their grades. But what if these gadgets even help them lower their grades? I conducted a study to find out if students who use gadgets more often have lower grades than those students who use gadgets less frequently. Gadgets have two effects to students: the positive effect

Enzyme Activity How does temperature affect enzyme activity? In this practical investigation‚ my aim is to discover how temperature will affect enzyme activity‚ by looking at the rate of reaction. I predict that the higher the temperature will be‚ the faster the reactions take place. However‚ I also think that there will be an optimum temperature‚ at which the reaction will work at its fastest; if the temperature goes beyond that‚ the reactions will stop altogether as the enzymes would have
