How does stress affect the immune system The immune system is designed to defend the body against millions of antigens that would otherwise invade it. None of these things are able to get in when your immune system is working efficiently‚ but the moment your immune system stops functioning properly‚ the opportunity for antigens to attack is available. Kiecolt-Glaser (1984) carried out a natural experiment investigating whether the stress of short-term stressors had an effect on immune system functioning

the following questions: How does stress affect the policing community? Stress has many effects on the policing community as a whole. Officers may lose sleep over the stress and become fatigued which in turn causes them to lack on their duties‚ or delay their reaction time. Officers may also get so stressed that they go through a post traumatic disorder. Post traumatic disorder can cause officers nightmares‚ or worse they can wind up committing suicide. How does police culture support police

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

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

Therefore theyare most likely to move at a rate which is inaccordance with the external temperature. This correlation‚ between temperature andmovement‚ is what this experiment aims to determine. Spearman’s Rank Correlation is a nonparametric measure of statistical dependence between two variables. It assesses how well the relationship between two variables can

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

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
