Does age affect reaction time? Aim: To find out if age affects reaction time through the use of an online program created by Human Benchmark Background information: in a study conducted by the University of Michigan‚ the most accepted theory for the effect of age on reaction time is that older people have a slower reaction time in comparison to people of a younger age. This is because adrenaline levels and reflexes are in best condition when young. Another reason of reaction times decreasing with

A reaction is a chemical process in which substances decomposes‚ or combines with other substances. In this case it is synthesis chemical process which creates new products. However‚ the rate of a reaction can be altered either faster or slower depending on certain variables. These variables are concentration‚ temperature‚ surface area‚ and catalysts. A reaction can be made faster or slower with a variation in the concentration of reactants; a reaction goes faster when there is an increase in concentration

The Stamp of One Defect “To know a man well were to know himself” (5.2.139)‚ the definition of a foil in Hamlet’s own words. In literature foils can be used to contrast and highlight specific qualities of the protagonist or other main characters. Hamlet has many foils throughout the play‚ which help to aid in the understanding of Hamlet’s character and his motivations. However‚ three characters in particular‚ Laertes‚ Horatio and the First Player play key roles in how Hamlet ultimately takes his

Jared Choy Mr. Dahlhausen Period 6 17 November 2014 Does Age affect Reaction Time? When a person sees a health care provider and the doctor hits the person’s knee with a rubber mallet‚ the person’s leg kicks up on its own. This happens because when the doctor hits your kneecap‚ the tendon under it gets stretched‚ which in turn will send a signal to an awaiting motor neuron so it can command the muscle to contract. Let’s take for example the reflex arc. A reflex is the involuntary movement of the

time it takes for the cross on the bottom of the beaker while the reaction is recurring to disappear. As it can be seen in the graph‚ the higher the temperature the shorter the time is for the Sulphur to be created. If it is looked as one continuous line‚ the first part of the trend line shows a steep‚ straight and constant decrease; then the 2nd part is not as steep and has a more gradual decline. Moreover‚ it shows how a reaction at 20°C a slower time for the cross to disappear compared to 40°C

Organic food is defined as produce (animal and plant) that is grown without the aid of any chemicals or pesticides‚ this means the animals are fed organic feed and the plants are grown in a very different way to most foods we see at the supermarket. Many people purchase organic food because they think that the nutritional benefits will make up for the extra money that you spend. Lots of people say that the manufacturers of organic food lie to us when selling these products‚ they say that there aren’t

Spina Bifida comes from the word for “split spine in Latin (Webster‚ 1997). It is a serious birth defect that occurs when the tissue surrounding the developing spinal cord of a fetus doesn ’t close properly. Its part of a group of birth defects called neural tube defects (Spinal Bifida Association of America‚ 2006). The neural tube is the embryonic structure that eventually develops into the baby ’s brain and spinal cord and the tissues that enclose them. In normal circumstances‚ the neural

the temperature the faster the reaction will occur) has been proven correct and it proves the theory right. From the results‚ we can see this‚ as the iced water (10 degrees) had the slowest rate of reaction at 1.10 minutes. Then the room temperature water (19 degrees) was tested and had a slightly better rate of reaction at 1.09 minutes. Then last of all‚ we tested the boiling water (63 degrees) which had a large improvement from the last two with a rate of reaction of 43.5 seconds. This showing development
