Temperature and Reaction Time
Age and gender of a person have a slight effect of the body`s temperature. Due to the fact as you age your body finds it harder to control the core body temperature, meaning you could be less aware of yourself overheating or have a lessened realization/awareness of a sudden drop in your body's temperature . A newborn baby can also have difficulty with core temperature and could be high one moment and low the next , but after one year the baby ages and starts to develop, the temperature will become normal. The affect of gender with core temperature is slight , but it's still there and could be useful to know if someone is actually running a fever or not. Taking data from an experiment conducted by Carl Reinhold August Wunderlich who examined over a million temperatures taken from the armpit he deduced the normal , or “average” body temperature for an adult was 98.6 degrees fahrenheit , and saw that woman had a slightly

The last one was taken at 12 PM , where the patient had a reaction time of 23 seconds which was the fastest through the day and the average body temperature, which was warmer than the temperature taken at 4 AM ,(98.4 degrees). So in a simpler way of inputting it if a person is colder , their reaction time will be slower , but if warmer it will be quicker. Outside temperature , (which can affect core), will affect reaction time. Generally muscles will become more flexible when it's warmer , rather than it to be colder. While it's warm there will also be increased blood flow, which causes more oxygen to the muscles. So , as said before that will affect reaction time if a person is warmer or

When the subject submerged their face in 25 degree water, their heart rate decreased. It did not decrease very much because the water was at room temperature. It decreased more at 15 degrees and even more at 5 degrees. This was expected to happen because the diving reflex took place. The cold water puts the body is oxygen conserving mode and restricts the blood in your extremities. This is what reduces oxygen consumption which eventually lowers the heart
...n Article Nielsen et al (2013) Diagnostic Accuracy hierarchy methods is applied which is review on second level (II) i.e. Randomised Controlled Trial and Meta-Analysis in the Pyramid level. These are also considered as gold standard in hierarchy of research design for evaluating the safety of a treatment. Also therapeutic study method is applied where different patients of age groups are used to treat with two different temperatures. There are two different trial methods used in this study. Here the level of hierarchy is high so that we can trust the result based on the data provided. We can also provide and opportunities to collect useful information about adverse affect such as temperature control over cardiac arrest. In the Meta-Analysis method multiple treatment groups are been treated with each other. There is also observational study performed in the article.
Animal metabolism consists of the utilization of nutrients absorbed from the digestive tract and their catabolism as fuel for energy or their conversion into substances of the body. Metabolism is a continuous process because the molecules and even most cells of the body have brief lifetimes and are constantly replaced, while tissue as a whole maintains its characteristic structure. This constant rebuilding process without a net change in the amount of a cell constituent is known as dynamic equilibrium (Grolier1996). In the combustion of food, oxygen is used and carbon dioxide is given off. The rate of oxygen consumption indicates the energy expenditure of an organism, or its metabolic rate (Grolier1996).

How Temperature Affects the Rate of Reaction in the Reaction of Magnesium and Hydrochloric Acid
= The results that I have gathered from my experiment I have put into graph form. From my results I have found out that the more I exercise the longer I exercise the longer it takes for my pulse to return to normal, I think that I did not reach my potential maximum heart rate because the exercised was not strenuous enough for my body. I also discovered that when taking my pulse it takes a few seconds for the strong pulse to get back to the surface.
Effect of Temperature on the Rate of Reaction between Sodium Thiosulphate and Hydrochloric Acid Investigation Chemical reactions are used in our everyday life, they literally keep us alive. They are used in food, respiration and everywhere else in the environment. A chemical reaction mainly occurs when reactants react together to produce a new product. The speed at which this reaction takes place is called the rate of reaction. The product produced has a number of particles in the solution that has formed from the reactants.
The pH of the solution would alter the rate of the reaction if it was
The limitations to this vital sign though are to understand and know the different types of thermometers. Many aspects can affect temperature such as exercise, age, stress and surrounding weather and environment. It is important to make sure the patient is relaxed and hasn’t been doing strenuous activities shortly before being assessed (Berman, 2015) . For a healthy adult, the normal body temperature should be around 37°C. Anything over that is considered a fever (Martha Keene Elkin, 2007). Similar to the other vital signs though, everybody is different and someone might have a slightly higher or lower temperature which is normal for them. There are many different types of thermometers. There are oral, rectal, chemical, tympanic and temporal artery thermometers as well as more (Berman, 2015). Depending on the person, different thermometers are used. Aspects such as being a child, not being able to move, being asleep while your temperature needs to be taken can all affect which type of thermometer a health care professional uses. For example, if a patient is asleep then it is very invasive to use an oral thermometer because you would have to open their mouth and then if they wake up they would feel very violated. My worry about taking temperature is which thermometer to use or if I could just use any. The difficult part was finding out whether there were special circumstances to use certain

The Effect of Temperature on the Rate of Reaction Between Sodium Thiosulphate and Hydrochloric Acid
In a similar case as with the brain, this causes greater sensitivity to slight changes outside of the body. Doctors are also looking at factors like age and race to see if any discrepancies arise across demographics. For example, current research shows that in general younger women affected by menopause are more likely to experience night sweats than older women, with percentages decreasing with age. Similarly, studies have shown that Asian women are the least likely to experience night sweats as a symptom of menopause.
