the essential components of the research study. There will be a decrease in temperature in the newborn if having difficulties breastfeeding while having skin-to-skin contact with the mother. That was the inferred hypothesis. The method used to gather the information was a pretest-test-posttest study design and the sample consisted of 48 full-term infants. The key findings showed most infants reached and maintained temperatures between 36.5 and 37.6 degrees Celsius‚ the thermo neutral range‚ with only

MIP experiment on the melting temperature of different polymers 8.1 Compare and comment on the results obtained. LDPE has the lowest average melting temperature (103.6°C) out of the 4 polymers. It is because LDPE is a linear polymer that has a branched structure which is able to expel the applied heat faster through the “branches” and melt faster. HPDE has the second lowest average melting temperature (139.5°C) out of the 4 polymers. Unlike LDPE‚ HDPE does not have a branched structure and the

Effects of the Bottleneck and the Founders effect Cecil Smith GS102 Grantham University Online The bottleneck effect happens when something of a great devastation has happened‚ causing a great amount of people to lose their lives and leave behind very few people at the most. The bottleneck effect happens at random and can kill of a whole population and with it can also wipe out the gene pool by doing so. An example of the bottleneck effect would be something like a tsunami‚ or an earthquake‚ which

combined with baking soda. Then the temperature was taken‚ and finally calcium chloride was added‚ which formed a chemical reaction. Our lab question was how does the amount of calcium chloride affect the temperature of the product? We chose our independant variable to be the amount of calcium chloride added to the water/baking soda mixture. We had the dependant variable be the ending temperature. My hypothesis is IF we add more calcium chloride‚ THEN the temperature of the product will rise‚ BECAUSE

Is There A Relationship Between Body Temperature and Heart Rate? Statement of Research Question: This study sets out to determine whether there exists a difference in the average body temperature between males and females. Furthermore‚ the study aims to determine whether an increase in heart rate corresponds with an increase in body temperature. Data Collection: The data was obtained from the article “What’s Normal? -- Temperature‚ Gender‚ and Heart Rate” (Shoemaker‚ Allen 1996) as found in

rate. The hypothesis also proposed that as temperature increases the speed of the reaction would decrease‚ this is evidenced in graph 7 which shows a negative decrease in time as the temperature of the solution increases. This decrease can be modelled by the exponential formula T=12.9e-0.0249t. The raw data collected suggests that directly increasing the concentration of potassium iodate decreases

As the temperature increased‚ the enzyme activity also increased‚ however‚ only to an optimal level which was at temperature 32oC. Once the temperature was beyond the optimal level‚ the rate began to decline and this was represented by the concave curve on figure 5 and 7. This was because as the temperature increases‚ the frequency of collisions between the enzyme and the substrate also increased hence faster reaction rate. Whereas‚ the enzymes operated slowly at low temperature as there wasn’t sufficient

In virtually any art form‚ color temperature can be manipulated in a way that evokes certain moods and feelings to the viewer. These two paintings are a perfect example of how color temperature can interpret the same subject in several ways. André Derain’s The Houses of Parliament from Westminster Bridge‚ 1906 displays a distinct warm temperature that is interwoven with cooler tones. At a first glance‚ the red‚ yellow‚ and green that dominates the painting tells us that it is indeed on the warm end

are organisms that have a limited ability to control their body temperature. Their cellular activities generate little heat. Their body temperatures rise and fall with ambient temperature changes. Most organisms are ectotherms. Examples are plants‚ all invertebrates‚ fish‚ amphibians and reptiles - ENDOTHERMS are organisms whose metabolism generates enough heat to maintain an internal temperature independent of the ambient temperature. Examples are birds and mammals - EXTENSION (Not really needed
