The purpose of this lab was to find my and my fellow classmates resting heart rate and record it. There were seven people in the class and we all participated in this study. There are four places to check heart rate and they are in your wrist‚ the inside of your elbow‚ the side of your neck‚ or the top of your foot. Everyone used the wrist or their radial artery. We used our middle and index fingers to gently feel for the radial artery in each others pulse. I then counted the pulse for 10 seconds

Transfer of Food Preference in Rats after Initial Taste Preference ---------- --------------- Abstract Rats are animals known to be neophobic‚ fearful of new experiences and tend to show behaviors of avoidance to eat novel foods. However‚ there are high chances that rats will eat novel foods if they have reasons to expect that the food is safe to consume and not harmful. The social transmission of food preference paradigm (STFP) was tested in 28 male rats that were about 5 months old

Identity theft is one of the fastest growing crimes in the United States. In the year 2014 according to the Javelin Strategy & Research group‚ $16 billion dollars were stolen from 12.7 million identity fraud victims. (Javelin Strategy & Research‚ 2015) Many cases of identity theft usually go unreported and the numbers could be higher according to the USA today which estimates 130 million from about 1 million in the year 2007.

The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between

Cancer in rats reignites GM food debate A new study has reignited the debate over the long-term health effects of eating genetically modified food. Published in the journal of Food and Chemical Toxicology‚ results of the study show that rats fed a GM diet over their lifespan suffered mammary tumours and severe liver and kidney damage. Advocates of the study say Australia’s regulatory bodies should act on the findings‚ but some scientists have criticised the study‚ saying it is seriously
