Experiment 8 “Lipids” and the purpose of the lab is to become familiar with the properties and reactions of certain lipids called fats or oil. For this lab‚ students are testing the properties and reactions of lipids and soap will be prepared and its properties will be tested. To begin the experiment‚ place 5 mls of water‚ ethyl alcohol‚ chloroform‚ and toluene in to four clean test tubes and add 1 drops of cottonseed oil to each test tube. Shake it and record your observation. To do part B‚ in three

THE ROMANOV FAMILY 1) Hemophilia is a kind of sex-linked disorder. The Romanovs actually have a child with symptoms of hemophilia. It is possible‚ that a family with the same genotypes have no children with hemophilia‚ because in Alexandra’s family this disorder was present then the chance of having a normal child was 50%. This is true each time a child is born to the family. 2) Skeletons can be identified trough few techniques in order to determine the age‚ sex‚ and race of the decedent.

Arlind Mara Paper Towel Lab Report AP Biology 15 September 2011 Which Towel is The Quicker-Picker Upper! To determine which of the most popular paper towel brands such as Bounty and Marcal would be the Quicker-Picker-Upper I conducted the following experiment during which I dipped 6in X 6in squares of paper towels into 100mL and measured the amount of water absorbed by the towels in 20 seconds. After averaging all 3 trials for the paper towel brands that I tested I arrived to the conclusion

The purpose of this lab that was completed was to observe standing wave patterns in clamped strings‚ and understand the effect of the standing wave frequencies of changing the length (L)‚ tension (T)‚ and linear density (p) of the strings. Standing wave patterns in strings are observed at certain excitation frequencies for special values of L‚ T‚ and p. A standing wave can be defined as a vibration of a system in which some particular points remain fixed while others between them vibrate with the

The hypothesis for this experiment was that if the baby lemurs activity level was compared to an adults‚ the baby lemur will have a higher activity level. The hypothesis was not supported. The data shows that the adult had a higher activity level. The data shows the adult being 1.8% more active than the baby lemur. The other behaviors of the adult Ring Tailed Lemur was grooming and sleeping/resting. Second‚ throughout the six trials the only behaviors that were performed by the baby lemur was sleeping/resting
