4-METHODOLOGY 4-1 Study design The design of our study is a type of case-control design‚ where the induction of apoptosis on both the myeloid (K562) and lymphoid (Jurkat) human cell lines by kola nut extract will be investigated. The design of the experiment will include a control group of cells (untreated and treated with only solvent that is used in the extraction

Psychology Experiment No. 2 Effect of Inconsistency of Objects in Scenario on Perception Introduction: In our everyday lives‚ we are used to seeing objects within their particular characteristic scenarios. For example‚ it is nothing to wonder if we see a person browsing the internet in a computer lab or a car speeding on a road. However‚ when we see an object which is inconsistent with the environmental setting‚ we do feel alarmed. Thus‚ it is shocking for us to see someone working on a

Introduction In physics we must distinguish between vector quantities and scalar quantities. Vectors are quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude. Although a vector has magnitude and direction‚ it does not have position. That is‚ as long as its length is not changed‚ a vector is not altered if it is displaced parallel to itself. In contrast

We hypothesized that the presence of hairiness is inherited as a dominant trait and follows basic inheritance laws. The experiments were performed in quads‚ with the different quads

Dr. Heidegger’s Experiment 5a) The narrative point of view in the story is third person omniscient. This point of view suits the story because; the story catches all the thoughts and emotions of the characters that experience youth through the “fountain of youth”. The narrator seems to be above all the characters‚ expressing how their presence contributes to the storyline. 5b) The external references are people with an outside perspective or background characters that supports the story

The problem for this experiment is how does the amount of caffeine affect the speed and performance of a mouse. The hypothesis is if the amount of caffeine consumed by the mouse is increased‚ then the time at which the mouse completes a set obstacle course will decrease when time is a function of caffeine quantity. The amount of caffeine consumed by the mouse before completing the obstacle course is the independent variable. The dependent variable of the experiment is the amount of time the mouse

Experiment 1 Calorimetry Chem 17 Univerity of the Philippines Diliman Discussion All chemical reactions involve energy. By understanding the behavior and connection of energy flow within a chemical reaction‚ we can understand and manipulate them to our advantage. The most common form of energy observed during chemical reactions is heat. The reaction may absorb (endothermic) or release (exothermic) heat‚ depending on the reacting substances. Calorimetry is the process of measuring the heat flow

researchers will be conducting the studies with respect to the subject’s natural rights as a human being. History shows us that medical studies have not always been conducted this way. The Jewish Chronic Disease Hospital‚ The Tuskegee Syphilis experiments‚ and the Hepatitis studies at the Willowbrook State School‚ are a few examples of highly unethical research studies that have previously been conducted. Willowbrook State School may be one of the hardest to consider ethically‚ because it involved
