Practical 1: Observation of mitosis in garlic root tips Introduction The practical will involve the preparation‚ observation‚ and classification‚ of the various stages of mitosis by observing garlic root tips using a microscope. The study comes under the heading of cytogenetics which is the visual characterisation of genetic material and the study of how that material reacts during the life of the cell. Strictly speaking‚ mitosis is the division of the nucleus into two daughter nuclei that are

Trial # Guess Observation Explanation Trial 1 The dyed red water will not seep into the blue cold water. My guess was indeed correct and red water did not interfere with the blue water. Because the molecules in the blue water are much closer together because its cold and well the red water has warm/hot water and the molecules are everywhere. The molecules in the blue water are so dense that they’re making a layer so that the molecules from the red jar do not come through. Trial 2 I think

Questions and Problems: 1. Describe the type of meter movement used in analog meters. The current in the circuit is used in basic meters to measure the voltage drop or current in the circuit. The current passes through the coils of wires‚ which is then magnetized. Inside the apparatus‚ there is also a permanent magnet which opposes the magnetic field of the magnetized coil of wire that is connected to the pointer therefore‚ as we see in meters‚ the pointer moves. There is also a spring connected

Hypothesis If we test the amount of electrolytes in an energy drink and orange juice‚ then orange juice will have more electrolytes than an energy drink. Variables Independent Variable- the two different drinks‚ orange juice and an energy drink Dependent Variable- the amount of electrolytes in each to determine whether or not one has more than another Controlled Variable- same multimeter‚ same brand and type of alligator clips leads‚ same gauge‚ length‚ and brand of copper wiring‚ same brand

Stanford Prison Experiment Following the American Psychological Associations guidelines Zachary Hudson Waterford District High School Abstract The Stanford prison experiment‚ an unethical experiment created to study human nature in the most hellish of environments. Regular students were deceived into applying for the experiment itself and later regretted the choice because of the events that occurred during the short time that experiment ran in. The experiment ran and quickly

Behavioural Study of Obedience: Milgram’s Experiment M.J George Brown College #1) Obedience I think the three aspects of the situation faced by the subjects in Milgram’s study were the prestige of the university‚ the proximity of the experimenter‚ and the money paid. These aspects were the most influential in causing the subjects to obey. The influence of the prestige of Yale University was a key point to get the obedience of the subjects. People are prone to obey more

Medical Experiments of the Holocaust As a society we place those in the medical profession on a pedestal. They are people to be looked up to and admired. In many ways they are Gods‚ right here with us on earth. People put the hope and faith in doctors hoping they can perform miracles. Throughout history‚ doctors have indeed preformed many wonders. There were‚ however‚ some doctors that betrayed this belief and peoples trust. These doctors could be found in concentration camps such as Auschwitz

Phillip Zimbardo’s Stanford Prison Experiment: Ethical or not? Chase Clark University of Massachusetts‚ Lowell Abstract The research conducted in this paper consists of solely the Stanford Prison Experiment‚ which was originally conducted by the social psychologist‚ Phillip G. Zimbardo. This experiment replicated a real prison that took students to participate in it. Students role-played the prisoners themselves‚ and prison guards. It was conducted in the basement of the psychology department
