The Feeding Behavior of the Protist known as Tetrahymena vorax Abstract The purpose of this experiment was to study the rate of phagocytosis of the specific protist known as Tetrahymena vorax. This certain kind of protist feeds at a normal rate when conditions are normal. We began the experiment of understanding how Tetrahymena feeds at normal temperatures. Doing so‚ we allowed the Tetrahymena to feed at specific time limits and then killed the protist with gluderaldheyde to detect how much

Once the experiment was over the results showed that the head end was able to retain the learning by classical condition better than the tail end could. There were more positive reactions with the head compared to the tail. It was not a drastic difference‚ but the head it was able to retain the learning slightly better than the tail end did. Not everything goes as planned so there were some experiment where the planarian was lost or it died. Some planaria did not retain the information before it

The use of animals to test human drugs and cosmetic products and to conduct pointless laboratory experiments is unconventional. Humans and animals are similar‚ but they are not identical‚ so using animals to test products intended for humans does not make sense. Each year millions of animals are killed or badly maimed in laboratory experiments. Animal testings must be banned. The tests are usually proven to be ineffective‚ they waste tremendous amounts of money‚ the tests are cruel‚ and there are

cold or flu. In order to see if using anti-bacterial gels prevents getting the flu or a cold an experiment must be performed with the teachers. The experiment must be properly performed by randomly dividing the teachers into groups so that outcomes are not altered by race‚ age‚ or sex. The experiment breaks down as follows : The Hypothesis A hypothesis is an educated prediction of an experiment based on the factors. In this case it is my hypothesis that using anti-bacterial will help prevent

in both experiments the participants were paid volunteers and had to give an increasing punishment. The Dutch experiment was conducted in a natural experiment though and and Milgram’s one - in a university. The results of both studies support each other’s findings. The difference in the level (percentage) of obedience found can be explained by the difference in the type of punishment. 65% of the participants completed Milgram’s study and 92% completed Meeus and Raaijmakers’ experiment.

Experiments concluding of tests that test capabilities of humans physically and mentally‚ to observe how much the body reacts to drugs‚ chemicals and much more. Experiments that are physically painful‚ as well as torturous to the subject participating in the event. Many of these portrayed experiments seem quite extreme to become a reality‚ however there are many reported

evaluation of a person and how we perceive their attributes. The hypothesis of this experiment is one tailed. A person who is perceived as being more attractive will have be given positive personality traits‚ a person who is less attractive. The null hypothesis is that people’s perception of attractiveness will not affect their judgement of that individual’s personality traits. The method that was used was experiment and the design used was independent groups. The Independent Variable is a photograph

freezing popcorn yield more popcorn? Project Design Plan. This scientific experiment is to gauge the amount of kernels popped when the storage temperatures of the kernels are changed. Does freezing popcorn kernels for 24 hours yield more or less popped kernels than popcorn kernels stored at room temperature? By performing this experiment we can decide how to maximize our food potential. We will purchase six identical brands of popcorn from the local food

Lab Reports gives the explanation of the experiment done Lab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report‚ use that. Here ’s a format for a lab report you can use if you aren ’t sure what to write or need an explanation of what to include in the different parts of the report. A lab report is how you explain what you did in experiment‚ what you learned‚ and what the results
