Abstract: The purpose of this experiment was to examine how the compound action potentials propagate down the sciatic nerve of a frog based on varying stimuli. Before the nerve could be tested it needed to be extracted from the thigh of the frog and then submerged in saline. Several varying stimuli were used and recorded by a software package. The second experiment requires a constant stimulus with varying reference pin locations. From this the velocity of the action potential propagated can be

Experiment No. 1: MELTING POINT AND BOILING POINTS OF ORGANIC COMPOUNDS ABSTRACT The properties of organic compounds depend on their chemical structures. Intermolecular forces of attraction affect physical properties such as melting and boiling point. Through the Thomas Hoover apparatus‚ the melting point of 8 test compounds was determined. Salicylic acid exhibited the highest melting point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting

Paradox A statement that appears to be self-contradictory or opposed to common sense‚ but upon closer inspection contains some degree of truth or validity. The first scene of Macbeth‚ for example‚ closes with the witches’ cryptic remark “Fair is foul‚ and foul is fair….” Parallelism Similarity of structure in a pair or series of related word‚ phrases‚ or clauses. The basic principle of grammar and rhetoric demands that equivalent things be set forth in coordinate grammatical structures: nouns

Cox’s words here relate to my belief that getting a head start on the career you strive for is important and should always be taken into thought and consideration. When

In our crowded cities it has become difficult to move easily and rapidly from place to place‚ especially when driving a car or taking the bus. Cycling can be a good alternative to the other means of transport‚ but it has also some disadvantages that we must be taken into account. First of all‚ the major advantage of cycling is its cost. A bike doesn’t need petrol or‚ unlike the bus‚ the purchasing of a ticket. Neither does it need a lot of maintenance‚ unlike motorized vehicles which must be

The Effects of Secondary Plant Compounds on Lumbriculus Variegatus Heart Rate Introduction Blackworms (Lumbriculus variegatus) were used in this experiment to study the effects of secondary plant compounds‚ chemical compounds produced by plants that are not part of the general metabolism‚ on pulse rate. Secondary plant compounds act as defense mechanisms which reduce or eliminate consumption of some plant species or even attract predators. These compounds are not essential to the plant but often

Writing has never been my favorite activity. Before this class I took English Composition class in Hocking College and I had chance to write several essays about different topics. Before Hocking College I never had written an essay in English language. So going into research class did make me a little nervous. As a middle aged women ‚ out of school for 20 years and English as a second language I am probably have a little disadvantage compared to the other kids ‚ fresh out of highschool but I welcome
