2. Considering the nervous system‚ please briefly explain how the electrically excitable membrane changes its electric potential. In other words‚ how is the cell membrane excited? At the surface of the cell membrane‚ there are three classes of gated channels exist‚ chemically gated or ligand-gated channels‚ voltage-gated channels‚ and mechanically gated channels. Originally‚ at the resting membrane potential‚ most of the gated channels are closed. However‚ when these gated channels open‚ the movement

“The Charge of the Light Brigade. Throughout the poem‚ Tennyson uses strong imagery and metaphors to help describe the dangers that the Brigade faced‚ which explained the reason to honor the Brigade for their victory. Tennyson’s repetition of statements and words puts emphasis on certain lines. The uses of imagery and repetition of statements and words help display the main idea. The main idea of the poem is that the determination and strength of these soldiers in the face of danger are admirable

Introduction and Experimental Goal: An electric field surrounds all electrically charged particles. With electric fields‚ one can determine the effects of all of the charges in the environment. In this lab entitled “Electric Fields and Potential Mapping”‚ the main goal obtained was to examine and deliberate the effects of an electric field and electric potential. Examples of some effects of electric fields include resultant forces‚ changes in motion‚ changes in current flow‚ etc. By using conductive

THE RELATIONSHIP OF ELECTRIC FIELD INTENSITY AND ITS DISTANCE FROM THE CHARGED OPOINT PHYS-232 JIANSONG HE GROUP: Abstract This experiment was performed to find the electric field strength from different distance to the charged point. The field strength was determined statically‚ by measuring its electrical potential when subjected to loading‚ and dynamically‚ by measuring the electrical potential at different location on the conductive paper. The electrical potential was measured from three

Hypothesis: Our purpose for this project was to find out what fruits and vegetables could generate an electric charge. We also wanted to find out which ones had the greatest and least charge. Our hypothesis stated that the potato would have the greatest charge. II. Methodology: The materials we used for this project were the fruits

I. Physical Features Electric eels are not really eels‚ they are actually ostariophysians‚ but have a strong physical resemblance to true eels. . An electric eel is mostly tail. The internal organs are compressed into the anterior (front) 1/5th of the body‚ and the rest of the fish consists of the long‚ electricity-producing tail. The tail contains the electric organs: Sachs’ organ‚ Hunter’s organ‚ and main organ. Extending down the entire tail region is an elongated anal fin. There are no dorsal

Analysis: “Government Must Lead the Charge on Electric Cars” The Australian government needs to “lead the charge” on the electric car revolution‚ according to Megan Flannery. She writes this in response to a feature in a national newspaper. Flannery writes her article with a mostly matter-of-fact tone‚ which is also formal. She uses facts and evidence to support her argument; she also includes persuasive‚ emotive and inclusive language to influence the reader’s belief on this issue. Her article is

The electron is a fundamental subatomic particle that carries a negative electric charge. It is a spin-½ lepton that participates in electromagnetic interactions‚ and its mass is less than one thousandth of that of the smallest atom. Its electric charge is defined by convention to be negative‚ with a value of −1 in atomic units. Together with atomic nuclei‚ electrons make up atoms; their interaction with adjacent nuclei is the main cause of chemical bonding. The name "electron" comes from
