A graded potential in physiology‚ is described as local changes in membrane potential that occur in varying grades or degrees of magnitude or strength. When compared to graded potential‚ an action potential is described as brief‚ rapid‚ large (100mV) changes in membrane potential during which the potential actually reverses so that the inside of the excitable cell transiently becomes more positive than the outside. As with a graded potential‚ an action potential involves only a small portion of

Industry Structure and Skill Set Individual Report The JICS‚ or the Joint Industry Committee‚ are all the main media surveys. They are made up of media owners‚ media agencies‚ professional bodies and clients. The media owners pay the largest sum of the cost of running the JICS as it is their media that is being analysed. The JICS main role is media measurement‚ which is when media owners and agencies calculate how many of a given audience a medium can reach at any given time. The BARB and the NRS

‘Growing Up’ The Instant noodles market in India is finally coming of age after over 25 years The instant noodles category in India was‚ in a sense‚ created by Nestlé with the introduction of their Maggi brand in mid-1980s. The concept of ‘2-minute noodles’‚ positioned as a quick snack option for children‚ found acceptance with both the children and their mothers as well. Having built and nurtured the category’s evolution‚ the brand name “Maggi” almost became a synonym for the instant noodles

Industry structure affects intensity of competition in the following ways: Opportunity potential – Profitable market is likely to attract firms to invest in available opportunity‚ the more the number of firms in the market‚ the more intense of the competition. Ease of entry – When entry into an industry is relatively easy‚ more firms are likely to invest in that. ‚ including some marginal ones‚ are attracted to it. However‚ committed members of the industry may adopt strategies to discourage potential

The formation of an action potential can be divided into five steps. (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached‚ all Na+ channels open and the membrane depolarizes. (3) At the peak action potential‚ K+ channels open and K+ begins to leave the cell. At the same time‚ Na+ channels close. (4) The membrane becomes hyperpolarized as K+ ions continue to leave the cell. The

THE WORK DONE BY A CONSERVATIVE FORCE ALWAYS HAS FOUR PROPERTIES: 1. It can be expressed as the difference between the initial and final values of a potential-energy function. 3. It is independent of the path of the body and depends only on the starting and ending points. 2. It is reversible. 4. When the starting and ending points are the same‚ the total work is zero. The total mechanical energy ME = K + U is constant. Object moving in a uniform gravitational field gravitational a

which cell has the larger resting membrane potential? Explain. If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2. Predict the effect of a reduced extracellular concentration of Na+ on the magnitude of the action potential in an electrically excitable cell. If there
