three factors. Firstly‚ in the cell membrane‚ there are sodium potassium ‘pumps’ crossing the membrane which are proteins that bring 2 potassium ions into the cell‚ for every 3 sodium ions it pumps out. As well as this‚ there are protein channels which allow potassium ions in the cell to flow out via facilitated diffusion. Potassium diffuses out the cell much more readily than sodium diffuses in. Lastly there are many negatively charged organic anions such as some amino acids inside the cell. These

external factors which can have an effect on a child’s normal pattern of development. A child may have a physical disability‚ be hard of hearing or have restricted eyesight. This can have an impact on how a child develops emotionally‚ physically‚ intellectually and socially. They may have a learning disability‚ which means they will not develop at the expected rate intellectually or their communication and social skills may not follow the normal pattern of development. A child may have health problems

fundamental unit of the nervous system. These neurons work together with other excitable cells to produce action potentials when they receive electrical or chemical stimuli. Action potentials can be thought of as an “all-or-nothing” event and occur as a large-scale depolarization when sodium and other positive ions rapidly enter the neuron through membrane channel proteins. Once initiated‚ action potentials travel down the length of the axon and when it reaches the end a neurotransmitter is released into

Social and Behavior Patterns of Meerkats The animal that I selected to observe is the meerkat. This research paper will explain the behavior patterns and social structures of the meerkat. After touring the entire zoo‚ I selected the meerkats because they were more active than any other species and their location was closer to view than any other animal. The weather was cloudy and warm and it was about 1500 hours when I arrived at the site to observe them. Meerkats have long bodies and faces

electricity. There are leads attached to an amplifier within the machine‚ which must be clipped to the edge of the electrodes. The ECG is recorded from 12 different electrode sites. The amplitude and the shape of the signals depend upon the position of the electrodes (Brown‚ 1999) (Conover‚ 1992). The SA node produces the pacemaker potential and if this reaches the threshold then an action potential is generated. There are five stages involved during cardiac action potentials‚ during these stages
