Question

Design a logical circuit using AND, OR and NOT gates to evaluate ABC+BCA.

Answer 1

Explanation:

• A short circuit is the instrument that is placed on the local apparatus. There will be low resistance of such circuit and by a local battery, its current is provided, q. v. By the current form, its actions are determined from the main line tossing its battery in and out of circuit by some equivalent or relay.

• One part of the neurone occurs in an action potential. There will be the diffusing of Na+ ions into the neurone across the plasma membrane. So, when the channels are open, the concentration of Na+ increases in the neurone.
• There will be sideway diffusion of Na+ ions from the high concentration area (area A) down a concentration gradient where there is an action potential to the low concentration areas (B and C).
• The diffusion of Na+ ions to the area B ahead of the action potential and to area C that is behind the earlier action potential, as there will be lower concentration of "resting" areas with lower concentration of Na+ ions than area A. This movement is called the local circuit. $\begin{aligned}&\mathrm{x}=\mathrm{ABC}^{-}+\mathrm{BCA}^{-}=\mathrm{A}\left(\mathrm{B}^{-}+\mathrm{C}^{-}\right)+\mathrm{B}\left(\mathrm{C}^{-}+\mathrm{A}^{-}\right)=\mathrm{AB}^{-}+\mathrm{AC}^{-}+\mathrm{BC}^{-}+\mathrm{BA}^{-}=\mathrm{AB}^{-}+\\&\mathrm{C}^{-}(\mathrm{A}+\mathrm{B})+\mathrm{BA}^{-}\end{aligned}$
