    the ability to respond to stimuli and convert them into nerve impulses‚ and conductivity‚ the ability to transmit an impulse (in this case‚ to take the neural impulse and pass it along the cell membrane). In the resting neuron (that is‚ a neuron that does not have any neural impulses)‚ the exterior of the cell membrane is positively charged and the interior is negatively charged relative to the outside. This difference in electrical charge across the plasma membrane is referred to as the resting

    Transport System of Organisms Problems faced by Multicellular Organisms: a)Big size-the total surface area to volume (TSA/V) is decreased . Rate of diffusion of substances into and out of all body cells is low. b)Cells are often located far away from the external surface of the body. How multicellular organism overcome these problem? a)Have specialized structure to increase the surface area for the exchange of respiration gases. b)Have transport system to get gases respiration in and

    keep it at the set point. All homeostatic mechanisms use a feedback loop to inform the body about any changes that occur externally or internally. There are two different kinds of homeostatic mechanisms: a positive feedback mechanism and a negative feedback mechanism. Positive feedback mechanisms boost physiological processes and amplify the system’s action to move the system away from the equilibrium state so it is more stable. Negative feedback mechanisms‚ on the other hand‚ maintain equilibrium

    1. Was the approach to productivity improvement the correct way to implement such a program? No. It was not the correct way. Productivity studies analyze technical processes and engineering relationships such as how much of an output can be produced in a specified period of time. It is related to the concept of efficiency. While productivity is the amount of output produced relative to the amount of resources (time and money) that go into the production‚ efficiency is the value of output relative
