The answer is photosynthesis
I believe the answer is a mineral's crystal shape is determined by its atomic structure.
<span>The paralysis is from a chain reaction of cells not processing sodium properly. This leads to their residing in a resting potential instead of forming action potentials, as is required for them to fire during muscle movements. The electrical impulses are not moving down the cells, leading to their not being able to move and, therefore, paralysis of the affected or poisoned areas.</span>
Answer:
When the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.
Explanation:
According to the Nernst equation the potential of the membrane for a two-compartment model of a cell for positive gradient of K⁺ ions is V = - 60 mVlogK'/K where K' = inside concentration of K⁺ ions and K = outside concentration of K⁺ ions. For a 10 fold excess of KCl in the inside compartment, K'/K = 10. So,
V = - 60 mVlogK'/K = - 60 mVlog10 = -60 mV.
For a negative gradient of Na ions is V = + 60 mVlogK'/K where K' = inside concentration of Na⁺ ions and K = outside concentration of Na⁺ ions. (Since the cell is selectively permeable to Na⁺ ions. So, Na ions to not flow out but in.)For a 10 fold excess of NaCl in the inside compartment, K'/K = 10. So,
V = + 60 mVlogK'/K = + 60 mVlog10 = +60 mV.
So, when the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.
Answer: True
Explanation:
The neuron has leak channels in the cell body, axon and dendrite and cell body. This is because the trans membrane potential exists in all parts of the cell membrane.
Because of this reason the the leak channels are available at each part of the neuron.
The action potential, trans membrane potential should exits in all the parts of the cell so it should be located in all the parts of cell.
