Answer:A) No; action potentials result in increased permeability of the plasma membrane to sodium.
Explanation
Action potential is generated when influx of sodium ions occurs through the voltage gated ion channels in the nodes of ranvier cells, into the axoplasm. Provided the stimulus is strong enough more Sodium gated channels open and Sodium ions move in.
As sodium pump only pump sodium ions out of the cells , and it is sodium inlfux that causes action potentia,l this does not cause action potential .
In addition ATPs hydrolysis which supply energy for the sodium pump does not lead to action potential.
Answer:
Cells are the simplest structure to fit all of the characteristics necessary to be considered alive.
Explanation:
The cell (from the Latin cellula, diminutive of cella, ‘hollow’) 1 is the morphological and functional unit of every living being. In fact, the cell is the smallest element that can be considered alive.2 In this way, living organisms can be classified according to the number of cells they possess: if they only have one, they are called unicellular (such as protozoa or bacteria, microscopic organisms); If they have more, they are called multicellular. In the latter the number of cells is variable: from a few hundred, as in some nematodes, to hundreds of billions (1014), as in the case of the human being. The cells usually have a size of 10 µm and a mass of 1 ng, although there are much larger cells.
