The total number of atoms is 3.

Make sure to not confuse elements with atoms. Elements are substances used in a chemical equation that cannot be broken down. There are two elements in H2O: hydrogen and oxygen.

Atoms in the compound is the number of elements. Hydrogen would be one atom, but since it has a subscript of 2, it would mean that there are two hydrogen atoms.  Oxygen is another atom, however, it does not have a subscript. Don't make that fool you because there is actually a subscript which is the understood one. That is why there are three atoms.

Hope this helps!!!

What is the equilibrium membrane potential due to na ions if the extracellular concentration of na ions is 142 mm and the intrac
Ganezh [65]

The equilibrium membrane potential is 41.9 mV.

To calculate the membrane potential, we use the <em>Nernst Equation</em>:

<em>V</em>_Na = (<em>RT</em>)/(<em>zF</em>) ln{[Na]_o/[Na]_ i}

where

• <em>V</em>_Na = the equilibrium membrane potential due to the sodium ions

• <em>R</em> = the universal gas constant [8.314 J·K^(-1)mol^(-1)]

• <em>T</em> = the Kelvin temperature

• <em>z</em> = the charge on the ion (+1)

• <em>F </em>= the Faraday constant [96 485  C·mol^(-1) = 96 485 J·V^(-1)mol^(-1)]

• [Na]_o = the concentration of Na^(+) outside the cell

• [Na]_i = the concentration of Na^(+) inside the cell

∴ <em>V</em>_Na =

[8.314 J·K^(-1)mol^(-1) × 293.15 K]/[1 × 96 485 J·V^(-1)mol^(-1)] ln(142 mM/27 mM) = 0.025 26 V × ln5.26 = 1.66× 25.26 mV = 41.9 mV

Explain how muscle cells, blood cells and small intestine cells work together to keep the body moving.
spayn [35]

Answer:

Cells are considered the fundamental units of life. The cells in complex multicellular organisms like people are organized into tissues, groups of similar cells that work together on a specific task. ... At each level of organization—cells, tissues, organs, and organ systems—structure is closely related to function.

Hope this is helpful :)
