Suppose that the concentration of Na outside the cell is 100 and inside the cell is 100 mmol/liter. The Nernst equation at 20oC
Fittoniya [83]

Answer:

0 current

Explanation:

Given that:

The concentration of Na inside the cell is 100 mmol/liter

The concentration of Na outside the cell is 100 mmol/liter

where;

z(valence of the ionic species for Na⁺ ) = +1, and the membrane voltage is 58 millivolt

Therefore;

E_{ion} = \dfrac{58}{z} \times log _{10}  \bigg (\dfrac{[ion]_{out}}{[ion]_{in}}\bigg)

E_{ion} = \dfrac{58}{1} \times log _{10}  \bigg (\dfrac{100}{100}\bigg)

E_{ion} =58 \times log _{10}  \bigg (1\bigg)

E_{ion} = 58 \times 0

\mathbf{E_{ion} =0}

HACTEHA [7]

The ovaries are works on developing the egg-containing follicles, the uterus is reacting to the estrogen made by the follicles, reva6mping the lining that was just rid during the last period. This is called the proliferative phase because the endometrium evolves thicker.

<h3>What is the proliferative stage?</h3>

In the proliferative phase, the fibroblasts make collagen that rises wound stability, new epithelial cells cover the wound area, and capillaries join to form new blood vessels.

In the late phase, the production of new and collagen remodels the scar, blood vessels widen, and the epithelium.

Thus, The ovaries are working on developing the egg-containing follicles, the uterus is responding to the estrogen produced by the follicles, rebuilding the lining that was just shed during the last period

Should we start doing genetic testing to determine if someone is a good candidate to be a firefighter, or police officer? Why or
daser333 [38]
Great question! In my opinion anyone can do anything as long as they have the qualifications, take John for example. Let’s say he is a random guy from New York with no genetics in the police department. If john takes the tests and training and qualifies as a police man, it shouldn’t matter what his genetics are. I think testing however is a good idea due to the fact it narrows down the participants who in theory should be good at it etc. And separates the strong from the weak. Hope this helps!
