Drag the labels to show how the glucose and hormone levels will change in each mouse after they are joined by parabiosis. labels

NikAS [45]

The labels that will show how the glucose and hormone levels will change in each mouse after they are joined by parabiosis are:

Those of db/db are:

The glucose level: stays the same.
The hormone level: decreases.

Those joined by parabiosis which are Wild type:

Glucose level: stays the same
Hormone level: decreases

<h3>What is the use of parabiosis to evaluate hormone function?</h3>

Parabiosis is known to be a useful and effective tool to examine hormone function.

This is b because it allows the exchange of long-lived molecules (such as hormones) to take place between the two joined organism. Therefore, the glucose levels of each mouse can stay the same, but the hormone levels will be altered.

For the galvanic (voltaic) cell fe(s) + mn²⁺(aq) ⟶ fe²⁺(aq) + mn(s) (e° = 0.77 v at 25°c), what is [fe²⁺] if [mn²⁺] = 0.050 m an

Nuetrik [128]

The concentration of Iron in the galvanic (voltaic) cell Fe(s) + Mn²⁺(aq) ⟶ Fe²⁺(aq) + Mn(s) is 0.02297 M.

<h3>What is the Nernst Equation?</h3>

The Nernst equation enables us to identify the cell potential(voltage) in presence of non-standard conditions in a galvanic cell. It can be expressed by using the formula:

$\mathbf{E_{cell} = E_o - \dfrac{0.059}{n} \times log \dfrac{[Fe^+]}{[Mn^{2+}]}}$

where;

n = Number of electrons = 2
$\mathbf{E_o}$ = Initial voltage = 0.77 V
$\mathbf{E_{cell}}$ = Cell voltage = 0.78 V
$\mathbf{[Mn^{2+}]}$ = Manganese concentration = 0.050 M

Replacing the values into the above equation, we have:

$\mathbf{0.78 = 0.77 - \dfrac{0.059}{2} \times log \dfrac{[Fe^{2+}]}{[0.050]}}$

$\mathbf{0.78 -0.77= -0.0296\times log \dfrac{[Fe^{2+}]}{[0.050]}}$

$\mathbf{log^{-1} (-0.3378) = \dfrac{[Fe^{2+}]}{[0.050]}}$

$\mathbf{Fe^{2+} = (0.4594\times 0.050 )\ M}$

$\mathbf{Fe^{2+} =0.02297 \ M }$
