A confounding variable refers to an external effect, which modifies the influence of an independent and dependent variable. This extraneous effect is used to affect the outcome of an experimental design. The confounding variables can ruin the experiment and can generate unnecessary outcomes.
In the given case, confounding variables can be introduced by testing multiple hypotheses at a time and by using distinct kinds of soil in each of the samples.

<span>rate of technological progress. The steady-state growth rate of total output is equal to the rate of population growth (n) plus the rate of technological progress (g). A change in the rate of technological progress will permanently change the growth rate of total output. </span>
Answer:
Cl- ions will move inside the cell.
Explanation:
When the equilibrium potential and is equal to membrane potential, the net charge across the membrane is equal to zero and therefore there is not movement of ions across the membrane. However, in this case, the membrane potential is -70 mV, while the equilibrium of negatively charged Cl- ions is -81 mV. In consequence, Cl- ions will tend to move inside of the cell.
