Answer:
El problema es "¿Cuál es la capacidad de solubilidad de los cristales de yodo en diferentes tipos de líquidos?"
Explanation:
Solubilidad es el término que se refiere a la capacidad de las sustancias (solutos) para disolverse en presencia de líquidos (solventes). Así, podemos decir que si Luís quiere saber si los cristales de yodo se pueden disolver en diferentes líquidos, está intentando solucionar el problema de la capacidad de solubilidad de estos cristales.
En este sentido, podemos decir que el yodo no es una sustancia que se disuelva fácilmente en agua, pero sí se puede disolver fácilmente en cloroformo.
Answer:
D) Na+ is used to repolarize the membrane.
Explanation:
Option D is wrong choice because it is K+ which is used to repolarize the membrane not Na+.
As soon as membrane gets depolarized because of influx of Na+ due to opening of voltage gated Na+ channels simultaneous opening of voltage gated K+ channels and closing of Na+ voltage gated channels takes place. As a result of which K+ moves out of the cell leading to drawing of electrochemical gradient out of the cell.
In order to achieve resting membrane potential, more Na+ must be out of the cell and more K+ must be inside the cell. There are many leaky channels on neurons from which Na+ has tendency to leak into the cell while K+ has the tendency to leak outside of the cell. So Na+/K+ pump which is located on the membrane of neuron keeps pushing Na+ outside of the cell and K+ inside the cell so as to maintain resting membrane potential which is -70 mV.

The major difference between lactic acid and alcohol fermentation is the products that are produced. In the 'L.A' fermentation, lactic acid and 150 kJ of energy is produced while in alcohol fermentation, alongside the alcohol (ethanol) and the 210 kJ of energy, carbon dioxide is produced.
In lactic acid fermentation:
C₆H₁₂O₆ ₋₋₋₋₋₋₋₋> 2C₃H₆O₃ + Δ150 kJ
while in alcohol fermentation:
C₆H₁₂O₆ -----------> 2C₂H₅OH + 2CO₂ + Δ210 kJ
