Answer and explanation:

If a cell has a higher concentration of sodium inside than the sodium concentration that there is outside of it, there will be a chemical gradient that will direct the sodium to the outside, to equate the concentrations between the inside of the cell and the outside of the cell.

The membrane voltage on cells depends on the conductance of each ion. The more conductant an ion is, the more likely is that it will go through the membrane from the inside to the outside or vice versa. This conductivity relies on the number of active protein channels specific to that ion that can be found in the membrane. If the membrane voltage is negative when the cell is at resting potential, it means that the most conductant ion is one whose equilibrium potential is negative as well. Sodium's equilibrium potential is positive, which suggests that there is another ion inside this cell that is more conductant and whose equilibrium potential is negative - probably potassium.

Given that the membrane voltage is negative, which means that there are more positively charged particles outside than inside, the sodium will most likely flow from the outside to the inside - the electrical force on sodium will be from the outside to the inside.

The determining direction of the sodium will be given by the electrochemical gradient and will depend on the magnitude of the chemical gradient and the electrical one.

Answer:

Dmitri Ivanovsky

Explanation:

Dmitri Ivanovsky utilized one of these filters in 1892 to demonstrate that despite being filtered, sap from a diseased tobacco plant remained infectious to healthy tobacco plants. The filtered, infectious substance was dubbed a "virus" by Martinus Beijerinck, and this discovery is regarded as the origin of virology.

Human blood type is determined by multiple alleles (A, B, and O). Which ratio would result from a cross between a man with homoz
Mnenie [13.5K]

Hallo~~

Your question is related to genetics.

Have you ever done a Punnett Square? This question forces you to make one. If your cross a homozygous type A (AA) and homozygous type O (OO) you should get 100% AO. Understanding genetics, an AO gene means a type A blood. Therefore, it's 100% type A blood (AO).
