The mechanism that affected the gene pool of the immigrants that entered the United states Through Ellis Island is Gene flow.
Gene flow involves the movement of genes or alleles between interbreeding populations of a particular species. In other words it is the movement of genes from one population to another population. Actually it may be an important aspect of evolution; evolution can occur as a result of genes being transferred from one population to another. Gene flow occurs when there is migration, since the loss or addition of people can easily change pool frequencies even without no other evolutionary mechanisms operating.
The neuronal membrane potential depends on different concentrations of sodium and potassium on either side of the membrane. Ionic concentration gradients are established by the action of the sodium-potassium ion pump, an enzyme that requires ATP. Without ATP, the pump will not function. As a result, the resting membrane potential will not exist and the brain will not function.
What is neuronal membrane?
The neuron and its ionic components can be treated using the ideas mentioned above.
The neuron's plasma membrane is only minimally permeable to Cl and Na+ and extremely permeable to K+. A balance between a high concentration of Na+ and a high concentration of Cl, as well as modest amounts of impermeant anions like bicarbonate, phosphate, and sulfate, is what keeps the extracellular fluid's electroneutrality. The concentration of Cl in the cytoplasm, where K+ concentration is high, is substantially lower than what is required to balance the sum of the positive charges. There, negatively charged impermeant proteins and phosphates keep the environment electroneutral.

Answer:
Dermatophytes
Explanation:
Dermatophytes is a common group of fungi which includes Microsporum, Epidermophyton and Trichophyton. These cause skin diseases in animals including humans. These fungi can cause infections in hairs, nails and skin and feed by obtaining keratin from cells. These usually not invade the living tissues but only infect the superficial layer of the of the outer skin. The skin diseases caused by these fungi include ringworm, athlete’s foot and jock itch.
