NNADVOKAT [17]
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.

Local and global winds are set in motion by air moving in convection cells. Describe the motion of air in a convection cell. Be
IrinaVladis [17]

Answer:

Due to the earth spherical shape, different latitudes of the planet receive varying solar energy levels from the sun. This is due to the differences in how the sun rays hit the earth surfaces and differences in the length of atmosphere the rays have to travel before they reach the earth's surface.

The equatorial regions get the most energy levels from the sun hence their atmosphere gets heated faster and the hottest. The air mass in this latitude, therefore, gets less fast dense  and begins to rise. The cooler and denser air mass from the poles rushes in, through the  lower atmosphere, to replace the void of the rising air.

When this air mass also gets heated, it too begins to rise. Remember the initial air mass cooled as it rose into the upper atmosphere. This now makes it denser than the air mas below it. As the hotter air mass begins to rise from below it pushes the cooler air mass above laterally. After the lateral movement, the air mass begins to sink slowly as it moves towards the poles because the incoming air mass gets denser than the local air mass.

The lateral movement of the convection current moving to the north is deflected to the north-west due to the Coriolis effect of the earth rotation while the lateral movement of the convection current moving south is deflected to the south-west. These pockets of convection currents are called Hadley cells.

During the localization of a mitochondrial RNA polymerase following its translation, which of the following is least likely to b
Nikolay [14]

Answer:

An electrochemical Gradient

Explanation:

During the translation of mRNA to protein, the nascent polypeptide chain that is formed is not yet a functional protein right after translation. The polypeptide must then undergo another series of processing and packaging and may even need another protein(s) to completely form a functional moiety. Generally, for this a mix of chaperones may be needed to complete the protein synthesis pathway.
