Mars2501 [29]

Answer:

50% AA and 50% Aa

Explanation:

Punnet square is a tool used to examine the offspring's genotype result of a breeding experiment. We will need to put the genotype of a parent in the row, and other parents at the column. The parent is homozygous(AA) and heterozygous(Aa), the square will be:

                       AA

                 A            A

        A     AA          AA

Aa    a      Aa           Aa

The result will be 50% AA and 50% Aa

Explain how the increased flammability of chaparral shrubs is a beneficial adaptation.
MArishka [77]

Answer:

Trees will compete with shrubs for light and space so by adapting for increased flammability, chaparral scrubs promote natural wildfires to eliminate their competitors. While these fires destroy the trees, the shrubs are still able to germinate afterwards.

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.
