Ok, so when a horse (with 64 chromosomes) is crossed with a donkey(that has 62 chromosomes), each parent give its child half of its chromosomes. [64/2=32] [62/2=31]. So the mule gets 31 pairs of chromosomes plus 32 pairs of chromosomes. That equals 63 total chromosomes. In order to be a parent, it must give <span>half of its chromosomes to its child. [63/2=31.5] You can't have half a chromosome, so the mule is a sterile organism. Let me know if you have questions.</span>
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.

Answer:
27.5
Explanation:
Divide 75 by 6. You get 12.5. Multiply 12.5 by 2.2 (when converting kilo to pound, you multiply by 2.2) Then, you'll get 27.5. The answer is 27.5 pounds/lbs.
