Hot air always rises from the equator. As this air climbs higher in the sky, it cools. Cool air can hold less water than warm air. This means that as the air cools, clouds form that release most of the water they hold. Because the cooling air is above the equator, the moisture rains back down on the tropics.
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes.
<u>Answer:</u>
<em>The star is travelling away from the earth.</em>
<u>Explanation:</u>
<em>A star’s temperature largely determines its color. </em>Stars with higher temperature have a bluish color and stars with low temperature appear red in color. But the color of star that we observe from the earth is different from its actual color.
<em>This variation in color is due to Doppler effect. </em>When the movement of a star is towards the earth the frequency shifts to the higher frequency region and when the movement is away from the earth the frequency of the light emitted will shift to the lower frequency region. <em>Color of light depends on the frequency. </em>
The color corresponding to the <em>lower frequency region</em> is red and color corresponding to <em>high frequency region</em> is blue. <em>So when the star moves away from the earth it appears red in color.</em>
<span>Cattle and sheep are exposed to lead and zinc when these poisons are in the grass/soil.
Cattle and sheep graze on the grass, and thus they intake these minerals, such as lead and zinc when they come in contact with grass or earth they may eat along with grass. Thus they are exposed to them via eating.
